Japanese physicist Yoshio Nishina (1890-1951, left) in front of a blackboard with Danish physicist Niels Bohr (1885-1962, right). Bohr was awarded the 1922 Nobel Prize for Physics for his work on the structure of the atom. He said that electrons could only occupy discrete levels around an atomic nucleus. This explained the spectrum of hydrogen. He also worked on the atomic bomb project during World War II. Nishina is known as 'the founding father of modern physics research in Japan'. His research covered cosmic rays and particle accelerator development. He independently detected what turned out to be the muon in cosmic rays and discovered the uranium-237 isotope. Photographed in 1937.
