Harlem civic leader, a former executive director of the New York Urban League and a retired justice of State Supreme Court in Manhattan. After finishing high school, he was a porter at Grand Central Terminal for seven years. Later, he worked as a skycap at La Guardia Airport while attending night classes at St. John's University. He graduated in 1946 and then received his law degree from the university. His law partnership with Thomas Weaver, Herbert Evans and Bruce Wright opened its doors on lower Broadway in 1956. Five years later, Representative Adam Clayton Powell became the chairman of the House Committee on Education and Labor and recruited Justice Wingate to be associate chief counsel. He then served as executive director of the Harlem antipoverty agency Haryou-Act, which stands for Harlem Youth-Associated Community Teams; associate director of the Citizens Crusade Against Poverty, and, from 1968 to 1975, executive director of the New York Urban League. With the support of Mr. Rangel, he was appointed a judge of Criminal Court of the City of New York in 1975. He served as a justice of State Supreme Court in Manhattan from 1982 until his retirement in 1985. Justice Wingate is survived by a daughter, Linda, of Arlington, Va.; two sons, Anthony, of San Francisco, and Livingston Jr., of Seattle, and a sister, Doris Wedderburn of Harlem.
