Grandson of Ridley's founding Headmaster, Dr. J.O. Miller, ‘Tony’ Cassels was the Mason Gold Medal winner in 1936. He had an abiding interest in Ridley's affairs, as captain of the Ridley Fund in the 1930's, as president of the Ridley College Old Boys Association in the 1960's, and as an influential member of the Board of Governors. His wide-spread interests outside of the school included the 48th Highlanders Regiment, the Red Cross, the National Ballet of Canada, the Argonaut Football Club, the Ontario Historical Society, and the family law firm. He died in 1981. A ‘Tony Cassels Scholarship Fund’ was established that year, and the major debating trophy bearing his name perpetuates the memory of this outstanding Ridleian.
