Lord Theodore Harper, Planetary Grand Duke of Manticore, was a Manticoran citizen and one of the highest-ranking peers of the realm.[1]

Harper was a nephew of Hamish Alexander, Earl White Haven and his wife. He was one of the very few Manticoran nobles to outrank Honor Harrington after she had become Duchess Harrington. (HH10)


  1. According to Harrington, only 3 Manticoran peerages outranked her; the Grand Duchy of Manticore, Grand Duchy of Gryphon, and Grand Duchy of Sphinx.
