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

in Philadelphia.
In 1859, Tryon became a member of the
Academy of Natural Sciences
The Academy of Natural Sciences of Drexel University, formerly the Academy of Natural Sciences of Philadelphia, is the oldest natural science research institution and museum in the Americas. It was founded in 1812, by many of the leading natura ...
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 centu ...
. 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 which 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 ...
genus ''
Tryonia'' is named in his honor.
