Senefelder, Alois, << ZAY nuh `fehl` duhr, AH loys >> (1771-1834), invented a widely used printing process called lithography (see Lithography ). As a young man, Senefelder wrote plays. Because he could not get them published, he tried to print them himself. In 1798, while preparing to etch a limestone slab, he wrote on the slab with a wax crayon and found that the marks could be inked and printed. He called his invention chemischer Druck (chemical printing). Senefelder was born on Nov. 6, 1771, in Prague in what was then Bohemia (now the Czech Republic). He was educated in Munich, Germany. He died in Munich on Feb. 26, 1834.
