Jack Greenberg (December 22, 1924 – October 12, 2016) was an American attorney and legal scholar. He was the Director-Counsel of the NAACP Legal Defense Fund from 1961 to 1984, succeeding Thurgood Marshall. 
He was involved in numerous crucial cases, including
. Brown v. Board of Education  In all, he argued 40  civil rights cases before the U.S. Supreme Court. 
He was Alphonse Fletcher Jr. Professor of Law Emeritus at
Columbia Law School, and had previously served as dean of  Columbia College and vice dean of Columbia Law School. He died on October 12, 2016.  
Greenberg was born into a
Jewish family in Brooklyn, New York on December 22, 1924.   
World War II, Greenberg served in the United States Navy and fought at Okinawa and Iwo Jima. Greenberg commanded a  landing craft in the invasion of Iheya Shima, one of the final campaigns of the war. During his service, he was disturbed by racial prejudice he perceived in the Navy, and was threatened with a court martial for shouting at a superior officer in defense of a black crewman that he felt was being mistreated.  
After an interruption due to his war service Greenberg graduated from
Columbia College with a B.A. in 1945. He further received an LL.B. from Columbia Law School in 1948, and an LL.D. from Columbia Law in 1984.  
Civil and human rights lawyer
Greenberg became the only white legal counselor for the
NAACP Legal Defense and Educational Fund ("LDF") in 1949, and, in 1961, succeeded Thurgood Marshall as LDF's Director-Counsel.
Greenberg recalled his earliest arguments before the Supreme Court, saying:
"It was like a religious experience; the first few times I was there I was full of awe. I had an almost tactile feeling. The first time I was in the Court, I wasn't arguing. I felt as if I were in a synagogue, and reached to see whether or not I had a
yarmulke on. I thought I ought to have one on." 
In addition to arguing
Brown v. Board of Education as co-counsel with Thurgood Marshall, other cases Greenberg argued include  , which ordered the end of segregated school systems "at once", and Alexander v. Holmes County Board of Education , Griggs v. Duke Power Company which outlawed basing employment and promotion decisions on the results of tests with a discriminatory impact. He also argued  (1972), Furman v. Georgia  in which the Court held that the death penalty as it was then applied was a violation of the "  cruel and unusual punishment" clause of the Eighth Amendment.
Greenberg was a founding member of the
Mexican American Legal Defense and Education Fund (MALDEF) and of Human Rights Watch.  
Greenberg was an adjunct professor at Columbia Law School from 1970–84, a visiting lecturer at
Yale Law School in 1971, and a visiting professor at College of the City of New York in 1977.
In 1982, he was appointed to co-teach
Julius L. Chambers' class on race law at Harvard Law School. The university declined to replace Greenberg with a black professor, so black students boycotted the class. When asked if he was frightened to pass through a group of protesters on his way to class the first day, Greenberg said, "No, I was on the beach at Iwo Jima."  
Greenberg left LDF in 1984 to become a professor and Vice Dean at
Columbia Law School. He served as Dean of Columbia College from 1989 to 1993. Greenberg's teaching interests include  constitutional law, civil rights, and human rights law, civil procedure, " Kafka and the Law", and South Africa's post- apartheid constitution. As of fall 2013, Greenberg still taught at Columbia Law School, and served as a senior director of LDF.
He was also a distinguished visiting professor at
University of Tokyo Faculty of Law in 1993-94 and at St. Louis University Law School in 1994, and a visiting professor at Lewis and Clark Law School in 1994 and 1996, at Princeton University in 1995, at the University of Munich in 1998, at Tokyo University in 1996 and 1998, at the University of Nuremberg-Erlangen in 1999-2000, and at Hebrew University in 2005.
Greenberg has varied intellectual interests: aside from several books on law and civil rights, including
Crusaders in the Courts, he has written a cookbook (  Dean Cuisine, with  Harvard Law School Dean James Vorenberg), and appeared as a panelist for a tasting of New York Times Oregon pinot noir. He also edited (Princeton: Princeton University Press, 2008) with two other scholars. Franz Kafka: The Office Writings
