Does tragedy haunt certain families? According to AFP, Nicholas Hughes, the son of poets Sylvia Plath and Ted Hughes, hung himself today in Alaska, 46 years after his mother’s suicide. Hughes suffered from depression and was a professor of ocean sciences at the University of Alaska-Fairbanks. He was unmarried and had no children, and is survived by a sister. Six years after Plath’s death, Ted Hughes’s next lover also committed suicide.
