There have been a number of items that were called "paper clips," some as early as 1867 (Samuel Fay's design), but these items bore little similarity to what we know as a paper clip today. While many sources say that Norwegian Johan Vaaler invented the paper clip in either 1899 or 1901, this may be a myth. More recent information seems to prove that what Vaaler invented did not look at all like the item with which most of us are familiar. The man who invented the modern paper clip was probably William D. Middlebrook of Waterbury, Connecticut; he patented it in 1899, and then sold the patent to the Cushman & Denison Company in New York. They began marketing it under the name of Gem Paper Clips.This is no longer as clear-cut as it once was, as the actual inventor is in dispute, but the best date seems to be 1899.
