A friend of the Wharton Esherick family, Susan R. Hinkel began writing a biography about Wharton Esherick, the influential sculptor and craftsman, although she never finished the book. The Susan Hinkel research files on Wharton Esherick, 1989-2000, consist of materials that Hinkel compiled by while preparing the unfinished biography. The files are organized by subject and include chapter drafts, research-related correspondence, clippings and ephemera, and various other secondary-source materials. Of special interest are transcripts of oral histories that Hinkel conducted for the book, in particular interviews with Ruth Esherick and Mansfield "Bob" Bascom.
