Champion became interested in gas-combustion engines and car racing while he was in the USA. In the summer of 1904 he moved back to France and won the national 100-kilometer motor-pace race on the Parc des Princes outdoor cement track. He retired from cycling at the end of the summer. He remained in Paris to work in car factories, including one founded by his friend Edouard Nieuport, who manufactured Nieuport spark plugs and magnetos, credited with helping drivers win the biggest road races. Champion returned to America and incorporated the Albert Champion Company in June 1905 in Boston's South End, in the landmark
Cyclorama Building, to import French electrical parts, including Nieuport components. Champion presided as president of the Albert Champion Company with partners Frank D. Stranahan as treasurer and younger brother Spencer Stranahan as clerk. By 1907 The Albert Champion Company was manufacturing porcelain spark plugs with the name Champion stamped on the side, Robert Stranahan, the youngest of the Stranahan brothers, finished his classes at Harvard, ahead of his class of 1908, and went to work in the stockroom. Late in the summer of 1908, Champion met William Durant at Durant's Boston Buick dealership. Durant, impressed with the spark plugs, persuaded Champion to move to Flint and supply his spark plugs to Flint. A week after Champion arrived in Flint—accompanied by his wife, youngest brother Prosper Champion, and a dozen French compatriots—Durant incorporated General Motors and quickly purchased Cadillac and Oldsmobile motor companies. Champion incorporated the Champion Ignition Company, in Lansing, Michigan in October 1908. His first office was on the top floor of Buick factory 1. Champion's earlier partners, the Stranahan brothers, moved to Toledo, Ohio, and in 1910 incorporated the Champion Spark Plug Company in Wilmington, Delaware, as Nye documents. The Stranahans sued Albert Champion and his Champion Ignition Company over his name and the suit dragged on in federal district court. Champion finally settled out of court in 1922 and changed the name of his company to AC Spark Plug Company, after his initials, To this day, both names survive as
ACDelco (GM products) and Champion spark plugs sold by
Federal-Mogul. ==Personal life and death ==
