David Tobias "Theodore" Bamberg (aka Fu Manchu) (19 February 1904 – 19 August 1974) was an itinerant magician who traveled with his full evening magic show from the early to mid part of the 20th century. In Bamberg's autobiography, Robert Parrish wrote in the introduction that no other great illusionist could match Bamberg's skill. The Fu Manchu show was known for its comedy, drama, and color.
Bamberg was the sixth and final member of the Bamberg Magical Dynasty, a Dutch family of conjurers whose magical lineage was passed from each of the first-born sons.
