Patent Drawing for Joseph F. Glidden's Improvement to Barbed Wire, 11/24/1874. While the later half of the 19th century saw a series of patents for barbed wire, it was this one that has proven to be the most enduring. In 1874 Joseph Glidden, an Illinois farmer, patented an improved design which held the wire barbs in place. Glidden's wire was the leading barbed wire used while the West was being settled; since that time, there has been little change to his innovation. From the National Archives.

Public Domain: Glidden died in 1906.
