Based upon my memory of auto history read:
Famed auto racer Albert Champion did create the Champion Spark Plug, but later had a falling out with investors, and lost control of the company.
Champion went on to work with Buick, leading to the establishment of automotive electronics manufacturer, AC (Albert Champion), now GM division AC Delco.
Perhaps 'our' Albert Champion has a relationship with AC.
