Leslie Clarence Dunn

Leslie Clarence Dunn (November 2, 1893 in Buffalo, New York – March 19, 1974) was a developmental geneticist at Columbia University. His early work with the mouse T-locus and established ideas of gene interaction, fertility factors, and allelic distribution. Later work with other model organisms continued to contribute to developmental genetics.

Biography Dunn was born in Buffalo, New York, in 1893, to Clarence Leslie Dunn and Mary Eliza Booth Dunn. He earned a bachelor's degree from Dartmouth College in 1915.

Dunn was married to Louise Porter, a Smith College graduate, and the couple had two children, Robert Leslie Dunn (b. 1921) and Stephen Porter Dunn (b. 1928).
