Berl Kutchinsky
Berl Kutchinsky (1935 – 1995) was a Danish Professor of Criminology at the University of Copenhagen. He became internationally famous for his studies in the public health effects of pornography. He was based in Denmark, which in 1969 became the first country to legalize hardcore pornography Sweden followed suit in 1970, and West Germany in 1973. Kutchinsky was therefore in a unique position to study the effect of pornography on a massive scale. Over the next two decades Kutchinsky carried out extensive research into crime statistics in the three countries. His findings were that increased availability of pornography had  not led to an increase in sexual violence. He found that the incidence of certain sex crimes had in fact fallen, including rates of child sexual abuse in Denmark. His first work on the subject, "Studies on Pornography and sex crimes in Denmark" (1970), was a scientific report ordered by the United States' President's Commission on Obscenity and Pornography. It found that the legalizing of pornography in Denmark had not (as had been expected) resulted in an increase in sex crimes. In 1980 he helped to draft the law which banned child pornography in Denmark; after which according to  him, "Child porn has largely disappeared from Denmark." Berl Kutchinsky's last book, "Law, pornography, and crime: The Danish experience", was edited by his colleague Annika Snare and published posthumously in 1999.
