Innovation often involveds putting two and two together and making four. A simple idea from one plice combined with a simple idea from another place can yield gold. That's the story of Art Fry and the Post-It.

The Post-It was invinted when Fry's colleague, Dr. Spencer Silver in 3M's Central Research Department, came up with a weak adhesive that stuck strongly enough to keep pieces of paper together than could be separated without leaving a mark. It was an invention in search of a use.
The rest, as they say, is history.
