American Robert Wadlow was known as the tallest man in the world, and he remains the tallest man ever recorded using reliable information. Wadlow was born on February 22nd, 1918 in Alton, Illinois, but he died only 22 years later in Manistee, Michigan on July 15th, 1940. Referred to as the Alton Giant, Wadlow reached a height of 8 feet 11.1 inches, and he was still growing at the time of his death, which was brought on by an infection. Being around three feet taller than his father Robert, Wadlow’s great height was caused by hyperplasia which led to human growth hormone issues wildly affecting Wadlow’s growth. Sadly, he developed problems with his legs, and required braces to help him to walk. By the time of his death, though, Wadlow had become a celebrity and, in 1986, a statue was erected in his honour in Alton.
