Greville died at Mayfair, London, and the celebrity now attached to his name is entirely due to the posthumous publication of a portion of a Journal or Diary that it was his practice to keep during the greater part of his life. These papers were given by him to his friend Henry Reeve a short time before his death, with an injunction that they should be published, as far as was feasible, at not too remote a period after the writer's death.
