Francis Bertody Sumner (1874-1945), was a professor of Biology, and ichthyologist, at Scripps Institution of Oceanography. Sumner's name will probably remain most closely and most favorably associated with his longest research, the analysis of speciation in mice of the genus \"Peromyscus\", but most of his separate studies were conducted on fishes. He made significant contributions on the mechanism of color change in fishes and his research on color adaptation in flounders opened a new field. 1936.
