acrostic

Inspired by a game that his grandfather taught him they called magic squares, contributing correspondent to the New York World Arthur Wynne (Liverpudlian by birth, *1871 – †1945) published his first “word-cross” puzzle in the special Christmas Sunday supplemental of the paper on this day in 1913. With the letters F-U-N (the name of the jokes and tricks section of the paper) prefilled, the puzzle was a symmetrically arranged diamond and due to a subsequent typesetting switch a few weeks later, Wynne’s creation became known as the crossword ever since.
