Donn Charles Fendler (August 29, 1926 – October 10, 2016) was an American author and public speaker. Born in Rye, New York, Fendler, at the age of 12, became separated from his family and was lost on Maine's Mount Katahdin in July 1939. His disappearance launched a search party, which became headline news throughout the United States. Donn survived for nine days without food or proper clothing, before following a stream and telephone line out of the woods near Stacyville, Maine. Fendler was dehydrated, covered with insect bites, and 16 pounds lighter than at the beginning of his odyssey, but otherwise unharmed. He credited his experience as a Boy Scout in helping him survive the ordeal.
