Niels Bohr
Born in Copenhagen, Denmark on October 7th, 1885. He got his PhD in physics from the University of Copenhagen in 1911.
Bohr worked with Ernest Rutherford where they developed a model of atomic structure and helped to establish the validity of quantum theory.
At a conference held in Washington in January, 1939, he explained the possibility of creating nuclear weapons. After working with Enrico Fermi and Leo Szilard, Bohr showed that only the isotope uranium-235 would undergo fission with slow neutrons. He continued his research after Denmark was invaded by the German army. He escaped to Sweden in 1943 with the help of the British Secret Service. He tehn moved to the U.S. where he joined other scientist to develop the atom bombs dropped on Hiroshima and Nagasaki.
After the Second World War he returned to Denmark where he argued for strict controls on the manufacture of nuclear weapons. Nils Bohr died in Copenhagen on November 18th, 1962.
