old man." Playmate in the years gone by, of Fenger, Billings 2>^ 

 and Herrick (the stars of Chicago's medical madhouse, the 

 Cook county hospital), he had spent his last two in Europe. 

 Most time had gone into Prag where Chiari was then active — 

 he of whom it was said that he carried a microscope in his eye. 

 Here he had been taught the ultimate in morphological pathol- 

 ogy. The fact is remarkable, because what Hektoen taught his 

 pupils was something quite contrary. "Pathology has given all 

 the descriptions and made all the pictures it needs to," he said. 

 Morphology, in other words, was dead. Progress, he insisted, 

 lay in bacteriology, in immunology, in experimental medicine 

 and in dynamic concepts of disease. 



Hektoen's personal accomplishments in scientific medicine 

 bulk large (descriptive essays on myocardial change, neuro- 

 fibrosis, and vascular disease; critical essays on the ray fungi; 

 early evidence for the invasion of the blood stream by micro- 

 organisms as opposed to the "toxic" origin of the peripheral 

 manifestations of disease; early application of physico- 

 chemical methods to immunological problems; transmission 

 of measles from man to man) . Yet some would say that what 

 he accomplished through his induction of productive workers 

 into the field made him a still greater figure. Most were too 

 young to recognize the fact that all their subsequent work 

 was but the ripening of one of Hektoen's brain shoots. Gen- 

 erous in his bestowal of "ideas" upon those who sought him 

 out, he was equally generous in aiding those who came to him 

 with notions of their own. 



When the men who were simultaneously active in Hektoen's 

 laboratory in the years of Wherry's residence there are merely 

 listed, they stand forth as an unbelievable bit of American 

 medical history. Here were E R Le Count (the second pro- 

 fessor of pathology in Rush, authority on the tumors and sharp 

 critic of pathological theory) ; George H Weaver (an assistant 

 professor, ditto, the discoverer of a liver cirrhosis-producing 

 microorganism and the first of the scientific makers of anti- 

 toxine in U S A) ; H G Wells (soon to revise pathology in 

 "chemical" terms and to become its professor in the University 

 of Chicago) ; E C Rosenow (veritable Holstein for scientific 

 productivity, and later the professor of experimental bacteri- 

 ology with the Mayos) ; Thomas Reid Crowder (handicapped
