Makers of Modern Medicine

by James J. Walsh

The history of pulmonary consumption in its most modern phase is centred around the names of three men, Laennec, Villemin, and Koch. To Laennec will forever belong the honor of having fixed definitely the clinical picture of the disease, and of having separated it by means of auscultation and his pathological studies from all similar affections of the lungs. Villemin showed that it was an infectious disease, absolutely specific in character, and capable of transmission by inoculation from man to the animal. To Koch the world owes the knowledge of the exact cause of the disease and consequently of the practical method for preventing its spread. The isolation of the bacillus of tuberculosis is the great triumph of the end of the nineteenth century, as the separation of the disease from all others by Laennec was the triumph of the beginning of that century. There is [{136}] still room for a fourth name in the list, that of the man who will discover a specific remedy for the disease. It is to be hoped that his coming will not be long delayed.

The estimation in which Laennec was held by the most distinguished among his contemporaries, may be very well appreciated from the opinions expressed with regard to him and his work by the best-known Irish and English clinical observers of the period. Dr. William Stokes, who was himself, as we shall see, one of the most important contributors to our clinical knowledge of diseases of the heart and lungs in the nineteenth century, said with regard to the great French clinician whom he considered his master:

"Time has shown that the introduction of auscultation and its subsidiary physical signs has been one of the greatest boons ever conferred by the genius of man on the world.
"A new era in medicine has been marked by a new science, depending on the immutable laws of physical phenomena, and, like the discoveries founded on such a basis, simple in its application and easily understood--a gift of science to a favored son; one by which the ear is converted into the eye, the hidden recesses of visceral disease open to view; a new guide to the treatment, and a new help to the ready detection, prevention and cure of the most widely spread diseases which affect mankind."

Dr. Addison, who is best known by the disease which since his original description has been called by his name, was no less enthusiastic in praise of Laennec's work. He said:

"Were I to affirm that Laennec contributed more toward the advancement of the medical art than any other single individual, either of ancient or of modern times, I should probably be advancing a proposition which, in the estimation of many, is neither extravagant nor unjust. His work, [{137}] De l'Auscultation Mediate, will ever remain a monument of genius, industry, modesty and truth. It is a work in perusing which every succeeding page only tends to increase our admiration of the man, to captivate our attention, and to command our confidence. We are led insensibly to the bedside of his patients; we are startled by the originality of his system; we can hardly persuade ourselves that any means so simple can accomplish so much, can overcome and reduce to order the chaotic confusion of thoracic pathology; and hesitate not in the end to acknowledge our unqualified wonder at the triumphant confirmation of all he professed to accomplish."

These tributes to Laennec, however, from men who were his contemporaries across the channel, have been more than equalled by distinguished physicians on both sides of the Atlantic at the end of the nineteenth and the beginning of the twentieth century. While we might hesitate to accept the opinions of those who had been so close to him at the beginning of the new era of physical diagnosis, there can be no doubt now, after the lapse of three-quarters of a century, of what Laennec's influence really was, and the tributes of the twentieth century place him among the few great geniuses to whom scientific medicine owes its most important advance.

At the annual meeting of the State Medical Society of New York held in Albany at the end of January, 1903, the president of the society, Doctor Henry L. Elsner, of Syracuse, in his annual address devoted some paragraphs to a panegyric of Laennec. He wished to call attention to what had been accomplished for scientific medicine at the beginning of the last century by a simple observant practitioner. In the course of his references to Laennec and his work he said:

"It is by no means to be considered an accident that, [{138}] among the greatest advances in medicine made during the century just closed, the introduction of pathological anatomy and auscultation into the practice of medicine at the bedside were both effected by the same clear mind, Laennec. He is one of the greatest physicians of all time."

He then quoted the opinion of a distinguished English clinician, Professor T. Clifford Allbutt, who is well known, especially for his knowledge of the history of medicine. Professor Allbutt is the Regius Professor of Physic (a term about equivalent to our practice of medicine) of Cambridge University, England, and was invited to this country some years ago as the representative of English medicine to deliver the Lane lectures in San Francisco. During his stay in this country he delivered a lecture at Johns Hopkins University on "Medicine in the Nineteenth Century," in which he said, "Laennec gives me the impression of being one of the greatest physicians in history; one who deserves to stand by the side of Hippocrates and Galen, Harvey and Sydenham. Without the advances of pathology Laennec's work could not have been done; it was a revelation of the anatomy of the internal organs during the life of the patient."

René Theodore Hyacinthe Laennec, who is thus conceded by twentieth century medicine a place among the world's greatest medical discoverers, was born February 17, 1781, at Quimper in Bretagne, that rocky province at the north of France which has been the sturdy nursing mother of so many pure Celtic Frenchmen who have so mightily influenced the thought not only of their own country but of all the world. The names of such Bretons as Renan and Lamennais have a universal reputation and the province was even more distinguished for its scientists.
