BOSTON (AP) — Malcolm X’s boyhood home in Boston has been added to the National Register of Historic Places. The 2 ½-story house is the only surviving residence associated with the slain civil rights leader’s formative years in Massachusetts. The National Park Service says the home was officially listed last month. The former Malcolm Little was a teenager in the 1940s when he came to live with his sister’s family at the home in the city’s Black Roxbury neighborhood. His sister’s family, which still owns the house, is hoping to turn it into a residence for graduate students studying Black history and civil rights.
