The History of Pentominoes
Date: 10/22/95 at 0:20:10 From: Anonymous Subject: What is the history of pentaminoes? I have tried to find information on the web and gopher and I have used an archie search. I have also looked in magazine article searches. I would just like to know who "invented" or developed pentominoes and any background information. Thank you.

I don't know about any web resources concerning them, but look for books by Martin Gardner at your local library. I think there may be stuff in the Second Scientific American book of Mathematical Puzzles and Diversions, but you could check other of his books as well. If we come up with more, we'll let you know. Good luck! - Doctor Andrew, The Geometry Forum

Here is something I found at the MacTutor History of Mathematics Archive: The game of pentominoes is of more recent invention. The problem of tiling an 8 x 8 square with a square hole in the center was solved in 1935. This problem was shown by computer to have exactly 65 solutions in 1958. In 1953 more general polyominoes were introduced. It is still an unsolved problem how many distinct polyominoes of each order there are. There are 12 pentominoes, 35 hexominoes and 108 heptominoes (including one rather dubious one with a hole in the middle!). Puzzles with polyominoes were invented by Solomon W. Golomb, a mathematician and electrical engineer at Southern California University.
