Longest recorded human bone

The longest bones ever recorded in a human were the femurs of Julius Koch (Germany), a 248.8-cm (8-ft-0.8-in) tall man who toured Europe in the late 19th century under the name "Constantine the Giant". Shortly after his death in 1902 at the age of 30, an autopsy was carried out that noted that his femurs measured some 76 cm (2 ft 5.8 in) long. By comparison, the femurs of Robert Wadlow (the tallest man ever) were estimated to be no more than 75 cm (2 ft 5.5 in) long.

There is some confusion as to Constantine's exact height as both his legs were amputated in 1901 after he developed gangrene. Curiously the 1902 autopsy report includes findings and measurements taken from his legs, suggesting that the doctors had kept them in storage until they could be reunited with the rest of his skeleton for study.
