The answer is involved. The origin was probably a clip used on clothing and didn't look like the paperclips we use today. The device we know today as a paperclip was first produced by the Gem company and some still call them Gem clips.
From Wikipedia:
The first patent for the paper clip was awarded to Samuel B. Fay of the United States in 1867.[1] It was designed to fasten labels to garments and textiles, but was also marketed as a paper clip. In 1877 Erlman J. Wright patented the first device explicitly designed as a paper clip, resembling present models. Several new U.S. patents followed during the last decades of the 19th century. The most common type of wire paper clip still in use was never patented, but it was most likely in production in Britain as early as 1890 by "The Gem Manufacturing Company".
