Memorable Manitobans: Frederick Stephen Mannix (1881-1951)


Born on a farm near Stonewall on 3 February 1881, son of George Charles Mannix (1845-1934) and Frances Bunn (1849-1918), he became one of Canada’s most successful pioneer contractors. In 1898, at age 17, he set out with a horse and slip to construct railroad grade in the Rural Municipality of Rockwood and the Rural Municipality of Woodlands. Moving to Edmonton, Alberta in 1904, then to Calgary in 1914, he founded the Fred Mannix Company in 1936 which became one of the largest heavy construction firms in the country, responsible for the building of much of western Canada’s infrastructure. His son Frederick Charles Mannix (1913-1995) built the company into an international conglomerate of over 100 companies. He also farmed and ranched. Retiring in 1943, he died at Calgary, Alberta on 14 July 1951.
