Inventor of Mason Jar Died Poor, Alone and Forgotten
(p. 74) In 1859 an American named John Landis Mason solved the challenge that the Frenchman François (or Nicolas) Appert had not quite mastered the better part of a century before. Mason patented the threaded glass jar with a metal screw-on lid. This provided a perfect seal and made it possible to preserve all kinds of foods that would previously spoil. The Mason jar became a huge hit everywhere, though Mason himself scarcely benefited from it. He sold the rights in it for a modest sum, then turned his attention to other inventions - a folding life raft, a case for keeping cigars fresh, a selfdraining soap dish - that he assumed would make him rich, but his other inventions not only weren't successful, they weren't even very good. As one after another failed, Mason withdrew into a semidemented poverty. He died alone and forgotten in a New York City tenement house in 1902.
