The tallest man in medical history for whom there is irrefutable evidence is Robert Pershing Wadlow (USA) (born 6:30 a.m. at Alton, Illinois, USA on 22 February 1918), who when last measured on 27 June 1940, was found to be 272 cm (8 ft 11.1 in) tall.
Wadlow died at 1:30 a.m. on 15 July 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.
His greatest recorded weight was 222.71 kg (35 st 1l b) on his 21st birthday and he weighed 199 kg (31 st 5 lb) at the time of his death.
