The Roy L. Brooks Distinguished Lecture Series was established to bring an African American scholar of distinction or promise to campus. The award is named after Professor Roy L. Brooks, who has been a long-standing member of our community; an award-winning and engaging teacher; a prolific author of original scholarship; and a distinguished member of the legal profession and community. This year's Roy L. Brooks Distinguished Lecture Series will feature Professor Brooks himself, as he prepares to retire after 47 years of teaching. The Library of Congress recognizes Professor Brooks as a distinguished scholar both in the United States and internationally. Professor Brooks is published by prestigious presses, including Harvard, Yale, Princeton, Cambridge, the University of California, and NYU. His books span various genres, including monographs, casebooks, textbooks, and even an anthology. Twenty of his books are held by 4,457 libraries, academic institutions, and learned societies worldwide. Join us for Professor Brooks' talk, titled "Living Memoir: Roy L. Brooks," in which he will discuss his life and legacy of scholarship. Professor Brooks will highlight several prominent themes within his literary works that have significantly influenced analyses of social justice, legal theory, and democratic theory. He will share how his innovative perspectives are deeply rooted in his personal life experiences, including the racially diverse middle-class neighborhood in which he was raised not far from Yale University. He will discuss his interdisciplinary studies in law, philosophy, history, sociology, political science, and anthropology; and his classmates at Yale Law School.
