Wearing special legs he made for himself during his recovery and rehabilitation, Herr was soon out climbing again. With work, he was able to scale rock surfaces more difficult than those he’d tackled before the accident – not, he will tell you, because of the prostheses, but because he’d devoted himself to the sport. When he tired of the extreme-athlete life, Herr returned to school, enrolling at Millersville University in Pennsylvania. There, he discovered a passion for math and science and secured his first patent for prosthetic-limb design before graduating.
