Robert Wadlow – The Tallest Man in Recorded History
Robert Pershing Wadlow, known as the Alton Giant and the Giant of Illinois, remains the tallest verified human being ever recorded. His height of 8 ft 11.1 in (2.72 m) continues to astonish, but his life was far more than a number on a measuring tape. Born in 1918 in Alton, Illinois, Wadlow lived a short but remarkable existence, shaped by a rare medical condition that drove his growth and ultimately contributed to his death at age 22.
His story is one of resilience, dignity, and a gentle nature that earned him the nickname “Gentle Giant.” While his height set records that still stand, his death from a simple infection—made fatal by a poorly fitted leg brace—remains a tragic reminder of the fragility of life. This article draws on verified records from Guinness World Records, Wikipedia, and historical archives to present the most accurate account of Robert Wadlow’s life and death.
How Tall Was Robert Wadlow? The Definitive Record
Robert Wadlow’s final height was measured at 8 ft 11.1 in (2.72 m) just 18 days before his death on June 27, 1940. He surpassed John Rogan as the tallest person ever recorded one year earlier. At the time of his death, he was still growing, and no medical treatment was available to stop his condition.

What Was Robert Wadlow’s Cause of Death?
Wadlow died at 1:30 a.m. on July 15, 1940, in a hotel in Manistee, Michigan. The immediate cause was a septic blister on his right ankle, which developed after a poorly fitted leg brace rubbed the skin a week earlier. The wound became infected, and despite surgery and a blood transfusion, his condition worsened due to an autoimmune response. While his immune system was poor, the infection itself was the direct cause of death.
What medical condition caused Robert Wadlow’s gigantism?
Wadlow’s extraordinary size and continued growth in adulthood were caused by hypertrophy (or hyperplasia) of his pituitary gland, which produced an abnormally high level of human growth hormone (HGH). This condition is medically known as gigantism. He was born to regular-sized parents and weighed an average 8.7 lb (3.85 kg) at birth, but his rapid growth began immediately. By age 5, he was already 5 ft 4 in (1.63 m) tall, and by age 17, he had surpassed 8 ft 4 in (2.54 m).
How did an infection lead to his death?
The leg brace that caused the blister was intended to support his frame, but the friction created an open wound. In an era before broad-spectrum antibiotics, such an infection could quickly become life-threatening. The septic shock that followed overwhelmed his body, and despite the best available medical efforts, he passed away at age 22.
No medical treatment was given to stop Wadlow’s growth because effective therapies for pituitary gigantism did not exist in the 1930s. Modern options like surgery or growth hormone inhibitors could have altered his outcome.
How Much Did Robert Wadlow Weigh and What Was His Shoe Size?
At his death, Wadlow weighed 439 lb (199 kg). His feet were the largest ever recorded, measuring 47 cm (18.5 in) in length, equivalent to a US size 37AA (UK 36, European 75). His custom shoes cost up to $100 at the time (roughly $1,500 today).
What was Robert Wadlow’s shoe size?
US size 37AA is the most widely cited measurement. Some older sources debate the exact size due to changes in sizing standards, but most agree on this figure. His feet were both long and narrow, requiring custom-made shoes from the International Shoe Company, which provided them free of charge during his promotional tours.
How did his weight fluctuate over time?
Wadlow’s weight increased steadily with his height. At age 5, when he was 5 ft 4 in, he weighed approximately 100 lb. By age 17, he had reached 8 ft 4 in and weighed around 350 lb. His final recorded weight of 439 lb was taken shortly before his death. There is no evidence of significant weight loss or gain outside the normal progression of his growth.
Wadlow’s feet remain the largest ever recorded in human history. The Guinness World Records entry for “largest feet” still lists his US 37AA size as the benchmark.
Did Robert Wadlow Have a Wife or Family?
Robert Wadlow did not marry and had no children. He was the oldest of five children, with two brothers (both of average height) and two sisters. His parents, Harold Franklin Wadlow and Addie May Johnson, were of average stature. He surpassed his father’s height by age 8 and was taller than adults by age 5. In school, a special desk was made for him due to his size.
What was Robert Wadlow’s personal life like?
Despite his unusual size, Wadlow was known for his kind, humble, and gentle nature. He was often called the “Gentle Giant.” He never used a wheelchair and possessed great physical strength until the last days of his life. In 1938, he began a promotional tour with the International Shoe Company, which provided him with free shoes. He viewed his work as advertising, not as a “freak show.”
Where Is Robert Wadlow’s Skeleton and What Happened After His Death?
After his death, Wadlow’s body was embalmed and his skeleton was prepared for medical research. It is held in trust by the Alton Historical Society and is not on public display. His family’s decision to preserve the skeleton reflects the early 20th century view of “medical curiosities” and its ethical evolution.
Why was his skeleton preserved?
The preservation was intended for scientific study of gigantism and human growth. Wadlow’s skeleton provides valuable data on bone structure and the effects of excessive growth hormone. Today, the remains are kept in a controlled environment, with access limited to researchers.
Is Robert Wadlow still the tallest man in recorded history?
Yes, Robert Wadlow remains the tallest verified person in recorded history. No other individual has been measured with the same level of certainty. The current tallest living person, Sultan Kösen of Turkey, stands at 8 ft 2.8 in, which is nearly 9 inches shorter than Wadlow.
If Wadlow were alive today, his height would still exceed the tallest living person by a significant margin. Modern treatments for gigantism—such as pituitary surgery or somatostatin analogs—could have potentially slowed his growth and prolonged his life.

Certainty vs. Uncertainty: What We Know and What Remains Unclear
Established Information
- Robert Wadlow is the tallest human for whom there is irrefutable evidence (Guinness World Records).
- He died from complications of a foot infection, specifically septic shock.
- His height was caused by a benign tumor on his pituitary gland (hyperplasia).
Information That Remains Unclear
- Whether he would have exceeded 9 feet if he had lived longer.
- Exact number of public appearances or specific details of his daily life are based on limited surviving records.

Background and Historical Context: Why Robert Wadlow Matters
Robert Wadlow’s case remains medically significant for understanding gigantism and acromegaly. The infection that killed him was exacerbated by a leg brace that rubbed a blister—a situation that might be easily treatable with modern antibiotics. Compared to other historical giants (e.g., John Rogan, Sultan Kösen), Wadlow’s proportions were symmetrical, which is rare. His family’s decision to preserve his skeleton reflects the early 20th century view of “medical curiosities” and its ethical evolution.
Wadlow’s story continues to captivate people worldwide, serving as a symbol of resilience and the extraordinary capabilities of the human body. His records are verified by Guinness World Records and his biography is extensively documented by the Alton Historical Society and other authoritative sources.
