I first met Calvin Massey in person in 1994, when I joined the U.C. Hastings faculty. However, I knew of and admired Calvin’s scholarship long before that. Six years earlier, I was a law student at the University of Chicago, and a student editor at the law review. In that role, I helped cite-check and edit a major article authored by Calvin, as well as a series of short responses by Calvin and other scholars, debating the meaning and scope of the Eleventh Amendment to the U.S. Constitution. I was struck then, and continue to be amazed, by the clarity, thoroughness, and intellectual rigor of this exchange, and especially Calvin’s contributions to it. I truly believe that these papers provide a model for what engaged, respectful, and careful scholarly debate should look like. They certainly provided an inspiration to me as I began my scholarly career, just as Calvin provided crucial mentorship during my early years at Hastings. In this brief essay I summarize this intellectual exchange, and explain why I think it epitomizes Calvin’s extraordinary strengths as a scholar, and as a gentleman.
