Weihenmayer was born September 23, 1968, in Princeton, New Jersey. At 15 months old, he was diagnosed with juvenile retinoschisis, with blindness the expected outcome by age 13. At age 4, Weihenmayer and his family moved to Coral Gables, Florida, and, in 1975, to Hong Kong, where Erik attended the Hong Kong International School for grades 2-6. As he was going blind, Weihenmayer fought against using canes and learning Braille. He wanted to hang on to his life in the sighted world. Upon returning to America, Weihenmayer and his family settled in Connecticut, where he attended Weston High School. He eventually turned to wrestling and became a prominent force in high school, captaining his team and representing Connecticut in the National Junior Freestyle Wrestling Championship in Iowa.
