Post-It Notes Inventor Spencer Silver Dies At Age 80
The man who invented the “sticky” part of Post-It Notes has died. Spencer Silver was 80 years old and was residing in St. Paul, Minnesota.
In 1968, Silver was working in a lab when he discovered an adhesive formula that allowed notes to be easily attached to surfaces, removed, and re-posted without leaving residue like other glues.
In 1974, a colleague then came up with the idea of using the adhesive to prevent bookmarks from falling out of his hymnal.
The product was originally called the Press ‘n’ Peel memo pad but didn’t really take off until 1980 when it was renamed the Post-It Note.
