The EAA was founded in 1953 by veteran aviator Paul Poberezny along with other aviation enthusiasts. The organization began as more or less a flying club. Paul Poberenzy explains the nature of the organization's name, "Because the planes we flew were modified or built from scratch, they were required to display an EXPERIMENTAL placard where it could be seen on the door or cockpit, so it was quite natural that we call ourselves the "Experimental Aircraft Association". Homebuilding is still a large part of EAA, but the organization has grown over the years to include almost every aspect of aviation and aeronautics. EAA's first home was in the basement of the Poberezny home. In the early 1960s, the association's first headquarters was built in the Milwaukee suburb of Franklin. That was the headquarters for the organization until 1983, when EAA combined its headquarters and fly-in site in Oshkosh, Wisconsin. The EAA Aviation Center also includes the EAA Aviation Museum, with more than 200 aircraft, approximately 130 of which are on display at any given time
