Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Bowling
In 1948, bowling lanes were first built in the ground floor of the West Wing of the U.S. Presidential residence, the White House, as a birthday gift for then President Harry S. Truman, in the location of the 2010s White House Situation Room. The lanes were moved to the Old Executive Office Building in 1955 to make way for a mimeograph room.
