The tallest man in medical history for whom there is irrefutable evidence is Robert Pershing Wadlow. He was born at Alton, Illinois, USA, on February 22, 1918, and when he was last measured on June 27, 1940, was found to be 2.72 m (8 ft 11.1 in) tall.

How about that? Haven't heard of this guy before, would be pretty cool to be 2,72m !
