John Grove

Born in 1815 and died in 1895, John Grove is identified in major library records as the author of Epidemics Examined and Explained: or, Living Germs Proved by Analogy to be a Source of Disease, published in London in 1850. Catalog records from the National Library of Medicine and other library sources confirm the book and its publication details.

That work is the main reason Grove is remembered today. In it, he argued that epidemic disease was caused by living germs rather than by purely chemical processes, making the book an interesting early contribution to the long history of germ theory. Modern readers can still access the text through public-domain editions, which has helped keep his name in circulation.

Reliable biographical details beyond his dates and authorship are limited in the sources found here, so it is safest to view him as a 19th-century medical writer whose reputation rests chiefly on this unusually forward-looking study of epidemics.
