American puzzle designer From Wikipedia, the free encyclopedia
Larry D. Nichols, born 1939 in the United States, is a puzzle designer. He grew up in Xenia, Ohio, and studied chemistry at DePauw University in Greencastle, Indiana, before moving to Massachusetts to attend Harvard Graduate School. He is best known for the invention of mechanical puzzles including 'The Nichols Cube Puzzle' (1972), patent US3655201.[1] He has lived with his wife Karen in Arlington, Massachusetts since 1959.

In 1957, 17 years before Dr. Rubik’s invention popularly known as the “Rubik's Cube”, Dr. Nichols conceived of a twist cube puzzle with six colored faces. It was a 2×2×2 cube assembled from eight unit cubes with magnets on their inside faces, allowing the cubes to rotate in groups of four around three axes. The object of the puzzle was to mix the colors on the faces of the cube and then restore them.
After making many preliminary models, in 1968 a working prototype was constructed, and on April 11, 1972, U.S. patent 3,655,201 was issued covering the Nichols' Cube. The patent focused on the 2×2×2 puzzle but mentioned the possibility of larger versions.
Nichols' patents became the subject of a court hearing, between his employer, and the Ideal Toy Company.[2][3][4] In 1985, a U.S. District Court ruled that Rubik’s Cube infringed the Nichols patent, but in 1986 the Court of Appeals ruled that only the smaller 2×2×2 Rubik’s Pocket Cube was guilty of infringement, and not the popular 3×3×3 Rubik's Cube.[5]
Nichols received a degree in chemistry in 1958 from DePauw University, where he was a Rector Scholar, and went on to earn a doctorate at Harvard. As a Harvard student, he invented and produced games and puzzles. He became chief scientist for the Moleculon Research Corporation of Cambridge, Massachusetts, and invented one of its primary products, Poroplastic, in 1973. Poroplastic film has the mechanical properties of a typical plastic, but is able to hold large quantities of almost any liquid within tiny pores. Usage of Poroplastic materials centers on controlled drug delivery and environmental health and safety products.[10]
