The Diekhoff Award honors John S. Diekhoff, a distinguished scholar, teacher, mentor and administrator who served Case Western Reserve in several capacities during his tenure from 1956 to 1970: professor of English, chair of the Department of English, dean of Cleveland College, acting dean of the School of Graduate Studies and vice provost of the university.

The Diekhoff Award, established in 1978, recognizes outstanding contributions to the education of graduate students through advising and classroom teaching. The annual award is presented to two faculty members who epitomize what it means to teach graduate students: to connect them with experts in their discipline, engage them academically in a forthright and collegial manner, and actively promote their professional development. In 2009, the Diekhoff Award was expanded to recognize two additional full-time faculty members who excel in the mentoring of graduate students. A committee of Graduate Studies students reviews the nominations and recommends winners.
