Published in 1935, Rats, Lice and History is a popular science book by bacteriologist Hans Zinsser. The work serves as a "biography" of typhus, tracing the destructive path of the disease throughout human history. Zinsser argues that infectious diseases, including typhus, plague, cholera, and typhoid, have had a far more significant impact on the course of human history than the military strategies of great generals like Caesar, Hannibal, and Napoleon.

The Thesis of the Book
Zinsser's central thesis is that the fate of nations has been shaped more by the typhus louse, the plague flea, and the yellow-fever mosquito than by swords, lances, and machine guns. He suggests that while generals receive the credit for victory and epidemics are blamed for defeat, the reality is that epidemics often decide the outcome of military campaigns.
Structure and Content
The book is divided into sixteen chapters, with the first twelve serving as a preparation for the lay reader. These early chapters cover a wide range of topics, including:
- Scientific Definitions: Exploration of bacteria and other parasites, and the origin of life.
- Ancient World Diseases: Analysis of how diseases of the ancient world affected political and military history.
- Causal Vectors: Detailed information on the rats and lice that act as vectors for typhus.
Zinsser's writing style is is characterized as wry, literate, and discursive. He frequently references classical works and quotes passages in Latin, French, and German, reflecting his broad education in both the liberal arts and science.
Reception and Influence
Upon its release, Rats, Lice and History received an overwhelmingly positive reception. It reached the top ten in nonfiction bestsellers in 1935, according to The New York Times. Critics praised Zinsser's ability to blend deep scientific expertise with a humanistic approach to history, avoiding the "taint of popularization" while remaining accessible to the lay reader.
The book's ideas have echoed in later works such as Plagues and Peoples and Guns, Germs, and Steel, influencing generations of scientists and physicians who were inspired to pursue scientific careers based on their reading of the book.
