what was the world's tallest man?
By his first birthday, Robert Wadlow weighed 45 pounds and stood 3 feet, 3.5 inches. He kept growing, towering over his father at age eight. At 13 years old and 7 feet, 4 inches, he was the worldâs tallest Boy Scout. Wadlow was a quiet and mild-mannered young man, which led to him be called a âgentle giant.â He enjoyed photography and playing guitar â until his hands grew too large to do either. A hyperactive pituitary gland fueled his extraordinary growth.
