World Tallest Person

Robert Pershing Wadlow  was born on February 22, 1918 in Alton, Illinois, also known as the Alton Giant and the Giant of Illinois. He was an American who became famous as the tallest person ever in world recorded history.

Robert Pershing Wadlow Was 8 ft 11.1 in (2.72 m) in height and weighed 439 lb (199 kg) at his death at age 22. His great size and his continued growth in adulthood were by the reason of  hyperplasia of his pituitary gland, which results in an abnormally high level of human growth hormone. He showed no indication of an end to his growth even at the time of his death.

Wadlow was the oldest of five children. He was taller than his father by the age of 8, and in elementary school they had to make a special desk for him due to his size. By the time he had graduated from Alton High School in 1936, he was 8 ft 4 in (2.54 m). After graduating he enrolled in Shurtleff College with the intention of studying law. 

Robert’s peak daily food consumption was 8000 calories – more than three times the amount recommended for average-sized males.


For his giant growth, he required leg braces to walk and had little feeling in his legs and feet. Despite these difficulties, he never used a wheelchair.

Wadlow became a celebrity after his 1936 U.S. and made a tour with the Ringling Brothers Circus. In 1938, he did a promotional tour with the International Shoe Company (since 1966 called INTERCO). They provided him his shoes free of charge. Examples still exist in several locations throughout the U.S., including Snyder’s Shoe Store of Ludington and Manistee, Michigan, and the Alton Museum of History and Art. He continued participating in tours and public appearances, though only in his normal street clothes. He possessed great physical strength until the last year of his life, when his strength and his health in general began to deteriorate rapidly.


Wadlow was a member of the Order of DeMolay, the Masonic-sponsored organization for young men. In 1939, he petitioned Franklin Lodge #25 in Alton, Illinois, and by late November of that year was raised to the degree of Master Mason under the jurisdiction of the Grand Lodge of Illinois A.F and A.M.. His Freemason ring was the largest ever made.

End of His Life

On the date of  July 4, 1940, during a professional appearance at the Manistee National Forest Festival, a faulty brace irritated his ankle, causing a blister and subsequent infection. Doctors treated him with a blood transfusion and emergency surgery, but his condition becoming very vad due to an autoimmune disorder, and on July 15, 1940, 11 days after contracting the infection, he died in his sleep at the age of 22.

 His coffin measured 10 feet 9 inches (3.28 m) long by 32 inches (81 cm) wide by 30 inches (76 cm) deep, weighed 1,000 pounds (450 kg) and was carried by twelve pallbearers and eight assistants. He was buried at the Oakwood Cemetery in Upper Alton, Madison County, Illinois.

His last words were ‘The doctor says I won’t get home for the….celebrations’.
