VERNON K. KRIEBLE, who taught chemistry for more than 50 years at Trinity College in Connecticut, founded American Sealants. The company, which was responsible for the invention of Super Glue, was later named Loctite. In 1953, Mr. Krieble created an innovative anaerobic sealant–a liquid bonding resin that hardened in the absence of air–based on a conversation with his son, Robert, who also was a chemist. The new sealant provided a solution to the age-old problem of loose nuts and bolts in machines and appliances.
