In the 1930s, a young reporter by the name of William Gottlieb set out to cover the boom of the jazz scene for the Washington Post, only to find the paper didn’t care to dispatch an official staff photographer. So Gottlieb, a self-taught photographer armed with his Speed Graphic and an ample supply of flashbulbs, took it upon himself to photograph the subjects of his interviews. Between 1938 and 1948, he documented the jazz scene in New York City and Washington, D.C., and created what eventually became some of history’s most iconic portraits of jazz greats. The Golden Age of Jazz gathers 219 of those, including Louis Armstrong, Ella Fitzgerald, Sarah Vaughan (who would have been 88 today), Billie Holiday, and Thelonious Monk, along with original text from the photographer contextualizing the images and their subjects.

On February 16, 2010, Gottlieb’s photographs entered the public domain and are now available online, courtesy of The Library of Congress, who also have rare footage of Gottlieb speaking about his photos.
