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.
Wadlow's greatest recorded weight was 222.71 kg (35 st 1 lb) on his 21st birthday
and he weighed 199 kg (31 st 5 lb) at the time of his death. His shoe size was 37AA
(47 cm, 18½ in long) and his hands measured 32.4 cm (12¾ in) from the wrist to the tip
of the middle finger. He wore a size 25 ring. His arm span was 2.88 m (9 ft 5¾ in) and
his peak daily food consumption was 8000 calories.
At the age of nine, he was able
to carry his father Harold F. Wadlow, later Mayor of Alton, who stood 1.8 m (5 ft 11 in)
and weighed 77 kg (170 lb), up the stairs of the family home.
