The first is the discovery by William T. Tutte, A. H. Stone, R. L. Brooks, and
C. A. B. Smith of squares with integral sides that can be tiled by smaller squares with
integral sides, no two alike. Tutte tells the story in “Squaring the Square,” a beautifully
written article that conveys vividly the excitement of mathematical research [9]. It became
widely-read in 1958 when it was reprinted in Martin Gardner’s “Mathematical
Games” column in Scientific American. It undoubtedly played a role in inspiring many
to become mathematicians.
