At an alleged height of eight feet and five inches, this Ukrainian national once held the Guinness World Record for tallest man alive. Because he was never properly measured, however, he ceded the title to a 7'9" Chinese man named Bao Xishun.
In his early teens, he developed a tumor of the pituitary gland that resulted in a condition known as acromegalic gigantism.
He died in his early forties of a brain hemorrhage.
He was born and raised in Ukraine's northern Zhytomyr Oblast, an area that was then part of the USSR.
Turkish-born farmer Sultan Kosen, at a height of eight feet and three inches tall, was also a Guinness World Record holder in the "World's Tallest Living Man" category.
