A first-generation New Yorker, Rosenblum learned about the Photo League while a student at City College of New York (1937–38). He soon joined, remaining an active member of the group until 1950. He worked on two major projects with Sid Grossman: the Pitt Street Document and the East Side Group (1938). He became the League's office secretary in 1938, then served as Photo Notes editor (1940), president (1941–42 and 1946–47), and vice president (1948–49); he taught courses in 1942 and 1947. Rosenblum exhibited his work often at the League and was the subject of several solo exhibitions outside the League, including shows at the American Red Cross in London (1944) and the Brooklyn Museum (1949). During World War II, he served in the U.S. Army Signal Corps and later the Army Pictorial Service, receiving numerous decorations for his service as a war photographer. After the Photo League disbanded, Rosenblum continued to exhibit widely. He taught photography at Brooklyn College (1946–83), the Yale Summer School of Music and Art (1952–77), and the Cooper Union (1956–65). Over the years, he and his wife, the historian of photography Naomi Rosenblum, collaborated on exhibitions and articles about the medium. Rosenblum has been awarded grants from the National Endowment for the Arts (1976) and the New York State Council on the Arts and the Guggenheim Foundation (1980). He received a Lifetime Achievement Award from the International Center of Photography in 1998.
