WW II & the 50s
In the popular imagination, post-war America was a period of wholesomeness and restraint. Think "Ozzie and Harriet" or "Leave it to Beaver." But it was during this period that Alfred Kinsey, a zoologist at Indiana University, published Sexual Behavior in the Human Male (1948) followed by Sexual Behavior in the Human Female (1953). Known as the Kinsey Reports, these studies drew on Kinsey’s unconventional research that reportedly included observing co-workers and other volunteers engaging in sexual activity. It was also during the '50s that William Masters, a physician, and Virginia Johnson, a psychologist, began their research on the nature of human sexual response.
