David Singmaster, author of the first book on how to solve the Rubik Cube, had a vast collection of mathematical books, papers, ephemera, and a huge collection of twisty puzzles, and other puzzles. His wish was that it remain in the UK, and he really, really wanted it to stay as a collection. But it's effectively impossible. Collections, even significant collections[0], are hard to keep together. I wish I had the money necessary to acquire and make accessible collections like this. [0] I'm not saying David's collection is significant, but it is substantial, and contains many things potentially of interest.
