Harry T. Hayward (c. 1865 – December 11, 1895) was an American socialite, gambler, arsonist, and murderer, dubbed by newspapers of the era as the "Minneapolis Svengali" for his ability to manipulate others. A seemingly respectable member of polite society, Hayward masterminded one of America's most infamous crimes during the Gilded Age—the 1894 murder for hire of dressmaker Catherine Ging.
