Q: Question: Who founded Alfa Romeo? Passage:Glen Kidston competed in numerous motor races including the Monte Carlo Rally, Isle of Man TT motorcycle races, and Shelsley Walsh hillclimb. As a naval amateur he raced a Sunbeam motorcycle up the hill climb in Hong Kong and conducted speed trials on the sands, bringing the bike with him in his submarine which was patrolling the China Station. Kidston entered the 1929 Irish Grand Prix Eireann Cup at Phoenix Park but was narrowly beaten by the Alfa Romeo of former Russian Imperial Guard officer Boris Ivanowski. This was achieved at the expense of Britons Glen Kidston and Henry Birkin, whose Bentleys were second and third respectively. He also owned and raced the first Bugatti in the UK and entered the Le Mans 24-hour race in 1929 and 1930. On the second occasion he won the race, driving a Bentley Speed Six in partnership with Woolf Barnato, with the Bentley team delivering a 1-2-3-4 victory.
