William vanden Heuvel, a former diplomat, lawyer and adviser to Robert F. Kennedy, died Tuesday in New York City from complications of pneumonia at the age of 91. Vanden Heuvel fought for civil rights, including during his time at the Justice Department from 1962 to 1964. He also advocated for better conditions for incarcerated people, calling on the media to help shine a light on the failures of the criminal justice system. In 1972, vanden Heuvel wrote, “The right to know in a democracy frequently depends on the demand to know by the media.” He is survived by his wife and his two daughters, including Katrina vanden Heuvel, publisher and former editor of The Nation.
