In the complete medical and anthropological record of the human species, one name stands unchallenged at the absolute summit of physical stature: Robert Pershing Wadlow. Born in the quiet river town of Alton, Illinois, in 1918, Wadlow grew to an officially verified clinical height of eight feet eleven point one inches (272 centimeters) before his untimely death at the age of twenty-two. Known affectionately across depression-era America as the “Gentle Giant” or the “Alton Giant,” Wadlow never stopped growing for a single month of his life, navigating an ordinary-sized world with unfailing courtesy, modesty, and quiet stoicism.
An 8.7-Pound Newborn WhoReached Six Feet in Kindergarten
When Robert Wadlow was born on February twenty-second, 1918, in Alton, Illinois, as the eldest of five children born to Harold and Addie Wadlow—both of whom were of completely normal height, as were all four of Robert’s younger brothers and sisters—he weighed a totally unremarkable 8.7 pounds. Within months of his first birthday, however, an overactive, hypertrophic pituitary gland began flooding his body with excessive levels of human growth hormone.
His childhood growth chart reads like an anatomical impossibility:
- Age 1: Stood 3 feet 3.5 inches and weighed 45 pounds.
- Age 5 (Entering Kindergarten): Stood 5 feet 4 inches—already taller than his teacher, wearing clothes made for a seventeen-year-old teenager.
- Age 8: Reached 6 feet 2 inches and 169 pounds, able to pick up his father Harold in his arms and carry him up the stairs of the family living room.
- Age 13: Became the world’s tallest Boy Scout at 7 feet 4 inches, requiring a custom-made canvas tent and consuming up to eight thousand calories a day.
- Age 18 (High School Graduation in 1936): Measured 8 feet 4 inches and 390 pounds, where his school had to bolt special blocks under his wooden desk so his knees could fit underneath.
Size 37AA Shoes and Goodwill Ambassador Across 41 States
In an era before modern endoscopic brain surgery or hormone-suppressing medications existed, doctors at Barnes Hospital in St. Louis examined Wadlow and concluded that attempting open brain surgery to destroy or shrink his pituitary gland was far too likely to kill him. Determined to live as normal a life as possible, Robert enrolled at Shurtleff College with the dream of studying law, though he had to drop out after one year because his immense height and lack of sensation in his lower legs made walking across icy campus steps with a cane too hazardous, and even holding a small fountain pen inside hands that measured 12.75 inches from wrist to middle fingertip was difficult.
In 1938, after briefly touring with the Ringling Bros. Circus—where he strictly refused to wear top hats or circus costumes, appearing only in a sharp, custom-tailored three-piece business suit at Madison Square Garden and Boston Garden—Wadlow accepted a respectable job as a roving goodwill ambassador for the International Shoe Company (Peters Shoe Company). In exchange for promotional appearances at local shoe stores across the country, the company provided Wadlow free of charge with his custom-crafted Size 37AA leather shoes (measuring 18.5 inches long, which normally cost one hundred dollars a pair during the Great Depression—equivalent to over two thousand dollars today). Accompanied by his devoted father Harold, who removed the front passenger seat of the family’s 1937 Ford sedan so Robert could sit in the back seat and stretch his four-foot-long legs all the way up to the dashboard, Wadlow traveled over three hundred thousand miles across forty-one states and eight hundred towns.
The Final Measurement of 8’11.1″ and the Fatal Blister of 1940
On June twenty-seventh, 1940, Drs. Charles Humberd and Cyril MacBryde of Washington University in St. Louis measured the twenty-two-year-old Wadlow one final time: he stood 8 feet 11.1 inches (2.72 meters) tall and weighed 439 pounds, still growing at a rate of more than an inch per year.
Because his circulatory and nervous systems had to stretch across nearly nine feet of bone and tissue, Wadlow suffered from severe peripheral neuropathy in his feet—meaning he could not feel pain, rubbing, or blisters below his ankles, and required steel leg braces strapped around his calves to keep his ankles straight. Seven days after his final measurement, on July fourth, 1940, while marching in the Manistee National Forest Festival parade in northern Michigan, a poorly fitted iron strap on his ankle brace rubbed a raw blister into his skin without him feeling it. Within days, a raging streptococcal infection and septicemia set in. Confined to a hotel bed in Manistee because no hospital bed could hold him, and despite emergency blood transfusions, Robert Wadlow passed away in his sleep at 1:30 AM on July fifteenth, 1940—having uttered his gentle final words hours earlier: “The doctor says I won’t get home for the celebrations” (referring to his grandparents’ golden wedding anniversary). Forty thousand mourners attended his funeral in Alton, Illinois, where twelve pallbearers and eight assistants carried his thousand-pound, ten-foot-long steel casket to Oakwood Cemetery.
