Ivan Graeme Ferguson, CM (born 7 October 1929 in Toronto, Ontario) is a Canadian filmmaker and inventor who co-invented IMAX. Ferguson was appointed a Member of the Order of Canada in 1993. He graduated from the University of Toronto with a bachelor's degree.
Graeme Ferguson was one of three co-founders of IMAX Corporation and thereby one of the creators of the IMAX. A film-maker from his childhood in the 1930s, he was still making films in 2010, with an executive producer credit on Hubble 3D. In 1971, Ferguson produced, directed and shot North of Superior, the first official IMAX film, which is still shown on IMAX screens.
Ferguson is also notable because of his involvement a landmark 1983 lawsuit brought by his ex-wife, who had been part of the founding team of IMAX. The claim involved a series of oppressive acts by Ferguson and his colleagues including a resolution to discharge her from the company and being pressured to sell back her shares. Brooke JA writing for the Court of Appeal found that the acts were tantamount to oppression and the resolution was barred. The court found that majority shareholders owe a duty of fairness to minority shareholders. Ferguson v. Imax Systems Corp. (1983), 43 O.R. (2d) 128 (C.A.).
