Dash Hardeen was the brother of Harry Houdini and founder of the Magicians Guild of America.
In the Timeless Universe
When Garcia Flynn goes back to 1893 during the World's Columbian Exposition, with Lucy Preston, to kill Thomas Edison, Henry Ford, and J. P. Morgan, Lucy suggests using the help of Harry Houdini to pick the locks necessary to get inside the building they are meeting in. Before they do this, Flynn, Lucy, and Karl go to watch a performance by Houdini. Dash Hardeen acts as a stage assistant at this performance.
- The credits of the episode "The World's Columbian Exposition" inaccurately state this historical figure's name was "Dash Houdini."
