Harry August Jansen (October 3, 1883 – June 15, 1955) was a Danish-born entertainer who settled in the United States. He traveled the world as a professional magician under the name Dante the Magician.
He was born on October 3, 1883 in Copenhagen, Denmark.
Jansen came to St. Paul, Minnesota at the age of six with his family. The family's surname was Jensen
At the age of 16 Jansen made his stage debut under Charles Wagner. He then set off on a world tour for 5 years as The Great Jansen. In 1922, magician Howard Thurston, realizing Jansen's talent and possible competition to him, engaged Jansen to star in the #2 Thurston show. Thurston gave Jansen the stage name of Dante. The name came from the original Dante, Oscar Eliason (1869–1899), who had been killed in a tragic hunting accident in Australia years earlier. In 1925, Dante the Magician Inc. came into being with Thurston as co-owner. The 2nd unit Thurston show was built and co-produced by Jansen.
