On this date, the American biologist and professor of entomology and zoology Alfred Charles Kinsey was born in Hoboken, New Jersey. In 1947, he founded the Institute for Research in Sex, Gender and Reproduction at Indiana University, now called the Kinsey Institute for Research in Sex, Gender, and Reproduction. Kinsey’s research on human sexuality profoundly influenced social and cultural values in the United States and many other countries.
Kinsey is generally regarded as the father of sexology, the systematic, scientific study of human sexuality. He initially became interested in the different forms of sexual practices around 1933, after discussing the topic extensively with a colleague, Robert Kroc. It is likely that Kinsey’s study of the variations in mating practices among gall wasps led him to wonder how widely varied sexual practices among humans were.
The Kinsey Reports — starting with the publication of Sexual Behavior in the Human Male in 1948, followed in 1953 by Sexual Behavior in the Human Female — reached the top of bestseller lists and turned Kinsey into an instant celebrity. Based on his research, Kinsey concluded that:
The only unnatural sex act is that which you cannot perform.
During this work, Kinsey developed a scale classifying sexual behavior, now known as the Kinsey Scale. The scale ranges from 0 to 6, where 0 is exclusively heterosexual and 6 is exclusively homosexual; a rating of 7, for asexual, was added later by Kinsey’s associates. It is important to note that Kinsey said in both the Male and Female volumes that it was impossible to determine the number of persons who are “homosexual” or “heterosexual”. It was only possible to determine behavior at any given time.
The 2000s have seen renewed interest in Kinsey. The musical Dr. Sex focuses on the relationship between Kinsey, his wife, and their shared lover Wally Matthews (based on Clyde Martin). The play—with score by Larry Bortniker, book by Bortniker and Sally Deering—premiered in Chicago in 2003, winning seven Jeff Awards. It was produced off-Broadway in 2005. The 2004 biographical film Kinsey, written and directed by Bill Condon, stars Liam Neeson as the scientist and Laura Linney as his wife. In 2004 as well, T. Coraghessan Boyle’s novel about Kinsey, The Inner Circle, was published. The following year, PBS produced the documentary Kinsey in cooperation with the Kinsey Institute, which allowed access to many of its files. Mr. Sex, a BBC radio play by Steve Coombes concerning Kinsey and his work, won the 2005 Imison Award.
