Alfred Mosher Butts, American game designer, invented Scrabble (born 1899)

Alfred Mosher Butts was an American architect, famous for inventing the board game Scrabble in 1938.

Scrabble is a word game in which two to four players score points by placing tiles, each bearing a single letter, onto a game board divided into a 15×15 grid of squares. The tiles must form words that, in crossword fashion, read left to right in rows or downward in columns and are included in a standard dictionary or lexicon.
