Tallest man in thw world

The tallest person in history for whom there is irrefutable evidence was Robert Pershing Wadlow who stood 8 ft 11.1 inches (2.72m). He had problems standing and had an operation to fit a brace to his leg. On July 4, 1940, while making a professional appearance at the 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 worsened and on July 15, 1940, he died in his sleep. He was 22.
