Dicephalic conjoined twins (dicephalus dipus):
- In 1811, Chang and Eng Bunker were born in Siam and exhibited around the world starting in 1829, but later settled down in the American South and led the life of plantation owners. Both died in 1874. Because of Chang and Eng, the phrase "Siamese Twins" became synonymous with conjoined twins.
