Robert Wadlow – World’s Tallest Man

Robert Pershing Wadlow, remembered throughout the world as the tallest person in recorded medical history, was born on February 22, 1918, in Alton, Illinois. His middle name honored General John J. Pershing, reflecting the patriotic spirit common during the era. He was the first child of Harold Franklin Wadlow and Addie Johnson Wadlow and eventually became the eldest of five children. Robert was of average size at birth, weighing about 8.7 pounds, and there was nothing to suggest that he would become a medical phenomenon.

However, by the time he was only a few months old, his parents noticed that he was growing at an unusually rapid rate. Physicians eventually determined that his extraordinary growth was caused by hyperplasia of his pituitary gland, which produced an abnormally high level of human growth hormone. Unlike many forms of gigantism, his condition continued throughout his life because no effective treatment existed during that period. Wadlow spent his childhood in Alton, where he attended local public schools despite the considerable challenges created by his remarkable height.

His family and the community worked together to adapt everyday items to accommodate him, including specially built school desks and clothing. Although he attracted attention wherever he went, those who knew him consistently described him as gentle, polite, intelligent, and remarkably humble. He was active in the Boy Scouts, achieving the rank of Eagle Scout, and a custom-made Scout uniform, tent, sleeping bag, and other equipment had to be created to fit him. He graduated from Alton High School in 1936 and enrolled at Shurtleff College in Alton, where he studied law.

Although he never completed his degree, he enjoyed his college experience and remained interested in pursuing a legal career. As his fame spread across the United States, Wadlow became known as the “Alton Giant” and later as the “Gentle Giant.” During the late 1930s, he accepted a promotional position with the International Shoe Company, which provided him with specially made shoes in exchange for appearances

at stores and events across the country. Accompanied by his father, who drove a specially modified automobile with an extended driver’s area, Wadlow visited hundreds of cities and met thousands of admirers. These appearances transformed him into an international celebrity while also helping the public better understand his condition. He was often photographed standing beside average-sized adults or familiar objects to illustrate his extraordinary stature. Throughout his travels, he remained patient with reporters, photographers,

and curious spectators, earning widespread admiration not only for his height but also for his gracious personality. Robert Wadlow’s growth never stopped. At the time of his death, he stood 8 feet 11.1 inches (272 centimeters) tall and weighed approximately 439 pounds (199 kilograms). Because of the immense strain his size placed on his body, he required leg braces to support his weakened legs and feet. Ironically, despite his tremendous height, he had limited sensation in his

lower extremities due to nerve complications. This reduced sensitivity became a significant factor in his final illness. His clothing, furniture, bed, and many everyday items had to be custom built, and his shoes measured a size 37AA (U.S.), requiring the International Shoe Company to manufacture them specifically for him. Although Wadlow never married and had no children, he remained close to his parents and siblings throughout his life.

His calm demeanor, cheerful disposition, and willingness to engage with the public made him one of America’s most beloved celebrities during the late 1930s. Medical professionals frequently studied his condition, and his remarkable measurements were carefully documented. During his lifetime, he became recognized by medical authorities and the public as the tallest man ever reliably measured. Today, Guinness World Records continues to recognize him as

the tallest person in recorded history based on verified measurements. In July 1940, while making a public appearance at the Manistee National Forest Festival in Manistee, Michigan, a poorly fitted leg brace rubbed against his ankle and created a blister. Because he lacked normal sensation in the area, the injury went unnoticed until it became seriously infected. Despite emergency treatment that included surgery and blood transfusions, the infection spread. Robert Wadlow died in his sleep on Monday, July 15, 1940, at the age of 22. His death attracted national attention, and an estimated 30,000 to 40,000 people attended his funeral in Alton.

His casket measured over 10 feet long and weighed approximately 1,000 pounds with its contents, requiring numerous pallbearers and additional assistants to carry it. He was survived by his parents, Harold and Addie Wadlow, and his four younger siblings, Eugene, Betty, Harold Jr., and Helen. Robert Wadlow’s legacy continues to endure through numerous memorials, museum exhibits, photographs, and medical studies. A life-size bronze statue erected in his hometown of Alton remains a popular landmark,
