Would appreciate any info on Franz "Frank" Kukol, Houdini's assistant from 1900 until at least 1924. The standard bios say he was Viennese, had a circus background, was a proficient musician, photographer and advance man. Would like more details and documentation on all this. Bios also say he left Houdini in 1914, but I have letter from Houdini stating Kukol was still working for him as late as 1924.
All facts and leads greatly appreciated.
