Ralph Ellison

A monument outside 730 Riverside Drive in Harlem, N.Y. — writer Ralph Ellison's longtime home — commemorates his life and his work. The marker, and many biographical sources, list his birth date as being 1914. But in fact, he was born a year earlier.

Still, events in Oklahoma City — his birthplace — and New York City, where he spent most of his life, are celebrating the centennial of his birth this year.
