The Post It Note may have been a God-sent, literally. In the early 1970s, Art Fry was in search of a bookmark for his church hymnal that would neither fall out nor damage the hymnal.

Fry noticed that a colleague at 3M, Doctor Spencer Silver, had developed an adhesive in 1968 that was strong enough to stick to surfaces, but left no residue after removal and could be repositioned. Arthur Fry took some of Spencer Silver's adhesive and applied it along the edge of a piece of paper. His church hymnal problem was solved!

Arthur Fry soon realized that his "bookmark" had other potential functions when he used it to leave a note on a work file, and co-workers kept dropping by, seeking "bookmarks" for their offices.
