Charles Hampson Grant. a native of New Jersey.
He was two years younger than George. Even before moving to Peru. Vermont, at the age of 10, young Grant had built a glider of his own design which flew 128 feet on the street in front of his house. After moving to Vermont, Grant constructed another glider in 1909. The aircraft crashed on its first flight and was never rebuilt. He made his first successful flight in a new. much better glider on August
15. 1910. He continued to build gliders for the next five years. A ruptured eardrum
prevented his learning to fly an aIrplane. Instead, he went on to study engineering
at Princeton University and later at Massachusetts Institute of Technology and
became a nationally recognized designer of aircraft. He influenced the lives of thousands of American youth in their pursuit of inventiveness and technical
achievement through model aircraft building and as editor of the foremost model
aircraft magazine of its day. As of 1985, Charles Hampson Grant is still living in
the Manchester, Vermont. area. He is 91 years old.
