Ernst Schertel

Ernst Schertel (20 June 1884 – 30 January 1958) was a German author, probably best known for his 1923 ''Magic: History, Theory and Practice''. He had an "astonishingly diverse career", including running an eight-member dance troupe, the Traumbuhne Schertel, which was active from 1925 to 1927.

Schertel's ''Magic: History, Theory and Practice'' was found to be one of the most-heavily annotated books in Adolf Hitler's personal library. Provided by Wikipedia
