Sundback was born on April 24, 1880 in Småland, Sweden; after he had finished his studies he moved to Germany, and in 1905 he emigrated to the U.S.
Working as an engineer for the Universal Fastener Company in Hoboken New Jersey, Sundback perfected the old idea of a fastener based on interlocking teeth.
His "Hookless No. 2" invention -- basically the modern metal zipper -- was patented in 1917.
