Hugh Herr - American rock climber, engineer, and biophysicist.


Hugh Herr born October 25, 1964

The youngest of five siblings of a Mennonite family from Lancaster, Pennsylvania, Hugh Herr was a prodigy rock climber: by age eight, he had scaled the face of the 11,627-foot (3,544 m) Mount Temple in the Canadian Rockies, and by 17 he was acknowledged to be one of the best climbers in the United States.
In January 1982, after having ascended a difficult technical ice route in Huntington Ravine on Mount Washington in New Hampshire, Herr and a fellow climber Jeff Batzer were caught in a blizzard and became disoriented, ultimately descending into the Great Gulf where they passed three nights in −20 °F (−29 °C) degree temperatures. By the time they were rescued, the climbers had suffered severefrostbite. Both of Herr's legs had to be amputated below the knees; his companion lost his lower left leg, the toes on his right foot, and the fingers on his right hand. During the rescue attempt, volunteer Albert Dow was killed by an avalanche.
Following months of surgeries and rehabilitation, Herr was doing what doctors told him was unthinkable: climbing again. Using specialized prostheses that he designed, he created prosthetic feet with high toe stiffness that made it possible to stand on small rock edges the width of a coin, and titanium-spiked feet that assisted him in ascending steep ice walls. He used these prostheses to alter his height to avoid awkward body positions and to grab hand and foot holds previously out of reach. His height could range from five to eight feet. As a result of using the prostheses, Herr climbed at a more advanced level than he had before the accident, making him the first person with a major amputation to perform in a sport on par with elite-level, able-bodied persons.
Hugh Herr and author Patricia Ellis Herr are the parents of 
two daughters, Alexandra and Sage. Alex's earliest hiking achievements are described in Patricia's memoir, Up:
Mother and Daughter's Peakbagging Adventure
After his climbing career, Herr began to focus on academics, previously an area of little interest to him. He earned an undergraduate degree in physics at his local college, Millersville University, and a master's degree in mechanical engineering at MIT, followed by a PhD in biophysics from Harvard University.
While a postdoctoral fellow at MIT in biomedical devices, he began working on advanced leg prostheses and orthoses, devices that emulate the functionality of the human leg.

The computer-controlled knee, which is outfitted with a microprocessor that continually senses the joint's position and the loads applied to the limb, was named to the list of Top Ten Inventions in the health category by TIME magazine in 2004. The robotic ankle-foot prosthesis, which mimics the action of a biological leg and, for the first time, provides transtibial amputees with a natural gait, was named to the same TIME top-ten list in 2007.
Herr's story has been told by Alison Osius in the book Second Ascent: The Story of Hugh Herr; a Discovery Channel feature story; and in a 2002 National Geographic movie, Ascent: The Story of Hugh Herr.
Herr was featured on a March 25, 2012 episode of CNN's The Next List.
