Whitcomb L. Judson
From Wikipedia, the free encyclopedia
Whitcomb L. Judson (1836-1909) was an American inventor, born in Chicago, Illinois. Whitcomb is most famous for inventing the forerunner of the modern zipper in 1893, which he called the clasp-locker. During his lifetime, he obtained patents for the zipper, motor improvements and railroad brakes improvements. He also made a number of automobile improvements, one of which made his son a millionaire. This invention is what we now know as the cupholder.
Judson has had a high school in Converse, Texas named in his honor.
