The Mathematical Association of America (MAA) came into existence 100 years ago today, at a meeting in Columbus, Ohio. The founding members chose the icosahedron as the symbol for the association.
This stained-glass rendering of the MAA icosahedron is in the lobby of the Edgar H. Vaughn Building, named for the grandfather of James Vaughn, president of the Vaughn Foundation, a major contributor to the 1978 fund to purchase the building to serve as MAA headquarters in Washington, D.C.
