Dancer Adrianne Haslet-Davis, left, performs on stage with dancer Christian Lightner at the 2014 TED Conference, in Vancouver, British Columbia.
She was a dancer who lost her left leg in the 2013 Boston Marathon bombing. She took to the stage with a new prosthetic limb to perform for the first time since losing part of her left leg. After 200 days of work, for the first time she danced a rumba on her new leg, to raucous applause from the crowd.
See her above, with dance partner Christian.
With her husband Adam Davis, an Air Force captain, they were both injured in the Marathon bombings.
