While a student at City College of New York, Libsohn joined the Film and Photo League as a self-taught photographer who earned his living documenting paintings. Then, in 1936, he cofounded the Photo League with Sid Grossman. Libsohn taught several technique classes, led numerous production groups, served as exhibition committee chair (1939, 1945–47, 1948), wrote and edited for League publications, and exhibited his photographs in several member shows, including "This Is the Photo League" (1948–49). From 1940 to 1943 he was a staff photographer for Look magazine and his work also appeared in U.S. Camera Annual (1939, 1941) and Social Work Today (1941). In 1938 he completed Food for New York, a photographic essay commissioned by the Federal Art Project (FAP) to document unsanitary food-handling practices in New York's outdoor locations. He also worked for Roy Stryker's Standard Oil project (1944–50). After the Photo League disbanded, Libsohn freelanced for magazines such as Fortune and Ladies' Home Journal. His photographs were included in the "Family of Man" exhibition at the Museum of Modern Art (1955). He later taught photography to disadvantaged youth at Princeton University's Summer Program.
