One of the areas Max had expertise in was intellectual property. If he said the film was public domain, bank on it.
In one of our many meals together, he told me when the Annemann material would be going PD, which would allow him to do the large Annemann book. He had it down to the day that it all went PD. Max knew his stuff.
Max was a nice man, was generous to me both in sharing his encyclopedic knowledge of mentalism, and in selling me the odd title that I was looking for. He was an expert in old paperback books and jazz, having large collections of both subjects.
Max was a character. Once, as we were talking about Fourth Dimensional Telepathy, he mentioned that the "best" method had been developed by him. I offered to buy it but he said it was sold out. I told him I'd take a Xerox copy and he replied that he "did not deal in Xerox copies." I asked how he produced the originals and he said, "By Xerox." He then laughed at the contradictory nature of his response and supplied me with the pertinent material, plus one or two other things.
Unfortunately, I could not understand what he wrote and asked him about it, saying that the directions weren't that clear. Max responded that my observation was accurate as he didn't want anyone else doing the trick. The next time we met for lunch he explained the details that were purposely muddled in his text. Apparently, I was the only person who ever called him on it and he responded by teaching me his method. As I said, a character.
Unfortunately, Max's life was anything but neat and orderly. When he died without a will the Public Administrator took over. She told me that it was clear to her that Max had been clinically depressed for many years before his death.
Partial evidence of this was that when he would come home after working as an attorney he would sort his mail, keeping letters from friends, but everything else got tossed on the growing pile beside his front door. When he died this pile was around four feet in height, something his case worker told me was clear indiciation of depression. She's seen it many times and said there were thousands of dollars of uncashed checks in the pile.
After his death I could not locate Max's daughter quickly as they were somewhat estranged, but I did make certain he had a Jewish funeral. There were two magicians in attendance at the funeral: John Cannon and me. I helped carry the casket down the steep hill to where he was buried.
Later, his daughter who is more observant than Max was, thanked me for seeing that her father had a religious funeral. That was a comfort to her even though they hadn't been in contact for some time.
Some woman came out of the woodwork claiming to be Max's "widow," something she did not claim at the funeral or to the mortuary. To my knowledge, none of his friends knew about her and there didn't seem to be any evidence that she lived in Max's apartment with him, given that his book collection was everywhere in the place, including piles of books in the bathroom and shower.
The appearance and claim of a "widow" jammed up the disposition of his estate which was put into storage by the Public Administrator. I believe the daughter sold a car or two of Max's to pay for storage. I believe it is still sitting in storage and may for some time. The case worker retired and I have not bothered to check on the current status of the case or if the "wife's" claims have been resolved.
I do not know if Max sold some or all of his Annemann material prior to his death. If he did not disposed of this material, it remains in storage, under the care of the Public Administrator.
Final disposition of his estate may drag on for years.
