Jacobs did not invent the multi spark discharge ignition. That probably predates his birth. Earliest patent I can find that references more than one spark per ignition event was issued in 1939. It was both tube based and a non-contact electronic ignition system.
ok. maybe I should have said the first marketable capacitive discharge for the aftermarket auto world. slice and dice but it's my understanding that there wouldn't be an MSD box without Jacobs.
