The biologist and groundbreaking U.S. sex researcher amassed a huge archive of about 14,000 films and videos beginning in 1947 known as the "Kinsey Collection," the Los Angeles Times reports.
The collection includes everything from art house erotica and sex-education titles to about 2,000 crudely made stag party films from the 1920s through the 1960s that pre-date adult movie theaters, X-rated DVDs and online porn Web sites.
The racy stuff was kept locked away in a converted bowling alley near the Bloomington, Ind., campus for decades until the Kinsey Institute for Research in Sex, Gender and Reproduction moved it to a more modern facility.
The pornographic materials were not acquired at taxpayer expense, Kinsey Institute employees said. Kinsey, author of "Sexual Behavior in the Human Female," died in 1956.
"Kinsey had relations with police departments all over the country," IU film archivist Rachael Stoeltje told the Times. They would send him copies whenever they confiscated (such films). They're all amateur, all illegally made, all with bad lighting, but real gems. They're unique because this doesn't exist anymore."
