Paul Allen, whose fortune was made through Microsoft though he had long since ceased to be an active participant in the company, was a major force in Seattle politics. He attempted a voter initiative to build the Seattle Commons, a huge park in South Lake Union and the Cascade District, and even offered to put up his own money to endow a security force for the park, but it was defeated at the polls. (Allen then became the leader of the movement to redevelop this same area as a biotech center.) He did get a football stadium for the Seattle Seahawks through a successful statewide ballot initiative, and founded the Experience Music Project (originally intended as a Jimi Hendrix museum) on the grounds of Seattle Center.
