His team at Los Alamos Laboratory tested the world’s first nuclear weapon on July 16, 1945. A few weeks later, the United States dropped atomic bombs over the Japanese cities of Hiroshima and Nagasaki, resulting in hundreds of thousands of deaths. Oppenheimer expressed opposition to the creation of the more powerful hydrogen bomb, which the U.S. government tested in 1952. In 1954, an investigation by the House Un-American Activities Committee alleged he was disloyal to the United States. Oppenheimer lost his security clearance and was barred from engaging in government-sponsored research. This portrait was taken by Lisette Model, who was a member of the New York Photo League, which organized photography competitions and exhibitions. Some members used their photography to raise awareness of political and cultural issues. It too came under government scrutiny as a potentially subversive organization. 📸: "J.
