Barbed Wire

Joseph Glidden

Barbed Wire Invention

Joseph Glidden was a small farmer who saw that people in the great plains were at a lack of wood for fencing. He saw that they would use bushes with sharp thorns to keep cattle in. One day at the county fair he saw a demonstration that caught his eye. There was a farmer that attached spikes to the top of wooden posts. So he thought that metal bent into thin strings with sharp points every foot or so would give them their needs. Joseph got the patent in 1874. It used little wood and was cheap but it led to the demise of free grassing on public land as small farmers would fence their animals on that land.
