The Bronx Documentary Center has a great online exhibit of the photography of Leo Goldstein. Goldstein photographed East Harlem in the 50’s and captured, in black and white, the gritty world that awaited many Puerto Ricans who moved to New York in the post-war era.
Goldstein belonged to The Photo League which was targeted by the FBI in the postwar witch hunt period as a subversive organization and forced to disband in 1951. However, Leo and a number of former members continued to meet at each other’s homes on a round-robin basis to show and critique their work.
