While looking on the web I saw this hilarious cat door stop. I thought it was really clever idea and I started to wonder about who invented the door stop. Although humans have been using door stop since the creation of the door, it wasn't until Dec 10, 1878 that anyone received a patent for it. Whom you may ask received the patent? It was a man by the name of O.Dorsey. This African American inventor not only developed the doorstop but he also invented the doorknob.
