Canton

Lincoln County · South Dakota
Erected by Chamber of Commerce and State Highway Commission, 1955

Ernest Lawrence was born in Canton on August 8, 1901, not in 1902 as the bronze has it, and Merle Tuve six weeks earlier, on June 27, 1901. The two grew up as best friends and tinkered with radios as teenagers. Lawrence built the cyclotron at Berkeley and won the Nobel Prize in Physics in November 1939; element 103, discovered at Berkeley in 1961, was named lawrencium for him. Tuve chaired Section T, formed in August 1940 to develop the proximity fuze, and was founding director of the Applied Physics Laboratory, its main laboratory from 1942.
