Pi Day was created by Larry Shaw in 1988 when he was at the San Francisco Exploratorium working as a Physicist. The initial celebration involved staff and the public walking around one of the circular spaces, and then consuming fruit pies. In March of 2009 the U.S. House of Representatives passed a non-binding resolution recognizing March 14 as National Pi Day.
