George Washington Tryon Jr. (20 May 1838 – 5 February 1888) was an American

malacologist Malacology, from Ancient Greek μαλακός (''malakós''), meaning "soft", and λόγος (''lógos''), meaning "study", is the branch of invertebrate zoology that deals with the study of the Mollusca (molluscs or mollusks), the second-largest ...

Biography

George Washington Tryon was the son of Edward K. Tryon and Adeline Savidt. In 1853 he attended the

Friends Central School Friends' Central School (FCS) is a Quaker, independent, coeducational, college-preparatory day school for students in Nursery though grade 12. It is located on 41 acres across two campuses in Wynnewood, a community in Lower Merion Township, Pe ...

in Philadelphia. In 1859, Tryon became a member of the

of Philadelphia. He was largely responsible for the construction of new buildings for the Academy, especially, in 1866, a section for malacology. In 1869 he became the conservator in this malacological section. In 1865, together with a group of American malacologists, he founded (and financed) the American Journal of Conchology. This ended in 1872. In 1879 he started the ''Manual of Conchology; structural and systematic; with illustrations of the species'', volume 1, series 1. When he died, nine volumes of the first series had been published. From 1887 until 1888, his assistant was

Henry Augustus Pilsbry Henry Augustus Pilsbry (7 December 1862 – 26 October 1957) was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a cent ...

. Thereafter, Pilsbry continued as editor of the ongoing multi-volume ''Manual of Conchology''. The work was continued until 1935 when 45 volumes had been published. Tryon named more than 5,600 new species, and can be considered one of the most prolific malacologists. His important collection (more than 10,000 specimens) made the Academy of Natural Sciences of Philadelphia the center of malacological studies in the 19th century. The

freshwater snail Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs t ...

genus '' Tryonia'' is named in his honor.
