The Gentle Giant
Robert Wadlow, the world's tallest man, reached 8 ft. 11 inches and 438 pounds at death. He wore size 37AA shoes, and his fingers measured 12.5 inches from wrist to top of middle finger. He grew normally until the age of 4, and from then on never stopped growing. His growth was due to a tumor in his pituitary gland that caused overproduction of growth hormones.
