Harold Corsini was an American photographer.
Harold Corsini was born to Italian immigrants in New York City and began his career there as a freelancer. A photo he took when he was about 16, an aerial shot of football players, is archived in the George Eastman Collection in Rochester, New York. He assisted Arnold S. Eagle for three years as a photography teacher for the National Youth Administration. Corsini admired the work of Roy Stryker's Farm Security Administration photographers and aspired to the documentary style they practiced. He joined the Photo League in 1938, "the only free camera club in New York City", whose members were socially concerned photographers.
After a stint with Life magazine, in 1943 Corsini joined the Standard Oil documentary project under Roy Stryker, where he worked longer than any other photographer. In 1950, he accompanied Stryker to Pittsburgh, Pennsylvania and assisted him as head of the photographic department at the Pittsburgh Photographic Library. There he chronicled the city's first Renaissance, which included redevelopment of the Point and construction of Gateway Center.
