Kilby's parents, James Lafayette and Sophronia Kilby, lived along the
Nolichuckey River in the north portion of
East Tennessee's hill country. The youngest of eight children, he was the first of his family to graduate from college. While studying at the
University of Arkansas, he worked part-time in the registrar's office at nearby
John Brown University. Clyde graduated in 1929, and the next year married Martha Harris, a mathematics teacher at JBU. They moved to Minnesota, where Kilby earned a master's degree in 1931 from the
University of Minnesota. In 1935, Kilby moved to
Wheaton, Illinois, where he became an assistant professor of English. In 1938, he earned his Ph.D. by correspondence from
NYU. He became chair of the English department at Wheaton in 1951, a post he retained until 1966. Dr. Kilby retired from teaching at Wheaton in 1981, and retired to
Columbus, Mississippi, his wife's hometown, where he died on October 18, 1986. In his honour, the Clyde S. Kilby Award for Inkling Studies was issued (one notable winner is
Colin Duriez), and also the Clyde S. Kilby Research Grant (
Diana Pavlac Glyer is a recipient). There is a Clyde S. Kilby Chair at Wheaton College (currently
Christina Bieber Lake). ==Lewis and Inkling scholarship==
