This prize honors the memory of Michael R. Bennett, who joined the faculty at the University of Pittsburgh in 1974, coming from UCLA, but died unexpectedly in 1979 at the age of 35. He specialized in formal semantics and taught in a wide spectrum of philosophical areas. Richmond Thomason wrote that Michael would be remembered: "for his sensitivity to the problems of students and his concern for people, as well as for his profound dedication to philosophy."
The prize is awarded to a graduate student paper that is found to be of extraordinary quality. Because the standards for the award are high, if no essay is judged to meet them, the award is not given that year. Below is a list of past recipients, many of whom have gone on to extraordinary careers in philosophy.
