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.

Wadlow died at 1:30 a.m. on July 15, 1940, in a hotel in Manistee, Michigan, as a result of a septic blister on his right ankle caused by a brace, which had been poorly fitted only a week earlier. He was buried in Oakwood Cemetery, Alton, in a coffin measuring 3.28 m (10 ft 9 in) long, 81 cm (32 in) wide and 76 cm (30 in) deep.
