Additional information

Albert Champion founds new company in 1908 to rival Champion Ignition Co.

Champion Early History, in brief

Albert Champion was born in France in 1878. By 1899, Champion came to America to compete in a series of bicycle and motorcycle races. He had brought several bicycles and motorcycles from France, but found the parts very hard to locate in the United States. Champion began making spark plugs to help pay bills and cover expense and sold them to friends in Boston.

In 1900, Champion immigrated to America. By 1904, Champion moved to Flint, Michigan where he founded Champion Ignition Company for the manufacturing of spark plugs and dynamo's. With the help of investors, Champion was able to turn his motorcycle and automobile racing hobbies into a successful business. Unfortunately, problems with the investors lead to a break up in 1905. Champion soon found himself without a company. The investors continued to manufacture the spark plugs under the Champion name, but Champion himself was removed.

In 1908 with the backing of the Buick Motor Co., Champion began a new company called the AC (Albert Champion) Spark Plug Company and he was appointed president. In 1916 Alfred P. Sloan formed United Motors Corp. (soon to become GM) and eventually acquired Buick and AC Spark Plug.
