Makers of Modern Medicine. James Joseph Walsh

observations on the legs of these animals in order to solve the problems of animal electricity. Pasteur's demonstration that there was no such thing as spontaneous generation, served at first only to bring down on his devoted head the aspersions of most of the distinguished scientific men in Europe. When that genius, the physician Robert Mayer, discovered the conservation of energy as the result of his acute observation, that blood drawn by venesection in the tropics was redder than that drawn in colder climates, he found that scientific circles were not only not ready to accept his demonstration, but that he was looked upon as a visionary, somewhat as one who thought that he had solved the problem of squaring the circle or the endless puzzle of perpetual motion.

      Fortunately these men have as a rule had a physical and mental force that enabled them to go on in spite of the opposition or derision of their contemporaries. It is rather a curious fact that most of the great medical discoverers were born in the country and were as a rule the sons of rather poor parents. Many of them were so situated that they had to begin to make their own livelihood to some extent at least at the beginning of their third decade of life. Far from proving a hindrance to their original work, this necessity seems rather to have been one of the sources of inspiration that spurred them on to successful efforts in their investigations.

      Most of them were what would be called handy men, in the sense that they could use their hands to work out their ideas mechanically. This was typically true of Galvani, who had to construct his own first electrical instruments, and of Laennec, who took pride in making his own stethoscopes. So many of them made by his own hands are still extant, that a number of museums have the opportunity to hold specimens of his handiwork. Auenbrugger and Johann Müller and Pasteur are further examples of this same handiness. Claude Bernard exhibited this quality very early in life and continued to exercise it all during his career.

      Nor was their ingenuity limited to material things. Many of them were interested in literary and artistic work of various kinds. Morgagni was considered a literary light in his generation. Auenbrugger composed a musical comedy which had a distinct success, even in music loving Vienna. The Empress Maria Theresa said that she supposed he would now continue to write musical comedies; but Auenbrugger replied, with more candor than gallantry, that he had something better to do. Claude Bernard composed a play that shows distinct evidence of literary talent. It seems fortunate indeed that he was diverted from his original intention of following literature as a career, and took up medicine. Many of the others, as, for instance, Graves and Stokes, were excellent judges of art, critics of real knowledge and genuine appreciation; and indeed it may be said that none of them was ever so absorbed in his vocation of medicine as not to have much more than a passing interest in some of the great phases of intellectual activity quite apart from his professional work, or from scientific knowledge: an avocation to which he turned for the only true recreation of mind there is–a change of work.

      This seems all the more worth while calling attention to in our strenuous age, because it is sometimes considered a mistake for a physician to show that he is interested in intellectual pursuits of any kind apart from his professional work. It is supposed that no one is capable of dividing his attention in this way and yet do justice to his profession and his patients. As a matter of fact it has well been said that no really great physician has ever been a narrow specialist in the sense that he knew only medicine well; there was always at least one other department of intellectual attainment with which he had made himself so familiar as to be an authority in it. It is not the lopsided who make great athletes, and it is not the one-sided man who succeeds in doing really great work. Practically all the great physicians have had favorite hobbies to which they have turned for relaxation, for surely no one understands better than physicians that recreation consists not in that impossibility, the doing of nothing, but in resting the mind by doing something quite different from what it has been engaged at before.

      There is another phase of the lives of these great men of medicine that is so different from what is ordinarily thought to be the rule with physicians, that it seems worth while emphasizing at the end of this introduction. All these great discoverers have been men of constructive imagination, men who might have been distinguished litterateurs very probably, had they applied themselves in that field. All of them have had too much imagination to be materialists, that is, to consider that they could know nothing except what they learned from the matter with which their studies were taken up. All these great discoverers in medicine have been simple, sincere, faithful believers, ready to express their trust in an overruling Providence, and in a hereafter that they knew only by faith, it is true, but which was for that reason none the less distinctly recognized. While it is usually considered that medicine leads men's minds away from orthodox thinking in the great matter of the relationship of the creature to the Creator, all these men have been not only ready to acknowledge their personal obligations to Him, but have furnished exemplary models of what the recognition of such obligations can make of human lives.

      There is an old proverb that runs Ubi tres medici ibi duo athei, –where there are three physicians there are at least two atheists. This has made many a heartache for fond mothers when they found their sons had determined on becoming physicians. If the present series of sketches is to be taken as any argument, however, it is only the small minds among physicians who become atheists. They are not able to see their way clearly from the material they work in to the higher things that prove a source of strength and consolation to the great minds while they are busy making medicine for their own and subsequent generations. Certainly no more thoroughly representative group of the makers of nineteenth century clinical medicine could have been selected than those whose sketches are here given. They are from all the nations who have contributed materially to modern medical advance, yet all of them were deeply religious men. There is another and equally important point with regard to them. It is their relations to their fellows. Without exception they were men beloved by those around them for their unselfish devotion not only to science, but also to their brother men. In the midst of their occupations the thought that has been the profoundest consolation for all of them without exception has been that they were accomplishing something by which their fellow-men would be saved suffering and by which human life would be made more happy. A study of their careers cannot fail to show the young physician the ideals he must cherish if he would have real and not apparent success and happiness in life.

      MORGAGNI, THE FATHER OF PATHOLOGY

      Let us then blush, in this so ample and so wonderful field of nature (where performance still exceeds what is promised), to credit other men's traditions only, and thence come uncertain problems to spin out thorny and captious questions. Nature herselfe must be our adviser; the path she chalks must be our walk; for so while we confer with our own eies, and take our rise from meaner things to higher, we shall at length be received into her closet-secrets.

      –-HALLER.

      In 1894, when the International Medical Congress met at Rome, Prof. Virchow of Berlin, the greatest living pathologist at the time, was asked to deliver the principal address. He chose as his subject John Baptist Morgagni, the distinguished Italian physician and original investigator of the eighteenth century, whom he hailed as the Father of Pathology. No medical scientist of the nineteenth century was in a better position than Virchow to judge who had been the founder of the science for which he himself did so much. Virchow besides, through long and faithful study of the history of medicine, knew well whereof he spoke. In pathology especially modern medicine has made its sure advances, so that Morgagni's ground-breaking work may well be considered the beginning of the most recent epoch in medical science. As a matter of fact, medicine lost much of its obscurity by losing all its vagueness when Morgagni's methods came into general use.

      As a medical student scarcely twenty years of age, he revolutionized medical observation by studying his fatal cases with a comparative investigation of their clinical symptoms and the postmortem findings. This had been done before, but mainly with the idea of finding out the cause of death and the principal reasons for the illness which preceded. Morgagni's investigations in pathology consisted in tracing side by side all the clinical symptoms to their causes as far as that might be possible. This looks so
