There’s some debate how the "Houdini hole"[1] in the ceiling got there: “The story that Charlie Root told me is a little different than what they say now. There is a national organization of magicians who are sure it was Harry Houdini who cut the hole in order to insert some sort of apparatus to levitate a woman. But, Charlie, who in 1971 was one of the only living people who had been in the theater during its glory days, told me it was Harry Blackstone, a magician who was nowhere near as famous as Houdini. That’s all I know. I have no idea if someone has been up there to see if there was something up there.”[2]
