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).
