Billie Holiday (Eleanora Fagan Gough, Philadelphia, PA, April 7, 1915 – New York City, NY, July 17, 1959) was an American jazz singer and songwriter.

Nicknamed Lady Day by her loyal friend and musical partner Lester Young, Holiday was a highly original influence on jazz and pop singing. Her vocal style, strongly inspired by jazz instrumentalists, pioneered a new way of manipulating phrasing and tempo. Above all, she was admired for her deeply personal and intimate approach to singing.
