Hey, have you ever seen the World’s Talest Man? Well, his name is: Robert Wadlow. Robert Pershing Wadlow was born in Alton in 1918, a normal-size baby, but soon his perky pituitary gland triggered abnormal growth. At the age of 13, already 7 ft. 4 in., he was proclaimed the world’s biggest Boy Scout. And he kept getting bigger…. he eventually topped out at 8 ft. 11.1 inches.
