The end of World War II brought with it the end of the Manhattan Project. The Atomic Energy Act was signed into law on August 1, 1946, creating the Atomic Energy Commission (AEC). It went into effect on January 1, 1947. Los Alamos became the Los Alamos National Laboratory, under AEC direction. The Chicago Metallurgical Laboratory was succeeded by the Argonne National Laboratory. A number of the African-American scientists and technicians continued to work at the Argonne National Laboratory, while others sought jobs in teaching and industry.
