         FURTHER TALES OF ANGINA: 

A REMEDY AT LAST

 

         Last month’s essay outlined the first descriptions of angina pectoris and its relation to coronary artery disease. William Jenner was probably the first to notice the association of the syndrome with calcification of the coronary arteries. He withheld publication of his findings to avoid frightening his friend and former teacher, John

Hunter. In 1799, Jenner’s colleague, Caleb Parry, a physician in Bath, published a monograph on angina in which he reveals the story of Jenner’s discovery, details three more cases that show diseased coronary arteries at autopsy, and unfortunately confuses the picture by adding syncope as an accompanying symptom in some cases. 

         Osler, in his 1892 textbook, called angina a rare disease, reiterating its rarity in a series of lectures published in 1897. Regarding the cause of anginal chest pain, Osler noted that hardened coronary arteries are

found in many cases with no angina, making it uncertain what actually caused the pain. He listed three main possibilities: a neuralgia of the cardiac nerves, a cramp in the heart muscle, or an extreme tension in ventricular walls (or in the associated nerves) caused by dilatation of the heart from insufficiency of coronary blood flow.

         Treatment since Heberden’s time and until the late 19th century consisted in administration of spirits, plasters, bleeding (to relieve “plethora”), and sometimes opiates or chloroform. Removing a few ounces of blood often prevented recurrent attacks for a short period, probably related to a lower blood pressure. Details of the physiology involved, however, were far from clear. 

         Nitroglycerin, the “modern” treatment for angina pectoris, originated, strangely enough, in homeopathic practice. 

         Dr. Samuel Hahnemann, a well-trained German physician, began the homeopathy movement in 1796. It was based on his idea

Sanuel Hahnemann (Wikipedia)

that if the effects of a drug caused symptoms resembling those of a particular disease, then small doses of that medication would counteract the action of the same disease – “like cures like.” The idea proved attractive and, possibly because patients avoided the traditional bleeding and purging, the practice of homeopathy grew. 

         The chief founder and organizer of homeopathy in America was Constantin Hering. Born and educated in medicine in Germany, Hering was asked by a professor, while training in Leipzig, to write an essay against homeopathy. But when he studied the works of Hahnemann, he became a convert. He landed in America after a shipwreck near the New England coast. He decided to stay, opened a homeopathy practice in Philadelphia, and was instrumental in founding the first school of homeopathy in America. He devoted much time to “proving” medications. Proving was a method, initiated by Hahnemann, by which medications were tested systematically on

humans to observe and record their effects. It was perhaps the first such evaluation of items in the pharmacopeia, an advance over methods of regular physicians.

         Hering was aware of nitroglycerin. An Italian chemist, Ascanio Sobrero (whose face was scarred from an explosion and who knew Alfred Nobel), first synthesized nitroglycerin in 1847 while seeking a better explosive than the available “gun cotton.” Hering “proved” nitroglycerin as early as 1849 and noted that small doses on the tongue rapidly produced throbbing headaches and a rapid pulse, effects Sobrero had also noted. He gave the name “glenoin” to nitroglycerin and, in diluted doses, it became a treatment for headaches and sometimes palpitations. Occasionally it produced an oppressive feeling or even pain in the chest, but it was never promoted for angina, which homeopaths agreed was a rare condition.

         In England, homeopaths were also using glenoin. A British regular physician, Alfred Field, obtained the substance from a homeopathic chemist and reported, in 1858, a single case of a woman with angina-like chest pains who was relieved by nitroglycerin. Others with varied non-chest pains also had relief. The first to use it specifically for angina pectoris was William Murrell, a physician at the Royal Hospital for Diseases of the Chest. He had worked under Burton-Sanderson, one of England’s finest physiologists, and Sydney Ringer (of Ringer’s solution) and was thus trained in experimental techniques. Having read the papers of Sobrero and Field, Murrell made a 1% solution of nitroglycerin and placed a small amount on his tongue. He noted a headache and a sudden bounding of his pulse, so forceful that, just as a patient had entered his office, “I hardly felt steady enough to perform percussion” and, “The pen I was holding was violently jerked with every beat of the heart.” He took nitroglycerine many more times and began to administer it to others, recording pulse, symptoms, and the like. 

         Murrell was aware that the effects of nitroglycerine resembled those of amyl nitrate, an inhaled substance first described as a treatment for angina in 1867. In 1879, he published his experiments


Murrell's first article on nitroglycerine.

with nitroglycerin in a series of four articles, showing that its effects were similar to amyl nitrate but with faster onset of action and longer duration. As an attempt to prevent angina, he gave it as a small tablet to take four times a day. The frequency of anginal attacks in three patients tested diminished, as did the intensity. However, one patient found it easier to simply take a nitroglycerine tablet on the tongue when an attack came on, after which he obtained quick relief. This use of a former homeopathic remedy became the standard approach to managing angina up to the present time. Few medical remedies have enjoyed such a long life.

       TALES OF ANGINA

 

            The oppressive chest pains induced by exertion, known as angina pectoris, have plagued sufferers for centuries. Even the hearts of ancient Egyptian mummies have revealed calcified coronary arteries, an anatomical change that restricts blood flow to the heart muscle that is the usual cause of angina. A full description of anginal pain, recognizing it as a distinct entity to be distinguished from other chest complaints, was first made by William Heberden in an address to the Royal College of Physicians in 1768. The address was published four years later in the Medical Transactions of the Royal Society of Physicians and in the periodical, Critical Review or Annals of Literature, a popular magazine aimed at an educated readership that frequently published medical news.

         Heberden describes angina in the following words: “Those who are afflicted with it are seized, while they are walking, and more

particularly when they walk soon after eating, with a painful and most disagreeable sensation in the breast, which seems as if it would take their life away if it were to increase or continue: the moment they stand still, all this uneasiness vanishes. In all other respects the patients are at the beginning of this disorder perfectly well, and in particular, have no shortness of breath, from which it is totally different.” Heberden adds that he and another physician, whom he discussed the matter with, both noticed a high frequency of sudden deaths within a short time after the onset. Heberden speculated on some sort of “strong spasm” beneath the sternum as the cause of pain, not mentioning heart disease.

          William Heberden was one of the most sought-after physicians in London. Born in 1710 to an innkeeper, his early schooling was at a grammar school that emphasized the Classics. He entered St. John’s College at Cambridge at the age of

William Heberden (Wikipedia)

fourteen, obtained a Bachelor of Arts degree four years later, followed by further study and a medical degree after another eleven years. He taught physic and materia medica for several years at Cambridge and later opened a practice in London. He was a careful observer, taking extensive clinical notes that coalesced eventually into a book: Commentaries on the History and Cure of Disease. His description of digitorum nodi (Heberden’s nodes) appears there. He was a founder of the journal, Medical Transactions, published by the Royal College of Physicians. 

He was conservative regarding the multiplicity of medicines at the time, naming only Peruvian bark for ague, mercury for syphilis, sulfur for the itch (probably scabies), and opium as specific remedies. His broad education and gentle manner attracted many friends and patients, especially from the sphere of literature, such as Samuel Johnson, who dubbed him “ultimus Romanorum,” the last of our learned physicians. He was a friend of Benjamin Franklin, who persuaded him to write a pamphlet on the prevention of smallpox by variolation (inoculation of smallpox virus, a technique used prior to vaccination with cowpox-derived virus), which Franklin published in America on his own press in 1759. The pamphlet was distributed free of charge, the cost being absorbed by Franklin and Heberden. 

         One of Heberden’s patients suffering from angina had willed his body to be dissected when he died. Heberden asked the famous surgeon and anatomist, John Hunter, to perform the autopsy. Helping

Edward Jenner (Wikipedia)

him was Edward Jenner, his 23-year-old pupil in surgery. They found no particular cause of death. Fourteen years later, Jenner, now in practice in the town of Berkeley, autopsied a patient of his with angina pectoris who had died suddenly. While making a transverse section of the heart, Jenner’s knife encountered something hard and gritty. As he wrote to a colleague, Caleb Perry, he looked up at the old and crumbling ceiling, “…conceiving that some plaster had fallen down. But on a further scrutiny, the real cause appeared: the coronaries were become bony canals.” Jenner, sensing that the “bony canals” impaired cardiac circulation and might cause anginal pains, was anxious to publish his finding but hesitated. He had kept in close touch with John Hunter and knew that Hunter himself was having anginal pains. He worried that publication of the idea would have distressed his old mentor and friend.

Knowing Heberden was Hunter’s physician, Jenner wrote to him. He observed that patients with angina had a substantial layer of fat around the heart, and, “as these vessels lie quite concealed in that

substance, is it possible this appearance has been overlooked?” He felt certain that the coronary arteries of Heberden’s previous case had not been examined and he feared that if Hunter learned of his theory of hardened arteries, “it may deprive him of the hope of a recovery.” Heberden agreed that it was best not to publish the findings as Hunter’s anginal attacks sometimes came when he was agitated.

Sadly, a few years later, in 1793, after a dispute at a hospital board meeting, Hunter suddenly collapsed and died. At autopsy, his coronary arteries were “in the state of bony tubes, which were with difficulty divided by the knife,” consistent with Jenner’s speculations.

Edward Jenner later achieved fame with the discovery of the immunizing effect of cowpox against smallpox. He had suppressed his seminal discovery of the hardened arteries in anginal patients out of concern for a friend, a generous act. Heberden and Jenner had opened the way to the study of coronary circulation and its relation to angina pectoris and myocardial infarction. Effective therapies were not to emerge, however, for many years.

                     BENJAMIN FRANKLIN’S GOUT

      Benjamin Franklin’s name is recognized everywhere. No American history course omits mention of his accomplishments. Less often referred to, though, is his struggle with gout and urinary stones, maladies that plagued him in later years.

in France (Wikipedia)

         Franklin first mentioned “a touch of the gout” in a letter to his sister when he was 56 years old. Gout appears off and on in later letters as an annoying but not serious impediment. Franklin, of course, was conversant with many medical and scientific matters, often corresponding with doctors. He knew the writings of Thomas Sydenham, considered the father of English medicine, who had published a treatise on gout in 1683. Sydenham noted that gout “generally attacks those aged persons who have spent most part of their lives in ease, voluptuousness, high living, and too free an use of wine and other spirituous liquors” and “…have

Thomas Sydenham, by Mary Beale
(Wikipedia)

large heads, are generally of a plethoric, moist, and lax habit of body…” When, less often, it attacks younger persons, they received it from gouty parents or occasioned it by “over-early use of venery.” Sydenham also recognized an association with urinary stones, and he discouraged bleeding, emetics, purges, and sweating agents in favor of certain herbal remedies. Leeuwenhoek had seen the needle-like crystals from gouty tophi but identification of uric acid as the important substance came after Franklin’s time.

         Franklin had been sent to France early in the American Revolution to enlist the aid of the French government in the revolt against England. He arrived in December 1776, at the age of seventy. He was well known there, as Voltaire had extolled him as the discoverer of electricity, a genius, a successor to Newton, and a scientist. He took up residence on an eighteen-acre estate in Passy, a wealthy commune near Paris, owned by an aristocrat sympathetic to the American cause.

Franklin commuted to Paris for consultations with the French government, during which he faced numerous meals rich in fatty meats, pastries, and wines, many of the latter fortified. He became especially fond of Madeira and consumed generous quantities of it. His gout intensified and he believed that his new lifestyle was responsible. Lead was often present in wine at the time, entering during its production and seeping in from lead-containing wine vessels. Lead can promote gout by decreasing uric acid clearance and is believed to have contributed to Franklin’s case. 

Madame Brillon, by Fragonard (Wikipedia)

Near Franklin in Passy lived Madame Brillon, the wife of a much older and frequently absent man. Madam Brillon was quite attractive, and she and franklin flirted with each other. During one of Benjamin’s gouty attacks, she composed a poem, chiding him for bringing it on himself by eating too much, drinking too much, avoiding exercise, and “you pass your time with dames” (translated).  He subsequently composed a dialogue  between himself and "Madame Gout," who also berates him for dietary excesses and lack of exercise.

Colchicine, known to the ancients as a remedy for gout, seems to have fallen out of favor in Franklin’s time. He probably did not use it, but it was available in Paris as part of a secret formula called “Eau Médicinale.” Colchicine is derived from the plant Colchicum autumnale, or autumn crocus, found most abundantly in Colchis, an ancient tribal area, described by Herodotus, that covered a region corresponding to the western part of modern Georgia. The identity of colchicine as the secret ingredient in Eau Médicinale was revealed in 1814 and its use in gout subsequently reaffirmed.

Aside from gouty attacks in his feet, Franklin had passed “gravel” in his urine off and on, but it was not until he was 76 that he became aware of a bladder stone that would not pass. The stone troubled him principally when traveling in a coach or walking and he limited his activities to avoid excruciating pain. This hampered his negotiations over the Treaty of Paris of 1783 ending the American Revolutionary War. He medicated himself with large amounts of honey, molasses, and jellies, hoping that they would increase the specific gravity of the urine and allow the stone to be buoyed up and perhaps keep gravel from coalescing. His idea stems from a school of thought known as iatrophysical or iatromechanical medicine, seeking to explain physiological processes through the laws of physics. He could not know the modern conception of urine and stone formation.

Doctors advised another medication for the stone, Blackrie’s Lixivium, a solution of salt of tartar (potassium carbonate), quicklime (calcium oxide) from oyster shells, and water, which is basically a lye solution. Prescribers of this remedy, a remnant of the iatrochemical school of thought, hoped that the lye would dissolve stones. Surgery was discussed among his doctors but dismissed as unreasonable. The operation would have been a lithotomy, removing

the stone through an incision between the scrotum and the perineum, without anesthesia. Founding father and later chief justice John Marshall underwent this procedure in his sixties, successfully. His surgeon was John Jones, a prominent surgeon in the American Revolution, the first to perform a lithotomy in America, and one who could accomplish the surgery in a little over one minute, to minimize pain.

Franklin returned to America in 1785 in ever more pain from the stone. He finally resorted to opiates, which eased the agonies somewhat. He signed the new U.S. Constitution in 1787 but eventually, with John Jones attending him, succumbed to a lung abscess in 1790 at the age of 84. Alert to the end, he lived a remarkably long life for his era, and certainly a productive one.

                                    EISENHOWER’S HEART 

      At about two AM on the morning of September 24, 1955, a severe chest pain awakened President Eisenhower. Thinking it related to a giant hamburger with onions eaten the day before, he got up to find some milk of magnesia. Mamie, hearing the noise, came in and, alarmed at her husband’s appearance, called their family physician, Dr. Howard Snyder. Dr. Snyder, residing nearby, arrived at about 3 AM at the home of Mamie’s mother, outside Denver, where the couple were staying. Eisenhower had suffered from abdominal

pains for years, all through WWII in fact (with no clear diagnosis), and Dr. Snyder apparently thought this might be a manifestation of his usual disorder. He administered morphine which helped the pain. Events thereafter are confused due to differing reports, but it is safe to say that sometime in the late morning Snyder suspected a cardiac origin of the pain and called nearby Fitzsimons Army Hospital, requesting an EKG machine. The commander of the hospital and the chief cardiologist, Dr. Byron Pollock, came and quickly diagnosed an anterior myocardial infarction. 

         Ike was helped down the front stairs into the presidential limousine, driven by a circuitous route to avoid the press, and delivered to the back door of Fitzsimons Army Hospital. Once in bed, covered by an oxygen tent, he received more morphine, along with papaverine (thought to open up the coronary arteries), atropine (thought to help prevent arrythmias), and heparin, followed by Coumadin (for anticoagulation). Dr. Thomas Mattingly, chief of cardiology at Walter Reed Hospital and Dr. Paul Dudley White, who had been a mentor of Mattingly and was at the time probably the best-known cardiologist in the country, were called in for

consultation. They all concurred on the prescribed regimen. Eisenhower, unhappy about the previous cover-ups of the illnesses of FDR and Woodrow Wilson, ordered that the public be informed of events.

         Interestingly, during the previous few days Eisenhower had been fishing near the continental divide, at about 8900 feet, without any chest complaints. His blood pressure was known to be mildly elevated at times, especially when angry. His cholesterol was about 200, he was not overweight, he exercised regularly and, though previously a heavy smoker, he had given it up abruptly in 1949.

         The choice of Paul Dudley White (“P. D.” to friends) as the civilian consultant was a fortunate one. White was a founder of the American Heart Association, author of numerous books, including a standard textbook on cardiology, and a physician consultant to a number of celebrities. He had transported to the Massachusetts General Hospital their first EKG machine from the laboratory of Dr. Thomas Lewis, in London, in 1914. Equally important, White was smooth and tactful with the press.

         Eisenhower was not treated in a cardiac care unit at Fitzsimons. In fact, treating heart attacks at home was still a common and recommended practice. The first CCU in the world opened seven years later, in Kansas City in 1962. The essential components of a CCU, such as external pacemaking, electroshock for ventricular fibrillation, and closed chest massage for cardiac resuscitation were not worked out until 1960. Monitoring with oscilloscopes was possible, and drugs such as quinidine, procainamide, and digitalis were available, as was anticoagulation. CCUs proliferated worldwide once the necessary elements were in place. 

         Eisenhower’s clinical course was fairly smooth, though the infarct was a large one. Six weeks of bed and chair existence was the favored regimen at the time, followed by a gradual increase in exercise. Eisenhower left the hospital after seven weeks. About nine months later, he developed an intestinal obstruction, relieved by surgery, at which time the diagnosis of regional ileitis, or Crohn’s

disease, became apparent. It was certainly the reason he had had so much intestinal distress over the years. After a somewhat slow but steady recovery, Eisenhower ran for a second term as president and completed his time in office without major medical problems.

         In November 1965, now retired and in Georgia, Ike had another, milder, attack. After stabilization, he was transferred this time to a modern CCU in Walter Reed Hospital, where he stayed five weeks, still on the bed and chair regimen. Two and one-half years later, in California, recurrent chest pains landed him in the hospital at March Air Force Base from where he was flown back to Walter Reed. This infarction was complicated by multiple episodes of ventricular fibrillation, uncontrolled by drugs. It required a total of fourteen external shocks to Eisenhower’s chest before the rhythm settled down. “He died fourteen times,” it was said. Amazingly, he remained alert and calm through most of the ordeal. 

Walter Reed Hospital (Wikipedia)

But the old soldier’s time was running out. Before he could be discharged, another intestinal obstruction prompted a second operation that he endured successfully, though it weakened him. His heart failed to rally after the surgery, and he expired quietly on March 28, 1969. An autopsy confirmed extensive three-vessel coronary disease and scarring of the heart muscle. His final stay in Walter Reed Hospital had lasted for approximately ten months.

         Dwight Eisenhower’s staff generally reported his medical problems correctly, as he had asked, though sometimes minimizing their severity. And, importantly, Ike’s cardiac illness helped promote awareness and knowledge of heart disease among the general public.

CHRISTMAS DISEASE

 

 

         In the final issue of the British Medical Journal for 1952, an article appeared with the intriguing title: “Christmas Disease: A Condition Previously Mistaken for Hemophilia.” The authors described a new bleeding disorder found in seven patients. Case number one was a five-year-old boy named Christmas (not stated if this was a first or last name), who had suffered several bleeding episodes after play-induced injuries. All seven cases were indistinguishable from standard clinical hemophilia except that, strangely, bleeding could be stopped by transfusion of plasma taken from hemophilic patients. The authors explain the name given to the disorder, noting that the practice of naming diseases after patients was introduced by Sir Jonathan Hutchinson and had the advantage that “no hypothetical implication is attached to such a name.”

Jonathan Hutchinson was born into a Quaker family in northern England. He was apprenticed briefly to a local doctor, attended

 Jonathan Hutchinson (Wikipedia)

medical school in York, and, in 1850, finished medical training at St. Bartholomew’s Hospital in London. There he befriended other Quakers, such as Thomas Hodgkin, Joseph Lister, and Wilson Fox (later physician in ordinary to the queen), the latter two still in medical school. He became a member of the Royal College of Surgeons and opened a practice. He joined the staff of the Royal London Ophthalmic Hospital, where one of his assistants was Warren Tay, first describer of Tay-Sachs disease, and he attended at the Blackfriar’s Hospital for Skin Diseases. In this way he accumulated broad clinical experience, earning a reputation as a “generalized specialist.” He became an authority on syphilis, wroting a large book on the subject, and created the Archives of Surgery, a journal lasting a decade that was truly his own since he wrote virtually all the articles. 


 Skin cancers arising in arsenic-related keratitis (from Hutchinson's Archives of Surgery,

, v 2. (Hathi Trust)

           With a friend, he resurrected the expired Sydenham Society as  the “New Sydenham Society.” It brought translated European medical works (and writings of British authors) to British doctors. He persuaded the British Medical Association to open a medical museum, edited the British Medical Journal for a time, and even opened his own private museum (focusing on natural history), a sign of his passion for collecting. He started a postgraduate school where practitioners, from home and abroad, could be brought up to date on the latest findings. This endeavor floundered, however, from lack of interest.

         He is known for two failings. Although a keen observer and ardent collector, he did not investigate, as did the great surgeon and collector, John Hunter, with whom he was often compared. Secondly, he inexplicably insisted that leprosy was caused by the consumption of spoiled or rotting fish, even after the discovery of the causative organism was widely accepted. The breadth of his clinical acumen is what impressed colleagues, though. He was, as William Osler put it, “the last of the polymaths, the man at home in all spheres of medical practice.”

         What about naming diseases after patients? Hutchinson, an astute observer, is said to have published over 1000 case reports and, indeed, many contained names coined after patients. Examples are Mortimer’s malady (later considered sarcoidosis), Penman disease, Hilliard’s lupus, and Branford legs. Readers of his reports often reversed the process and invented eponyms in the Hutchinson name. “Hutchinson’s triad” is known to medical students as designating three features of congenital syphilis, one of which is “Hutchinson’s teeth,” (notched and small central incisor teeth). Hutchinson’s facies, Hutchinson’s angina, Hutchinson’s patch, and others placed his name for posterity in various publications. 

         

          But back to Christmas disease, which is of great historical interest. As knowledge of genetics and hematology progressed, “Christmas disease” took the name factor IX deficiency or hemophilia B, a sex-linked recessive bleeding disorder carried by females but affecting males almost exclusively. It constitutes about 15-20% of hemophilia cases. This disorder was a burden on royal families, the afflicted males all descending from Queen Victoria. Queen Victoria’s granddaughter, Princess Alexandra, married to Tsar Nicholas II of the Romanov family, had a son, Alexei, heir to the throne, who bled easily. The family's bodies were unearthed from a grave near the Ural town of Yekaterinburg in 1979. Forensic DNA

studies showed them to be members of the Romanov family. Samples from the exhumed body of Alexander III, Nicholas’s father, and from living descendants were examined to confirm the relationships. Remains of two of the royal children were missing, however: Alexei, the potential heir, and Anastasia. Only in 2007, were bone fragments found buried nearby that proved on DNA analysis to belong to the two missing children. Further study revealed that Alexei had the genetic mutation characteristic of factor IX deficiency, or Christmas disease.



         The mutation exerted tragic effects on descendants of Queen Victoria. One son, two grandsons, and five great-grandsons died of excessive bleeding. The remaining great-grandson, Alexei, was murdered before the disease took its course. One can only speculate on what other avenues history might have taken if the family had not been plagued by the bleeding disorder. Victoria’s own son, Leopold, grew old enough to marry and have a child, but at age 30 he had a fall, dying while his wife was pregnant with their second child. Prince Maurice, son of Victoria’s daughter Beatrice (a known carrier), died on the front in WWI, and probably did not have the disease, or at most a very mild form. No antecedents to Queen Victoria with the altered gene have been discovered and it is presumed that a spontaneous mutation occurred in her genes or those of the immediate prior generation.

 

         But enough of this melancholy narrative on Christmas disease. More joyfully: Merry Christmas and Happy Holidays to all!

                                MEDICINE AT HIGH ALTITUDES

 

         In the late nineteenth century, high-altitude ballooning became popular and adventurous mountain trekkers found ever-higher peaks to conquer. At the extreme elevations participants in both activities encountered difficulties that eventually led to a new specialty: high-altitude medicine. 

         The title, “father” of high-altitude physiology (and of aviation medicine),” is usually awarded to Paul Bert, a French physician and investigator. Another French physician, though, deserves to be included as a “co-father” – Denis Jourdanet. The work of the two might be considered a collaboration between a laboratory investigator, Bert, and a clinically oriented physician, Jourdanet, with Jourdanet supplying the funds.

         Paul Bert (1833-1886) was born in the Burgundy area. He trained as a lawyer but he was intrigued by the mysteries of nature and

eventually took enough courses to sit for a degree. Claude Bernard, one of his examiners, was so impressed with his thesis on respiratory physiology that he took him on as an assistant after he first obtained his medical degree. Bert did experiments on tissue grafting, said to have been helpful to surgeons in the Franco-Prussian War and for which he received a prize from the Academy of Sciences. Bernard got him a professorship at the University of Bordeaux followed by one at the Sorbonne. Bert was politically active, very left-wing, and constantly at odds with the Jesuits. His university appointment was opposed by a group of bishops but, with the influence of Louis Pasteur, he obtained it.

mountains and remained there until university age, then studied medicine in Paris. Restless, he shipped off to Mexico before finishing his degree and set up a practice in the Yucatan peninsula. Through the French consul he became well-connected and married the daughter of a wealthy Mexican diplomat. After a return to Paris to obtain his medical degree he moved to Mexico with his wife, who had tuberculosis, and settled, eventually, in Mexico City, where he joined the faculty of the medical school. His wife improved temporarily at their 2240-meter altitude leading Jourdanet to become interested in the effects of altitude and measure barometric pressures on various mountaintops. His wife succumbed to TB in 1859 and he returned to Paris, where he published on the beneficial effects of higher altitudes and drew attention to the similarity of the symptoms of anemia and those seen after rapid ascent to high altitude.

         He designed low pressure air chambers for treatment of tuberculosis and other illnesses and published a book on his work in 1861. That same year France invaded Mexico and shortly after

installed Maximilian as Emperor. Maximilian asked Jourdanet to be his personal physician but Jourdanet declined (wisely). In 1865 he remarried into another wealthy Mexican family and eventually settled in Paris to conduct research. It was then that he met Paul Bert.

         Bert was aware of Jourdanet’s idea that a deficiency of oxygen was the common factor responsible for the comparable symptoms seen with anemia and high-altitude exertion and wanted to study this using low-pressure chambers. Lacking funds, he advertised openly for money and Jourdanet, now wealthy, answered the call. Meanwhile Jourdanet continued treatment of various diseases with the low-pressure chamber, which he called “aerotherapy.” (He was not the first to use this treatment.) In 1875, he published a large tome, Influence de la Pression de l’Air sur la Vie de l’Homme, a two-volume work with numerous illustrations. Following an extensive historical background, he describes his treatment methods and lays out his ideas on hypoxia as the common problem in anemia and high altitude.

         Paul Bert, grateful for the support of Jourdanet, used both high and low-pressure chambers to establish the critical role of oxygen. He subjected animals and humans, including himself, to low pressure states, then reversed the symptoms with added oxygen.

Conversely, he deprived the air of oxygen at normal pressures, all the while measuring partial pressures of oxygen and CO2 in the blood. He was the first to map the hemoglobin disassociation curve, though his version was incomplete, and establish that the partial pressure of oxygen is the determinant factor.

         Bert eventually, in 1878, produced his magnum opus, La Pression Barométrique: Recherches de Physiologie Expérimentale. In it he describes his experimental work and presents a thorough history of high-altitude studies and lore up to 1878. In the introduction he gives full recognition to the help he received from Jourdanet, both financial and scientific. The work did not achieve the praise it deserved at first, allegedly because Bert was involved in several political activities that diverted attention, but in time it was recognized as a master work that has endured.

         Bert was indeed involved in political activities. He was especially forceful in promoting free, secular, and obligatory education with no church involvement. He wrote a science textbook for use in schools. He became a member of the Chamber of Deputies and eventually Minister of Public Instruction. Finally, he was sent to Hanoi to become Governor General of French Indochina, where he liberalized the French rule and reduced the role of the military in governance. Sadly, after only five months in office, his life and career ended with a bout of severe dysentery.

         Many investigators subsequently refined the relation of oxygen to hemoglobin, determined that oxygen diffused into blood and was not secreted (the latter a position held by J. S. Haldane), and worked out the physiology of high-altitude pulmonary edema and acute and chronic mountain sickness. The benefits continue to flow to mountaineers, pilots, and intensive care units.
