5. Chang and Eng Bunker

The Bunker twins were born on May 11, 1811 in Siam, which is known Thailand. Since the two were born in Siam and were connected by a piece of cartilage at the sternum, their condition became known as Siamese twins. The brothers both had livers, but they were fused. In today’s world, the twins could have easily been separated, but 19th century medicine wasn’t fit for that type of surgery. The brothers were exhibited during a world tour after being discovered by Robert Hunter, but soon after settled down and became U.S. citizens. Both men were able to marry and even had children. The Bunker brothers are famous for being the first widely known pair of Siamese twins. In 1874 Chang had contracted pneumonia and died, but Eng was still alive. Doctors offered to separate them but Eng declined, dying three hours later.
