His growth spurt started in infancy, and he kept growing throughout his entire life thanks to a hyperactive pituitary gland problem. The condition caused his system to produce an abnormal amount of human growth hormone. Robert would continue to grow until the end of his short life.
In high school Robert was popular and active in many extracurricular activities, even serving as the advertising manager for the yearbook. He was completely accepted by his peers. However, when he attended college he lost that acceptance and struggled with the stares. It bothered him so much that he dropped out and returned to his parents quite penniless.
Robert was so popular that following his time with Ringling Bros. he signed a fabulous contract with The International Shoe Company. The deal included quite a bit of travel and personal appearances and in just under a year Robert had made over 800 appearances and traveled over 300,000 miles.
Robert broke the world record as the tallest man in history when he was 19, but he didn’t stop growing. He measured in at eight-feet, four-inches tall at that time.
Eventually his hands would grow to be too large for him to participate in his favorite hobbies, but this wasn’t the only downside to his larger frame. The physical toll on his health would ultimately bring his life to an abrupt and premature end.
He suffered from weak legs, and commonly experienced loss-of-feeling and numbness in his limbs and extremities. He depended on specially designed leg braces and a cane in order to move around—although he never used a wheelchair.
It was during an infection from a blister caused by one of these ill-fitted leg braces that Robert’s health took a serious turn for the worst. He underwent blood transfusions and emergency surgery in an attempt to save him, but ultimately the efforts of doctors were futile. His condition continued to decline because of an autoimmune disorder, and he succumbed to the infection. He died in his sleep on July 15 1940 - he was only 22 years old. When he passed away, he measured 8 feet 11.1 inches and weighed an astounding 439 pounds.
Robert Wadlow's body was viewed by 33,295 within 28 hours after his death. His funeral was attended by 40,000 mourners. It took twelve pallbearers to hoist his thousand pound casket. Robert was buried in Oakwood cemetery in Alton, Illinois on July 19, 1940 and required two normal size grave plots.
