When I first started my Houdini chronology project, my initial task was to just confirm and catalog the already voluminous available information about the theaters and cites where Houdini played. But I've now reached a point where I have it so complete that any new discovery is a joy, especially when it's a city that I have no record of him playing.
One such discovery is below. Houdini played a Junior Orpheum Theater in Urbana, Illinois, as half of a split week on September 27, 28, 29, 1923.
So congratulations Urbana! You are now on the list of cities that enjoyed Harry Houdini.
