One of the leading civil rights attorneys in the post-World War II (1941-1945) period, Greenberg took on countless cases, many before the Supreme Court, aimed at breaking down legalized racial segregation in the United States.
The son of Eastern European Jewish immigrants, Greenberg grew up in New York City. After graduation from Columbia University and a tour in the Navy (including participation in the Iwo Jima landing), Greenberg entered Columbia Law School. While there, he developed his lifelong interest in civil rights law

Greenberg also appeared before the Supreme Court dozens of times to argue against race discrimination in housing, public accommodations, and employment. His most important work, however, was to dismantle segregation in the U.S. educational system, first in higher education and eventually throughout the system. He played a significant role in Brown v. Board of Education
