Chang and Eng Bunker (May 11, 1811 – January 17, 1874) are widely considered the most prominent conjoined twins in history, and are even the source of the colloquial term “Siamese Twins”, though that terminology is largely frowned upon for being largely incorrect and racist.
Chang and Eng have one of the most interesting stories ever heard. They started as slaves but eventually became slave-owners, finally losing their slaves again after the Civil War. The full-story of Chang and Eng is not only interesting because of their unique biology, but also for the crazy and complicated lives led by the brothers.
