Gideon Sundback emigrated to United States in 1905 and was hired to work for the Universal Fastener Company the next year. This was the start of his work with the zipper, Sundback made several advances in the development of the zipper between 1906 and 1914.
In 1914, Gideon developed a version of zipper based on interlocking teeth, the “Hookless No. 2”, which was the base of modern metal zipper. He later got a United States patent no. 1219881 for the “Separable Fastener”.
Sundback was not only involved in the invention of modern zipper but also created the manufacturing machine for the new zipper. He was awarded the Gold Medal of the Royal Swedish Academy of Engineering Sciences in 1951. Gideon died of a heart condition in 1954 and was honoured by inclusion in the National Inventors Hall of Fame for his work on the development of the zipper.
