John Gould Anthony

Died 16 Oct 1877 at age 73 (born 17 May 1804).American conchologist who was was recognized as an authority on the American land and fresh-water mollusca. During a career in business, his interest in natural history led to a collection of freshwater mollusks of the Ohio River. From 1835 on, he corresponded with mollusk researchers and began to publish his findings. Serious eye trouble (1851) forced his retirement from business. In 1853, he toured Kentucky, Tennessee, and Georgia to collect mollusks. His publications attracted the attention of Professor Agassiz, who asked him to take charge of the conchologieal department of the Museum of Comparative Zoology, Harvard (1863), where he remained until his death. He accompanied Agassiz on the Thayer expedition to Brazil in 1865.
