Yes and there's all sorts of proof that Harry Houdini existed, strangely none of it proves the man performed miracles.
Ahhhh Harry Houdini. Father of Skepticism and Debunking religious hoaxers. Being from his hometown, I know a little bit about him.
Of course, why was he doing all this? Because he really wanted to know the truth of what existed after death. He wanted proof and strove to find it. During the hight of Spiritualism, he debunked dozens if not hundreds of frauds preying on the public gullibility.
BUT... in all that time he did not deny that there COULD NEVER be anything supernatural. He wanted there to be proof so he could worship it. He never found any that he was satisfied with. He was also unable to escape death to send back a message to his beloved.
Of course, his followers and adherents have turned many of his techniques to disprove frauds into reasons to claim to disprove the supernatural or anything they cannot repeat as balderdash
