     Erik Weihenmayer was born with an eye disorder. As a child his eyesight became worse and then,

at the age of 13, he lost his sight completely. However, he did not lose his determination to lead a full

and active life.

     Erik became an adventurer. He took up parachuting, wrestling and scuba diving. He competed in

long-distance biking, marathons and skiing. His favorite sport, though, is mountaineering.

     As a young man, Erik started to climb mountains. He reached the summit of Mount McKinley in

1995 and then climbed the dangerous 1000-metre rock wall of EI Capitan. Two years later, while

climbing Mount Kilimanjaro in Kenya with his girlfriend, they stopped for a time at 13,000 feet above

sea level-in order to get married. In 1999, he climbed Aconcagua, the tallest mountain in South

America.And then, on May 25, 2001, at the age of 33, Erik successfully completed the greatest

mountaineering challenge of all. He climbed Mount Everest, the highest mountain in the world.

     Erik invented his own method for climbing mountains. He carries two long poles: one to lean on

and the other to test the way ahead of him. The climber in front of him wears a bell to gu ide him.

Erik is a good team member. He does his share of the job, such as setting up tents and building

snow walls.

      Although he could not enjoy the view, Erik felt the excitement of being on the summit of Everest.

He hopes that his success will change how people think about the blind."When people think about

a blind person or blindness, now they will think about a person standing on top of the world."
