I was thinking the same thing recently...

anyway:

Adam Rainer (1899–1950) is the only person in recorded history ever to have been both a dwarf and a giant.

Rainer was born in Graz, Austria. In 1920 at age 21, his height was 3 feet 10.5 inches. Then, likely as a result of a pituitary tumor, he had a dramatic growth spurt so that by 1931 he had reached a height of 2.18 m (7 ft 1 in). As a result of his extreme growth, he became bedridden for the rest of his life.

When he died in 1950 he had reached a height of 2.34 m (7 ft 8 in). His feet measured 13.1 inches, and his hands 9.4 inches. He weighed only 241 pounds. As of today, he is the only person in the world who was classified as a dwarf and a giant.
