Harry Welsey Coover Jr., the inventor of Super Glue, died at home in Kingsport, Tenn. Sunday, the Associated Press reports. He was 94 years old.
He invented Super Glue in 1942, as a result of a laboratory accident. Coover was experimenting with making different clear plastics for gun sights at Tennessee Eastman Company, and discovered that cyanoacrolates adhered things together very effectively. Super Glue was introduced for retail sale in 1958.
President Barack Obama awarded Coover the National Medal of Technology and Innovation in 2010, and Coover was inducted into the National Inventors Hall of Fame in 2004.
