Born on this day (April 24) in 1880, Sundback was the Swedish-American electrical engineer best known for his work developing the zipper.
He moved to the US in 1905 and joined the Universal Fastener Company in New Jersey the following year, before being promoted to head designer.
Building on the work of other engineers, Sundback made several improvements to the zipper between 1906 and 1914.
This work culminated in his invention of the Hookless Fastener No.1 and its follow-ups.
Sundback gained a patent for the Separable Fastener in 1917.
He died in 1954 at the age of 74, and was added to the National Inventors Hall of Fame in 2006 for his work on the zipper.
