World War II Headlines

The Manhattan Project dominated World War II history in early 1944. For details, see the headlines below.

U.S. brigadier general Leslie Groves leads the Manhattan Project: U.S. brigadier general Leslie Groves named the Manhattan Project and was a driving force behind the creation of the first atomic bomb. He chose the sites for research and materials production and put physicist J. Robert Oppenheimer in charge of the scientific laboratory. Groves was intelligent and highly organized, and although his arrogance offended some scientists, he worked well with Oppenheimer. Groves maintained high security at the Los Alamos, New Mexico, facility, having mail censored, long-distance calls monitored, travel restricted to within 100 miles, and contact with those on the outside limited.

American physicist J. Robert Oppenheimer directs Los Alamos team assigned to the Manhattan Project: The presence of brilliant American physicist J. Robert Oppenheimer attracted scientists from all over the world to the remote New Mexican desert to work on the Manhattan Project. Oppenheimer directed the scientific team headquartered at Los Alamos. Although he suffered from periods of depression, he personally helped resolve or control conflicts that inevitably rose among the diverse international group. He, like most Los Alamos scientists, was dedicated to ending war for all time. After atomic bombs were used at Hiroshima and Nagasaki, Oppenheimer was appalled at the civilian deaths. Following the war, as chief advisor of the United States Atomic Energy Commission, he lobbied for the international control of atomic energy.

In January and February 1944, the United States attacked Frankfurt, Nazi Germany, and a Japanese island. Learn more about these and other operations in the next section.
