Gerald Vincent Bull, engineer and ballistics expert (born 9 March 1928 in North Bay, ON; died 22 March 1990 in Brussels, Belgium). He studied at the University of Toronto’s Institute for Aerospace Studies. At the time, he was the youngest person to ever receive a PhD from the university. He was involved in some of Canada’s most advanced experimental defence projects. Later in his life, Bull was convicted of breaking an international arms embargo against apartheid South Africa. He spent his life perfecting artillery systems; some of his designs could launch payloads into space. He was assassinated during the development of a space gun for Iraq.
