So you read the "Madman and the Professor" and thought it interesting. Edward Ruloff is another murdering philologist with the extra cachet that his 1871 trial for killing a dry-goods clerk was one of the first to test the admissability of photographs as evidence. The Supreme Court agreed with lower rulings that they could be allowed; Ruloff was hanged. In 1845, he had been accused of murdering his wife and child and was imprisoned for ten years for the abduction of his wife, but without a corpus delecti, he could not be convicted for the murder of his child. This man is writing a biography of Ruloff; a publisher could do a lot worse.
