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.
