Veteran engineer who alongside his work with the Repco engine, became well known for his Vincent motorcycle engine and his Velocette motorcycle design. He started work in 1922 at Crankless Engines, before owning and running a motorcycle workshop. In 1931, he came over to England to initially take part in a Round-the-World event, but stayed in the UK to work for Philip Vincent and then for Velocette. Between 1943 and 1949, he worked for Vincent, before returning to Australia, where he concentrated on technical journalism, and wrote a number of books. Approached by Jack Brabham to especially design an engine for him, he developed the Repco, which won the World Championship in 1966. Awarded an MBE in the New Year's Honours of 1976, Irving continued to be involved with engines in his workshop in Warrandyte, near Melbourne, until weeks before his death. There are still a few motorcycle races in his name, in honour today.
