Sydney Hugh ("Syd") de Kantzow (9 November 1914 – 21 November 1957) was the Australian co-founder of Cathay Pacific Airways with American Roy Farrell. De Kantzow, the son of Charles Adolphus de Kantzow, was born to a family of Polish/Swedish origin and grew up in the Sydney suburb of Roseville, New South Wales. He served during World War II as a pilot for the Royal Australian Air Force. Both de Kantzow and Farrell were ex-air force pilots who had flown The Hump, a route over the Himalayan Mountains. It was said that Madame Chiang Kai-shek always asked for him personally as her pilot. He was awarded the Order of the Cloud and Banner personally by her for his services with CNAC and the Burma Star for his services in respect to the relief aid program.
