Hans Zinsser

American physician, bacteriologist (1878–1940)

Rats, Lice and History, a 1935 chronicle describing the life cycle of typhus fever, established Hans Zinsser as a prominent voice in medical literature. Throughout his career, he balanced rigorous laboratory research with an expansive interest in history and poetry, eventually producing over 200 medical articles and books while serving as a professor at Harvard University.

Academic and Professional Training

Born in New York City in 1878, Zinsser attended the Timothy Dwight School before matriculating at Columbia University. He earned his A.B. in 1899, followed by M.A. and M.D. degrees in 1903.

Military Service and Epidemiology

During World War I, Zinsser served with the American Red Cross Sanitary Commission in Serbia and later held the rank of lieutenant colonel in the US Army Medical Corps. His work in France earned him the Distinguished Service Medal for his organization of military sanitation and disease control protocols. Beyond his administrative duties, he was recognized for providing medical care to wounded soldiers under active fire, earning the Order of St. Sava of Serbia.

Research into Typhus

In 1923, Zinsser joined the faculty of Harvard Medical School, a position he held for the remainder of his life. His primary research focus was the study of typhus. His investigations led to the isolation of the typhus bacterium and the development of vaccines for various strains of the disease. His contributions were significant enough that a condition now termed Brill–Zinsser disease bears his name as a recognition of his diagnostic insights.

Literary Contributions and Legacy

Zinsser authored several texts on bacteriology, including Infection and Resistance and his collaborative A Text-book of Bacteriology. His final work, As I Remember Him: The Biography of R.S., was written while he suffered from lymphatic leukemia. Published in 1940, the memoir secured a National Book Award. Following his death in New York City on September 4, 1940, he was interred at Sleepy Hollow Cemetery.
