James Edward Hanger
His Company was Hanger Inc.
His design had hinges at the kneee and foot.
On June 1, 1861, 18-year-old engineering student James Edward Hanger left his family, forgoing his studies at Washington College (now Washington & Lee University), to join his brothers in the Confederate Army. On June 3, less than two days after enlisting, a cannonball tore through his leg early in the Battle of Philippi. Becoming the first amputee of the Civil War, the young Hanger survived an excruciating battlefield amputation necessary to save his life by Dr. James D. Robinson.
Today Hanger Inc has annual sales over 1 billion dollars.
