American physicist, winner of the 1939 Nobel Prize for Physics for his invention of the cyclotron, the first particle accelerator to achieve high energies.
Lawrence earned his Ph.D. at Yale University in 1925. An assistant professor of physics at Yale (1927–28), he went to the University of California, Berkeley, as an associate professor and became full professor there in 1930.
Lawrence first conceived the idea for the cyclotron in 1929. One of his students, M. Stanley Livingston, undertook the project and succeeded in building a device that accelerated hydrogen ions (protons) to an energy of 13,000 electron volts (eV). Lawrence then set out to build a second cyclotron; when completed, it accelerated protons to 1,200,000 eV, enough energy to cause nuclear disintegration. To continue the program, Lawrence built the Radiation Laboratory at Berkeley in 1936 and was made its director.
One of Lawrence’s cyclotrons produced technetium, the first element that does not occur in nature to be made artificially. His basic design was utilized in developing other particle accelerators, which have been largely responsible for the great advances made in the field of particle physics. With the cyclotron, he produced radioactive phosphorus and other isotopes for medical use, including radioactive iodine for the first therapeutic treatment of hyperthyroidism. In addition, he instituted the use of neutron beams in treating cancer.
During World War II he worked with the Manhattan Project as a program chief in charge of the development of the electromagnetic process of separating uranium-235 for the atomic bomb. In 1957 he received the Fermi Award from the U.S. Atomic Energy Commission. Besides his work in nuclear physics, Lawrence invented and patented a colour-television picture tube. In his honour were named Lawrence Berkeley Laboratory at Berkeley; Lawrence Livermore National Laboratory at Livermore, Calif.; and element 103, lawrencium.
He has been remembered as a "father of big science", for his involvement in organizing enormous, collaborative, mega-scale scientific projects.
He died 27 August 1958.
