In 1949, when he was 24, Greenberg joined the Inc. Fund, which would later be called the NAACP Legal Defense and Educational Fund. He worked on some of the most important civil rights cases, including representing Martin Luther King, Jr. He also led the Fund's campaigns to help integrate the University of Alabama and the University of Mississippi. With others, he tried the Delaware and Topeka cases of Brown v. Board of Education. His memoir and history of the NAACP Legal Defense and Educational Fund is called Crusaders in the Courts: Legal Battles of the Civil Rights Movement.
Civil rights attorney and law professor Jack Greenberg. He was just out of law school--a white Jewish man from the Bronx when he joined the fledgling NAACP Legal Defense and Educational Fund (LDF). Greenberg took over the helm of the LDF from his mentor Thurgood Marshall when Marshall was appointed to the Federal Court of Appeals. During Greenberg's tenure there, the LDF litigated some of the watershed cases of the civil rights struggle. He has just published a memoir of his 35 years at the LDF.
