(ANSA) – Rome, May 14 – American chemist Spencer Silver, the inventor of the resin used in post-it notes, dies in his 80s. The international media reported this citing Family and 3M.
Born in San Antonio, Texas in 1941, Silver received a bachelor’s degree in chemistry from Arizona State University, a master’s degree in 1962, and a doctorate in organic chemistry from the University of Colorado at Boulder in 1966, before becoming chief chemist at Central Research Laboratories at 3M. In 1968 he developed a “low doc” adhesive that was strong enough to hold the sheets together, but weak enough to allow them to peel back without being torn. It can be reused many times. This resin was patented in 1972. Inventor and scientist Arthur Fry thus created bookmarks using Silver’s own resin. Sticky notes were initially sold under the name Post My Peel in four American cities from 1977, and then from 1980 across the United States as Post-It Notes. The product quickly became very popular and soon sold around the world.
He worked at Friday 3M until his retirement in 1996. He has been named in more than 30 patents. He has received numerous works, including the 1998 American Chemical Society Award for Creative Innovation and was inducted into the National Inventors Hall of Fame in 2011. (ANSA).
