title: An unexpected admirer of Ladygina-Kohts.
abstract: Previously unknown correspondence between Nadya Nikolaevna Ladygina-Kohts, author of The Chimpanzee Child and the Human Child (1935), and Harry Harlow shows a reciprocal interest in, and admiration for, each other's work. In 1960 and 1961, they exchanged some 9 letters as well as numerous reprints and publications. The correspondence shows that Ladygina-Kohts and Harlow had been following each other's work for years and that Ladygina-Kohts's work may have been one of the major inspirations to Harlow's primate program.
