Adelaide Herrmann (1853–1932) was a well-known American magician and vaudeville performer billed as "the Queen of Magic." She was married to Alexander Herrmann The Great, another magician.
Herrmann herself came to New York City as a dancer for Imre Kiralfy. She began her magic career as assistant to her husband, magician Alexander Herrmann. They married in 1875 at City Hall, where New York City Mayor William H. Wickham performed their ceremony. Together, Alexander ("Professor Herrmann" or "Herrmann the Great") and Adelaide entertained audiences with a variety of magic tricks, including escape tricks and the bullet catch trick. In 1888, the Herrmanns put on a show wherein they revealed how the spiritualist Ann O'Delia Diss Debar was a fraudulent medium in front of journalists.
