American geologist and petroleum engineer Ralph Arnold (1875-1961) was born in Marshalltown, Iowa, on April 14, 1875. His father, Delos Arnold (1830-1909), was a lawyer and Iowa state senator who became interested in the study of fossils after the discovery of crinoids fossils in LeGrand, Iowa. The Arnolds moved to Pasadena, California, in 1886, and Ralph attended both Pasadena High School and Throop Polytechnic School (now the California Institute of Technology) before receiving a B.A. in geology and mining from Stanford in 1899. He continued at Stanford to complete an M.A. (1900) and Ph.D. (1902) in geology and paleontology. In 1899, Arnold married Frankie Winninette Stokes. The couple had two daughters, Winninette, who married chemist Richard M. Noyes, and Elizabeth (McKee).
