On this day in 1846, Benjamin Franklin Palmer was granted the patent for ARTIFICIAL LEG. U.S. Patent No. 4,834.
The nature of this invention consists in new and improved articulations of the knee, ankles, and toes, in constructing the various parts in such new manner as to leave no opening in the exterior of the leg about the joints, and supporting and arranging tendons and springs in such a manner as to give more elasticity, strength, durability and freedom of motion to the limb than are to be found in artificial legs.
