The Artificial Leg is Invented
November 4, 1846
Benjamin Franklin Palmer of Meredith, New Hampshire, was not related to founder Benjamin Franklin, but the two shared a talent for invention. On November 4, 1846, Palmer received patent number 4,834 for the artificial leg. The artificial leg uses springs and metal tendons. The springs and tendons act like joints. They allow for bending and flexibility. Do you know what people used before artificial legs?
