Evolution of Paper Clips

An American patent for a bent-wire “paper clip or holder” was issued in 1898 to Matthew Schooley, thus predating the commonly cited “invention” of the paper clip in 1899 by the Norwegian Johan Vaaler. Just as Schooley’s patent drawings show different embodiments of the clip, so there are believed to have existed many other (unpatented) variations, some dating from as early as the 1870s.
