Who Invented Stapler?

The stapler was invented by George W. McGill in the 1860s. He patented the first mechanical stapler in 1866, though earlier versions of devices for fastening papers together existed before his design. McGill's stapler used small metal pins, or staples, to bind papers, and his design eventually evolved into the staplers we use today.

Interestingly, earlier staplers were custom-made for specific royal or governmental use, such as one designed for King Louis XV of France, which was used to fasten documents with gold staples!
