핵심 특성
주요 업적
1882년 3월 24일 코흐는 베를린 생리학회에서 한 간균이 결핵의 원인이라고 발표했다. 그는 새로운 염색법으로 이 균을 보여 주었고, 응고시킨 혈청에서 배양했으며, 그 배양균으로 실험동물에게 같은 병을 일으켰다. 1905년 노벨 생리학·의학상은 결핵에 관한 그의 연구와 발견에 수여되었다.
코흐는 프로이센 포젠주 볼슈타인에서 지역 보건의로 일하면서 진료실 한쪽에 마련한 실험실에서 탄저병을 연구했다. 1876년 논문에서 그는 탄저균이 자라고 포자를 만드는 과정을 추적했고, 생쥐를 길게 이어 가며 병을 옮겼다. 그의 제자 프리드리히 뢰플러는 훗날 1887년에 펴낸 세균학사에서 이 연구를 자세히 기술했다.
1883~1884년 코흐는 독일 콜레라 조사단을 이끌고 이집트와 인도에 갔으며, 캘커타에서 쉼표 모양의 간균을 순수배양으로 분리하고 조사한 모든 콜레라 환자에게서 이 균을 확인했다. 1892년 함부르크 유행을 다룬 글에서 그는 강물을 여과해 쓰던 이웃 도시 알토나와의 경계를 신중한 모래 여과의 근거로 제시했다.
삶의 장면들
1883년 9월 17일 알렉산드리아에서 보낸 첫 공식 보고서에서 코흐는, 모든 초기 콜레라 환자에게서 발견된 간균이 아직 원인이라는 증거는 되지 못한다고 썼다. 균의 침입이 병을 일으킨 것이 아니라 병의 결과일 수도 있다는 이유였다. 그는 베를린에서 데려간 생쥐와 원숭이, 개, 닭에게 먹이거나 접종한 실험이 모두 실패했다고 보고했다. 1년 뒤 그에게 비판적이던 영국 동물학자 레이 랭커스터는 그가 동물에서 병을 재현하지도 못한 채 원인을 선언했다고 비난했다.
자기 발견이 아직 보여 주지 못하는 것을 분명히 적어 둔 태도는 이 프로필의 분석적 엄밀성 점수와 부합한다. 랭커스터의 비판은 그 옆에 놓아 둘 만하다. 코흐의 이후 인과 주장이 동물 실험 증거보다 앞서 나갔기 때문에 이 프로필은 이 특성을 중간 정도로만 평가한다. 분석적 엄밀성
1882년 9월 제네바 국제위생회의에서 루이 파스퇴르는 강연을 통해 탄저병에 관한 코흐의 연구를 비판했다. 코흐 자신의 기록에 따르면 그는 회의장에서는 짧게 항의하는 데 그친 뒤 상세한 반론을 글로 펴냈다. 그는 이 글에서 파스퇴르가 백신 제조법을 비밀에 부치고 유리한 실험 결과만 보고한다고 비판하면서도, 파스퇴르의 다른 학문적 공로는 인정했다.
즉석 공방 대신 상세하고 날카로운 반론을 글로 내놓은 선택은 이 프로필의 높은 갈등 감내 점수를 보여 주는 한 예다. 다만 이 글은 길고 양쪽이 모두 공세를 편 논쟁에서 코흐 쪽의 주장이므로, 누가 옳았는지보다 그가 어떻게 싸웠는지를 보여 준다. 갈등 감내
전환점
1890년 8월 코흐는 기니피그의 결핵을 멈추게 하는 물질을 발표했다. 11월에는 이것으로 초기 폐결핵을 치료할 수 있다고 썼지만, 제조 방법은 밝히지 않았다. 몇 달 지나지 않아 상태가 나빠지거나 숨진 환자들에 관한 보고가 이어지며 이 약은 신뢰를 잃었고, 그는 대중과 정부의 압력을 받고서야 대략적인 성분을 공개했다. 그는 1897년 개량 투베르쿨린을 발표했으며, 1905년 노벨상 강연에서도 요양소에서의 투베르쿨린 치료를 권했다.
초기의 실패 이후에도 오랫동안 투베르쿨린에 대한 믿음을 유지한 모습은 이 프로필의 낮은 신념 수정 점수와 나란히 놓인다. 역사학자 크리스토프 그라트만은 이 사건을 결핵에 대한 자신의 기존 설명에 대한 집착에서 비롯된 자기기만으로 읽으며, 파스퇴르 학파와의 경쟁과 제도적·재정적 압박이 이를 강화했다고 본다. 이는 하나의 학술적 해석이지, 그의 동기에 대한 확정된 판단은 아니다. 입장 수정 성향

Ray Lankester, 'The Truth about Koch's Cholera Germ', Pall Mall Gazette, 6 Oct. 1884, pp. 1-2 (Wellcome Library copy, archive.org b30476379, OCR full text), read in full -- NON-SELF, ADVERSARIAL CONTEMPORARY (British zoologist, Professor at University College London; writes amid Anglo-German rivalry and openly says English men of science felt 'a certain sense of shame' that Germany led the India work). Read: his praise of Koch's tuberculosis proof by pure culture and reinoculation and his view of Koch as 'a conscientious reporter of his observations' whose account was 'perfectly candid and convincing'; his complaint that Koch let the public be 'mystified' by press reports for months before publishing; his charge that the Sept. 1884 report made a 'dogmatic declaration' that the comma bacillus 'must and shall' be regarded as the cause although no inoculation had reproduced cholera; Timothy Lewis's claim that the organism matched a mouth spirillum; and his attribution of the haste to German-French rivalry ('a rival to the French investigator Pasteur'). Hostile and partly wrong in hindsight about the organism; used as contemporary adversarial evidence about Koch's evidentiary standard and assertiveness, not as fact about cholera.

Read: Koch's use of the Hamburg/Altona water-supply boundary as an experiment that 'performed itself on more than a hundred thousand human beings'; his personal checking of contrary claims about house connections ('on the basis of information received by myself in Altona and Hamburg'); his sharp, sarcastic reply to Pettenkofer ('the revered Herr Localist in his embarrassment'); the protocolled interview of the Nietleben filter attendant and his computation of filtration rates; his insistence that filtration protects only if managed as strictly as at Altona; dismissal of Finkler's bacteria as the product of 'egregious blunders'. Gairdner (non-self, admiring) notes that 'many persons in this country ... have little confidence in Professor Koch' after the tuberculin failure, and that some will not 'coincide with the highly controversial attitude of Dr Koch in rebutting the ideas of his opponents', while praising the 'firm and logical statement of his arguments'.

Read: Koch's serial transmission of anthrax from mouse to mouse 'durch lange Reihen von Generationen' (longest series twenty mice); step-by-step observation of growth and spore formation in a drop of aqueous humour on a heated stage; germination of spores followed back to bacilli; controls showing that other spore-forming bacilli from putrefying matter or hay infusions did not produce inoculation anthrax; drying and wetting tests on bacilli vs. spores and his explanation of soil/pasture outbreaks; his 1877 cover-glass drying, aniline staining and photography so that pictures would be free of 'willkürlicher oder unwillkürlicher Entstellung'; photographic distinction of B. subtilis from B. anthracis (flagella, cut-off ends); his search ('nach langem Suchen') for an illumination apparatus ending with the Zeiss/Abbe condenser.

Ernst, Harvard professor of bacteriology). Read: the Wollstein consulting room partly converted into a laboratory with photomicrographic apparatus and dark room; the 'bitter controversy with Pasteur'; the 1887 cholera report bearing 'the marks of painstaking research and great accuracy'; the 'forced circumstances surrounding the announcement' of tuberculin and the disappointment; his characterisation of Koch's 'patience, a strong will and great persistence', modest manner and clear diction early, and in later life 'a tendency to general and dogmatic statement, and a greater inclination to controversial methods than had been seen before'.

Read: the motto 'nunquam otiosus' on his first scientific paper; 'the thoroughness with which he discussed any subject, and the firmness with which he defended any theory or fact which he thought right'; his repeated government assignments to local epidemics.

Read: arrival when the Egyptian epidemic was already declining; the specific bacilli found in the intestinal wall of all fresh cholera cases and absent in a post-cholera case and in other deaths; his explicit statement that coincidence 'noch nicht' proved causation and that the bacterial invasion might be secondary; that he had earlier set no value on the same finding in Indian material because of possible putrefaction; 50 mice brought from Berlin plus monkeys, dogs and hens fed and inoculated without any result; his request to extend the expedition to India, offering to lead it; in Calcutta, isolation in gelatine culture, detection in all cholera cases and absence in eight non-cholera corpses (pneumonia, dysentery, phthisis, kidney disease) and in animal intestines, and his conditional argument that exclusive occurrence would make the causal link hardly doubtful 'selbst wenn die Reproduktion der Krankheit an Tieren nicht gelingen sollte'.

Read: that at the Geneva hygiene congress (Sept. 1882) he limited himself to 'einen kurzen Protest' against Pasteur's 'persönlich' and 'gereizt' polemic and reserved a full written reply; his statement of method -- it is 'noch nicht bewiesen' that all infectious diseases are parasitic, so proof must be furnished case by case, starting with exhaustive microscopic study using every staining and sectioning technique; that he disputed not Pasteur's chicken-cooling fact but its interpretation, citing 'vielfache eigene Versuche' with other birds; his principle that whoever claims the scientific world's trust 'hat die Pflicht, die von ihm befolgten Methoden so zu veröffentlichen, daß ein jeder in den Stand gesetzt wird, jene Angaben auf ihre Richtigkeit zu prüfen', with his charge that Pasteur kept his attenuation methods secret and reported only favourable trial results (Packisch, Hungary); and his acknowledgement of Pasteur's 'bedeutenden Verdiensten'. A polemical text; used for Koch's own stated standards and conflict style, not as a judgement on Pasteur.
