# Ozanam, Jacques (1640–1717)

Jacques Ozanam was a French mathematician, scientist, and writer best remembered for his book
on mathematical and scientific puzzles *Récréations mathématiques et
physiques* (four volumes, 1694), which later went through ten editions.
Based on earlier works by Claude Bachet,
Claude Mydorge, Leurechon, and Schwenter,
it was later revised and enlarged by Jean Montucla,
then translated into English by Charles Hutton (1803, 1814). Edward Riddle
edited a new edition, which was published in 1844, removing some old material
and adding new material so that "[T]he work might continue to be to the
present generation a useful manual of scientific recreation, as its predecessors
have been to the generation which has passed. Ozanam's original edition
contained an early example of a problem about orthogonal Latin
squares: "Arrange the 16 court cards so that each row and each column
contains one of each suit and one of each value."
