Ernest Orlando Lawrence (1901–58) was an American physicist who won the 1939 Nobel Prize in Physics for inventing the cyclotron. This breakthrough particle accelerator revolutionized nuclear physics and enabled high-energy experimentation.
Born in Canton, South Dakota, he studied at St. Olaf College and the University of South Dakota before earning his PhD in physics from Yale University in 1925. He joined the University of California-Berkeley, in 1928 and became a full professor in 1930. In 1936, he was named the first director of the Radiation Laboratory.
In 1930, Lawrence invented the cyclotron, allowing scientists to accelerate nuclear particles and achieve major breakthroughs in both research and medical treatment. His work contributed significantly to the Manhattan Project, especially in uranium-isotope separation.
His legacy is documented in An American Genius: The Life of Ernest Orlando Lawrence, Father of the Cyclotron (1968) by Herbert Childs.

For it goes without saying that this great recognition at this time will aid tremendously our efforts to find the necessarily large funds for the next voyage of exploration farther into the depths of the atom.
