Artur Fischer, Inventor With More Patents Than Edison, Dies at 96 - The New York Times

One of Mr. Fischer’s most recent inventions is a gadget that makes it possible to hold and cut the top off an egg of any size. He got started on the problem when a hotel owner complained to him that his guests, on opening their boiled eggs for breakfast, always made a mess — the year was 1946.
