Overview

Robert Pershing Wadlow (February 22, 1918 – July 15, 1940) is recognized as the tallest person in recorded history. His extraordinary stature made him a well-known public figure in the United States and a frequent subject of medical discussion about excessive growth caused by pituitary dysfunction. Despite physical challenges, contemporaries described him as courteous and dignified.

Early life and growth

Wadlow was born and raised in Alton, Illinois. He was of typical size at birth but grew rapidly from early childhood. His height continued to increase throughout adolescence and into young adulthood, a pattern consistent with excessive production of growth hormone before the end of normal bone development. By the time of his death at age 22 he had reached a recorded height of 8 ft 11.1 in (2.72 m).

Medical cause and health

Doctors attributed his unusual stature to a disorder of the pituitary gland that produced abnormally high levels of growth hormone, often referred to as pituitary gigantism. The condition affected his musculoskeletal and circulatory systems: he required leg braces for stability, had limited sensation in parts of his legs, and experienced progressive strain on joints and organs. Infections and circulation problems were among the medical risks linked to his size; a leg infection related to a poorly fitting brace contributed to complications that led to his death.

Public life and legacy

Wadlow made many public appearances, including promotional events and exhibitions, where he usually dressed in tailored clothing and custom-made shoes. He became popularly known as the "Gentle Giant" because of his polite and mild-mannered behavior. After his death he remained a figure of medical interest and popular fascination: his story is cited in discussions of gigantism, adaptive clothing and footwear, and the social experience of people with extraordinary physical traits.
