Kinsey : A Biography by Jonathan Gathorne-Hardy
Alfred Kinsey was the twentieth century's first scientifically reputable and most influential researcher into sex. His Sexual Behaviour in the Human Male (The Kinsey Report), published in 1948, was an explosive bestseller, followed in 1953 by his even more radical statistics on female sexuality - both based on over 18,000 case histories. But Kinsey's exploration went much further than that. Bisexual, he experimented with many of the behaviours he was hearing about; and his wife and close colleagues experimented as well.
