Some inventions and their authors are wellknown around the world.
But there are noteless inventions which it would seem had always been.Crosswords are enjoyed by many kids and adults.
A crossword is considered as a word puzzle that normally takes the form of a square or a rectangular grid of white and black shaded squares.The goal is to fill in the white squares with letters, by solving clues which lead to the answers. The shaded squares are used to separate the words. It’s so usual! But mankind hasn’t known crosswords until 1913. While in Pittsburgh, Arthur Wynne played the violin in the Pittsburgh Symphony Orchestra. Later he moved to New Jersey where he worked as a freelancer for Cedar Grove. There he became known for the invention of the crossword puzzle in 1913. His puzzles were published in the newspaper and were very popular among readers. Then, in New York Wynne created the page of puzzles for the “Fun section” of the the New York World.
For the end of 1913 a puzzle with a diamond shape was introduced.
He called it a “WordCross Puzzle”. Wynne pioneered the use of blackandwhite grids to separate words in rows and columns.
Nowadays there are lots of crosswords’ variants, but the principles of Wynne’s WordCross puzzles are still used for modern crosswords.
