In Canton, South Dakota, Ernest Orlando Lawrence was born on the American prairie. He would invent the cyclotron, a revolutionary particle accelerator that earned him the 1939 Nobel Prize in Physics. His work on uranium-isotope separation proved crucial to the Manhattan Project, and he founded two premier research institutions: Lawrence Berkeley and Lawrence Livermore National Laboratories.
