Early life 
Arthur Wynne settled for a time in Pittsburgh, Pennsylvania, where he worked on the Pittsburgh Press newspaper and played the violin in the Pittsburgh Symphony Orchestra. He later moved to New York City and worked on the New York World newspaper. He is best known for the invention of the crossword puzzle in 1913, when he was a resident of Cedar Grove, New Jersey.
Wynne created the page of puzzles for the Fun section of the Sunday edition of the New York World. For the December 21, 1913 edition, he introduced a puzzle with a diamond shape and a hollow center, the letters F-U-N already being filled in. He called it a "Word-Cross Puzzle".
Although Wynne's invention was based on earlier puzzle forms, such as the word "diamond", he introduced a number of innovations (e.g. the use of horizontal and vertical lines to create boxes for solvers to enter letters). He subsequently pioneered the use of black squares in a symmetrical arrangement to separate words in rows and columns. With the exception of the numbering scheme, the form of Wynne's "Word-Cross" puzzles is that used for modern crosswords.
A few weeks after the first "Word-Cross" appeared, the name of the puzzle was changed to "Cross-Word" as a result of a typesetting error. Wynne's puzzles have been known as "crosswords" ever since.
