Donald A. Koehler (September 1, 1925 – February 26, 1981) is one of 24 known people in medical history to have verifiably reached a height of 8 feet (240 cm) or more.
The Guinness Book of World Records confirmed Koehler at a standing height of 8 ft 2 in (249 cm) at his peak.
Koehler wore shoes that were size 22, but he once stated that his most bothersome clothing problem was finding socks that fit him.
Koehler died in 1981 in Chicago from a reported heart condition, by which time he was estimated to be about 7 ft 10 in (239 cm) tall.
[4][5][6] Per Koehler's wishes, his body was cremated, and his ashes scattered on Long Lake in Wisconsin where he liked to fish.
