This bottle of glue was featured in a “Northwest Inventions” exhibit at MOHAI in 1992. Some of the information from that exhibit was drawn from "Sexless Oysters and Self-tipping Hats: 100 Years of Invention in the Pacific Northwest” by Adam Woog. From the book: “Elmer O. Pearson, a Swedish emigrant, settled in Seattle in 1907 and became a chemical engineer specializing in adhesives. In the 1930s, he was working for Borden Mill when he developed the formula for -- you guessed it -- Elmer's Glue. Pearson signed the rights away to Borden and never made any money from his invention." However, other sources contradict this claim. Borden was an Ohio-based company that primarily sold milk products and has a cow mascot named Elise. As Elsie grew in popularity, the brand introduced “husband” Elmer and several calves in advertisements. Borden also made glue with casein (a milk byproduct) and an improved formula produced in 1951 became “Elmer’s Glue-All.”
