Robert Wadlow, Tallest Man

Who is the tallest man in recorded history? You may know the answer if you live near Alton, IL, or have ever visited a Guinness World Records Museum or a Ripleys Believe It or Not Museum.

Robert Wadlow was born in Alton, IL, on February 22, 1918, to very average sized parents. His mother was about 5 ft 6 in tall, and his father was about 6 ft tall. When he was born, he weighed 8 lb 6 oz, and was about 18 inches long. Very normal. Unfortunately, this was the only time in his life that he was normal sized.

Robert suffered from a condition called hyperplasia of his pituitary gland. Hyperplasia is a condition where an organ produces an unusually high amount of cell. In Robert's case, the overabundance of cells in his pituitary gland caused him to continue to rapidly grow his whole life. His size caused him a great deal of pain, so he had to wear leg braces in order to walk. It got to the point he couldn't feel his feet or most of his legs. He would walk with a cane, but refused to use a wheelchair.

He became a celebrity starting in 1936 when he toured with the Ringling Brothers Circus. He continued to tour in the following years, but in those tours he wore his own street clothes. On June 27, 1940, he was measured and checked in at 8 ft 11.1 in tall, officially being declared the tallest person on record. On July 4, 1940, he was at a public appearance at the Manistee National Forest Festival. His leg brace irritated his ankle which caused a blister that soon became infected. Doctors performed a blood transfusion and a emergency surgery. His condition grew worse, and he died in his sleep on July 15, 1940. He was buried in a 10 foot long casket that weighed nearly half a ton.

Below is a list of events in his life and how tall he was at the time.

When he began to walk at 11 months old, he was about 3 ft 5.75 in tall and weighed 45 lbs.
At age 4 1/2, he passed his mother's height. He was 5 ft 6.5 in tall and weighed 120 lbs.
At age 5, he attended kindergarten. He was 5 ft 10 in tall and weighed 143 lbs.
At age 6, he passed his father's height. He was 6 ft tall and weighed 160 lbs.
At age 9, he was strong enough to carry his father upstairs. He was 6 ft 5 in tall and weighed 180 lbs.
At age 13, he wore a size 25 shoe size. He was 7 ft 4 in and weighed 301 lbs.
At age 18, he was 8 ft 4 in tall and weighed 391 lbs.
At age 22, he was 8 ft 11.1 in tall and weighed 492 lbs.

Although the condition of hyperplasia of the pituitary gland is rare, it does happen. Once the diagnosis has been made, it is possible to correct it. This treatment only stops growth, so if you are already abnormally large, you will stay that way, but you won't continue growing.
