Nuclear energy

Three years of preparation which led up to achievement, with Ernest T. S. Walton in 1932, of the first artificial transmutation of elements by accelerated protons, and the joyous reactions of his colleagues at the Cavendish Laboratory. With a three month grant from the Rockefeller Foundation, in 1933 visits with Robert Van de Graaff in Boston, Merle Tuve in Washington, Charles Lauritsen in Pasadena and Ernest O. Lawrence in Berkeley. In 1937, on his second American trip, noticed that the "sealing wax and string" at University of California at Berkeley had been replaced by engineering. Effect of influx of German refugee physicists. Rutherford's attitude toward a cyclotron at Cavendish because of Marcus Oliphant's low voltage ion source. Need for higher voltages and benefaction of a quarter million pounds from Lord Austin. Rutherford's complete control of Laboratory, the changing role of Cavendish over time; impact of the discovery of fission in England; effects of the war on nuclear physics and the differences in postwar planning and funding of research. Also prominently mentioned are: Niels Henrik David Bohr, James Chadwick, Ralph Howard Fowler, Petr Kapitsa; Cavendish Laboratory, European Council of Nuclear Research, Dept. of Physics at University of California Berkeley, and University of Oxford.
