Inspired by a 1965 talk in Houston by U.S. Solicitor General Archibald Cox, Houston lawyer Marvin Nathan took a job with the Civil Rights Division of the U.S. Department of Justice right out of law school, where he tried civil rights cases in the Deep South, starting in 1966.

Nathan didn’t leave a passion for civil rights behind after he left the DOJ for private practice in his hometown of Houston; he’s been an active member of the Anti-Defamation League for 30 years and was the national chairman of the ADL’s Civil Rights Committee from 2003 to 2009.
