I tried this on "another" forum and got nowhere fast. As both an experienced builder and far less experienced performer who had good backstage help, I know that the "man behind the curtain" (not sexist, just Wizard of Ozish)is crucial to a career.
In Houdini's case, it was by and large Jim Collins for many years. However, info on Collins is sparse... to the point of non-existent in my searching. Lots of Houdini- little Collins.
Does anyone know where I might find more?
