Dr. Charles Henry Turner uncovered new species; contributed several of the early anatomical studies of crayfish and bird brains; developed new methodologies (several of which are still used today); contributed literature reviews; clarified several behavioral and methodological issues in the areas of tropisms, memory, and behavioral ecology; and was the first to provide experimental evidence that certain insects can hear airborne sounds. He was also a leader in the early struggle for civil rights. This volume contains biographic information and illustrations, a broad selection of Turner's papers, both on behavioral science and race relations, and bibliographic information.
