Herbert Girton Deignan

Herbert Girton Deignan (December 5, 1906 – March 15, 1968) was an American ornithologist who worked extensively on the birds of Thailand.

He returned to Chiangmai to take back his position and stayed from 1935 to 1937 during which time he amassed a large collection of birds for the United States National Museum (USNM).

Deignan became a member of the American Ornithologists' Union in 1923 and became a Life fellow in 1946 going on to serve as Secretary from 1959 to 1961.

He published taxonomic revisions, collection catalogues and descriptions of birds from various parts of the world, especially Southeast Asia.

[2] Acheilognathus deignani was named by Hugh McCormick Smith in 1945, in honor of Deignan, who had collected the type specimen.
