Harry Lewis Nelson (born January 8, 1932) is an American mathematician and computer programmer with degrees in mathematics from Harvard University and Kansas University. Most of his professional career was spent at Lawrence Livermore National Laboratory where he worked with some of the earliest supercomputers. He was particularly noted as one of the world's foremost experts in writing optimized assembly language routines for the Cray-1 and Cray X-MP computers.

He was a member of the team thatwon the World Computer Chess Championship in 1983 and 1986, and was a co-discoverer of the 27th Mersenne prime in 1979 (at the time, the largest know prime number).

Mathematics is recreation to Harry. In fact, he served as editor of the Journal of Recreational Mathematics for five years and as Emeritus Editor, for subsequent years.

Harry has had a lifelong interest in puzzles of all types, and since his retirement in 1991 he has devoted his time to his own MiniMax Game Company, a "think tank" for games and puzzles. There are currently 20 mechanical puzzles and/or games on the U.S. market for which he has made substantial contributions, including RUSH HOUR(R) and Cool Circuits(TM).

3D PUZZLE DESIGNER: Hiroshi Yamamoto is an incredibly popular Japanese puzzle collector and designer of a large number of mechanical puzzles. He is the originator of many puzzle concepts including STORMY SEAS(R) and LUNAR LOCKOUT(R). Hiroshi tutors junior high school students who are preparing for the national entrance examinations for high school in Japan. He also writes for a mathematics magazine which is distributed locally. Presently, he is devoting himself to puzzles because he loves them. His goal is to"continue to design original things." Cool Circuits(TM) is one of his novel 3-dimensional puzzles and the first to be produced by ScienceWiz(R).


Hiroshi Yamamoto lives in Matto City in Japan, which is about 374 miles (601 km) northwest from Tokyo.
In personal communications to Harry Nelson, This may be the best puzzle you have ever designed. "Donald Ervin Knuth, an American computer scientist, mathematician, and professor emeritus at Stanford University. He is the 1974 recipient of the ACM Turing Award, informally considered the Nobel Prize of computer science.My eldest son received the Cool Circuits "game" when he was 7 years old and it was an immediate success. The circuits range in difficulty and are an interesting challenge for all abilities. My son is quite mathematically inclined and loves puzzles and now at age 10, he can still be found playing with the circuit game. His younger brother and sister, age 8 and 6 also enjoy having a go at working out a full circuit and of course, the "success" music makes it worthwhile for them. __ UK reviewer" It's an excellent way to support KS2 learning about circuits and the practical hands-on approach will ensure learning is memorable; it helps to develop spatial reasoning and abstract thinking. A super puzzle which children will keep returning to as they advance through the stages. " Parent's in Touch blog
