Alvin Ailey Jr. (January 5, 1931 – December 1, 1989) was an American dancer, director, choreographer, and activist who founded the Alvin Ailey American Dance Theater (AAADT). He created AAADT and its affiliated Alvin Ailey American Dance Center (later Ailey School) as havens for nurturing Black artists and expressing the universality of the African-American experience through dance.

A gay man, his work fused theater, modern dance, ballet, and jazz with Black vernacular, creating hope-fueled choreography that continues to spread global awareness of Black life in America. Ailey’s choreographic masterpiece Revelations is recognized as one of the most popular and most performed ballets in the world.

On July 15, 2008, the United States Congress passed a resolution designating AAADT a “vital American cultural ambassador to the World.” That same year, in recognition of AAADT’s 50th anniversary, then Mayor Michael Bloomberg declared December 4 “Alvin Ailey Day” in New York City, while then-Governor David Paterson honored the organization on behalf of New York State.
