J. Robert Oppenheimer was an American theoretical physicist. He was director of the Manhattan Project's Los Alamos Laboratory during World War II and is often called the "father of the atomic bomb".

Max Born was a German-British physicist and mathematician who was instrumental in the development of quantum mechanics. He also made contributions to solid-state physics and optics and supervised the work of a number of notable physicists in the 1920s and 1930s. Born was awarded the 1954 Nobel Prize in Physics for his "fundamental research in quantum mechanics, especially in the statistical interpretation of the wave function".
Solvay Conference, 1927. Born is second from the right in the second row, between Louis de Broglie and Niels Bohr.
