- Born in 1918, Robert is still to this day known as the tallest person in medical history. When the Pathe cameras went to film him in 1935, he was a mere 8ft 1 1/2in³. When they returned the next year, he was 8ft 4in. By the time of his death at just aged 22, he had grown to 8ft 11'' (2.7m). In this clip, he is surrounded by his family and even though his father was 6ft, none of them stand much above his waist. This video is from 1936.
