Ladan and Laleh Bijani (January 17, 1974 – July 8, 2003) were Iranian conjoined twin sisters. They were joined at the head and died immediately after their complicated surgical separation. Coincidentally, the twins were born 100 years to the day of the deaths of Chang and Eng Bunker, also conjoined twins, famously known as the “original” Siamese twins.

They wanted to see each other face to face, they said, and to pursue independent lives. And so Ladan and Laleh Bijani, 29-year-old Iranian twins who were born joined at the head, asked doctors to go ahead with a risky operation to separate them.
