born Nov. 17, 1878, New York, N.Y., U.S. died 1940 U.S. bacteriologist and epidemiologist. He taught principally at the Columbia (1913-23) and Harvard (1923-40) medical schools. He isolated the bacterium that causes the European type of typhus, developed the first antityphus vaccine, and, with colleagues, found a way to mass-produce it. He recognized that cases of mild typhus-like symptoms in lice-free persons are recurrences after a latent period (Brill-Zinsser disease). His best-known book, Rats, Lice and History (1935), recounts the effects of typhus on humankind (he believed disease had destroyed more civilizations than war) and efforts to eradicate it
