Feodor Machnow (1878 - 1912) also known as the Russian Giant. His tallest official measurement of 7 feet, 10 inches was taken at the age of 16. However, his wife claimed that he added height afterward, and eventually reached a towering 9 feet, 3 inches. Skeptics point out that Machnow was known for wearing a gigantic Russian Cossack fur hat and tall boots, which might account for the discrepancy.
