The fourth person ever to reach both Poles, Will Steger is known by many titles—educator, activist, photographer, and explorer. This former Explorer-in-Residence for National Geographic is a pioneer in his field, with a series of firsts in polar exploration to his credit. In 1986 he made the first confirmed unsupported journey to the North Pole, leading a team of eight people with 50 sled dogs. Two years later, he guided the longest unsupported dogsled expedition in history, a 1,600-mile south-north traverse of Greenland. In 1995, Will led a 1,200-mile expedition between Russia and Ellesmere Island, Canada, via dogsleds and canoe sleds with a team of five educators and scientists. This sweeping project earned him the prestigious National Geographic John Oliver La Gorce Medal. Will joined Roald Amundsen, Amelia Earhart, Admiral Robert Peary, and Jacques-Yves Cousteau in this honor. In 2004, he led a five-month journey through the Northwest Territories in Canada. Having testified before the U.S. Congress on polar and environmental issues, he has become a recognized authority on polar environmental concerns.
