ALTON, ILLINOIS: Robert Wadlow, an iconic figure in the journals of human history, towered at a remarkable height of 8 feet 11 inches (2.72 m or 272 cm) and carried a substantial weight of 199 kg (439 lbs) at the time of his passing, as officially recorded by Guinness World Records.
He held the distinction of being the tallest individual ever documented.
Robert Pershing Wadlow, also known as 'Alton Giant' and 'Giant of Illinois' born to average-sized parents, quickly began an extraordinary growth journey, reaching 5 feet 4 inches (1.63 m or 163 cm) by the age of five and towering over his father by age eight.
Undeterred by his size, he joined the Boy Scouts at 13, necessitating custom gear.
At 16, he stood at 7 feet 10 inches (2.40 m or 240 cm), and by 17, he reached 8 feet (2.45 m or 245 cm) becoming the tallest teenager ever, according to Guinness World Records.
After high school, he briefly pursued law but later joined the Ringling Brothers Circus, gaining international fame.
Tragically, at the age of 22, Robert passed away due to a septic blister on his ankle, which was caused by a poorly fitted brace.
His weight had dropped to 199 kg (439 lbs), but his height continued to increase.
His extreme height resulted from a pituitary gland condition, and though doctors identified it, they advised against surgery due to the high risks involved.
