This bookplate for the library of the Institute for Sex Research (ISR) was designed by Robert Latou Dickinson (1861-1950), a gynecologist and noted pioneer of sex research in the United States. Dickinson's studies, including A Thousand Marriages (1931) and The Single Woman (1934), were based on more than 50 years in private practice with over 5000 New York City patients, and had a significant influence on later work done by physicians, gynecologists, marriage counselors, students of fertility and other clinical researchers. Kinsey personally credited Dickinson as one of the original sources of inspiration for his own work. Upon learning of Kinsey's research, Dickinson reportedly exclaimed, "At last! At last! This is what I have been hoping and praying for all these years." Their friendship and enthusiasm for each other's work prompted Dickinson's offer to design a bookplate for Kinsey's new research group. This final design was approved in 1946 and the "Inc." was added shortly thereafter with the incorporation of the Institute in 1947.
