1880

Morell Mackenzie publishes first volume of Diseases of the Throat and Nose; second volume followed in 1884. First volume immediately recognized as “a classical treatise, the standard textbook of laryngology” (Stevenson[2], 44-46). Abraham Jacobi publishes Treatise on Diphtheria, which argued that the disease was highly contagious but not caused solely by a bacterium. He was uncertain about the agent of transmission, but blamed filth and irresponsible disease carriers (i.e., people with mild cases who felt well enough to work and travel) (Bittel, 184-189).
