An accidental discovery made by Dale Kleist was the crucial breakthrough
needed for manufacturing insulation-quality glass
Born in Newark, Ohio, Kleist studied at Ohio State University before working as a researcher at Owens-Illinois Glass Company in 1932. Teaming with Games Slayter and Jack Thomas to create better glass technology, Kleist attempted to seal together architectural blocks by melting and spraying glass over them. Although Kleist was unsuccessful sealing the blocks, the errant spray of molten glass inadvertently formed tiny glass fibers.
