Kenneth Zeller (died June 1985) was a teacher and librarian in Toronto, who was employed by Davisville Public School, Williamson Road Junior Public School and Western Technical-Commercial School. He was the victim of a homophobic hate crime when he was beaten to death by five youths in Toronto's High Park. Five young offenders were convicted and sentenced to prison.
The crime received media coverage and was the subject of a play called Steel Kiss, written by Robin Fulford and produced by Buddies in Bad Times theatre. John Greyson also produced a movie called The Making of Monsters. It was never released for general viewing. The incident also spurred the Toronto District School Board into implementing a program designed to eliminate discrimination based on sexual orientation.
