John F. Carroll

John Francis Carroll was an American giant and one of 29 known people in medical history to have verifiably reached a height of 8 feet (240 cm) or more. He suffered from severe, 2-dimensional spinal curvature (kyphoscoliosis) and acromegalic gigantism. He had a standing height of 8 ft 1⁄4 in (244 cm) on October 14, 1959, at age 27, but according to calculations, his height would have been 8 ft 8 in (264 cm), assuming normal curvature of the spine. In 1968, he was later measured at 7 ft 10+1⁄2 in (240 cm), having shrunk in stature due to his worsening spinal condition.
