Frits Bernard (August 28, 1920 in Rotterdam – May 23, 2006) was a Dutch psychologist, sexologist, homosexual activist, and pro-paedophile activist. Bernard founded the Enklave kring, which led to the International Enclave Movement, in the late 1950s, and has been described as a founder of the entire pro-pedophile movement. He was also an author, a member of the Association for the Advancement of Social Scientific Sex Research's board of directors, and founder of the Bernard Foundation.
At seven, Bernard moved to Spain to attend the Internationale Duitse School in Barcelona. He returned to the Netherlands during the second world war, where he studied at the Universiteit van Amsterdam and the Catholic University of Nijmegen. In the late fifties, Bernard joined the COC, a Dutch LGBT organization. He argued for pedophilia in the COC's publication, Vriendschap, using the pseudonym "Victor Servatius." He became active in the Dutch Society for Sexual Reform around 1970.
