Born on April 2, 1849, near Portage in Livingston County, New York, Frank Stephens was the eldest of the four sons of Nelson and Julia (née Preston) Benson. During his early years, the family moved to the Midwest, farming in Michigan, Illinois, Missouri and Kansas. An interest in wildlife led him at age 22 to take some lessons in taxidermy. At age 24, he married Elizabeth Fowler, and in 1874 the couple moved to Colorado, where he studied taxidermy with ornithologist
Charles E. Aiken. Moving to California in 1876, he settled in Witch Creek, San Diego County, California, where he farmed and continued collecting, working regularly for the U. S. Biological Survey and the University of California's
Museum of Vertebrate Zoology (MVZ). In the early 1880s, Stephens collected in southwest New Mexico and Arizona for Aikens and for
William Brewster (ornithologist) of Harvard's
Museum of Comparative Zoology. He collected for
Donald Ryder Dickey and
C. Hart Merriam, among others. He was a collector for the U. S. Biological Survey's 1891
Death Valley Expedition. Stephens's wife Elizabeth died in January 1898, and he married Kate Brown in August 1898. She accompanied him on several collecting trips, including the 1907 expedition to southeastern Alaska sponsored by
Annie Montague Alexander. In her own right,
Kate Stephens became an authority on shells. Stephens was active both in the field and the study throughout his 60-year career. He is credited with collecting at least 45 type specimens. ==Death==
