Jack Greenberg, a lawyer who became one of the nation’s most effective champions of the civil rights struggle, leading the NAACP Legal Defense and Educational Fund Inc. for 23 years and using the law as a weapon in its fight for racial justice before the United States Supreme Court, died on Wednesday at his home in Manhattan. He was 91.

Mr. Greenberg was the last surviving member of a legendary civil rights legal team assembled by Thurgood Marshall, the founding director-counsel of the legal defense fund and later the first African-American Supreme Court justice.
