Lawrence Otis Graham, 59, Dies; Explored Race and Class in Black America

Lawrence Otis Graham was born in Manhattan on Dec. 25, 1961, the son of Richard Graham, a real estate developer, and Betty (Walker) Graham, a social worker. His family soon moved to suburban Mount Vernon, just north of New York City. They moved further north, to White Plains, in 1967 — the same year, Mr. Graham later noted, that the film “Guess Who’s Coming to Dinner,” in which a white woman introduces her supposedly liberal parents to her new Black fiancé, played by Sidney Poitier, was released.
