Rosa & Josefa Blazek (Jan. 20th, 1878-March 30th, 1922). Rosa and Josefa hailed from Bohemia and were joined at the posterior. Since they shared a vertabra, a separation was out of the question. In 1909, Rosa shocked the world by announcing she was pregnant. She had a son and named him Franz, but it is now believed that Franz was adopted and that this was a cleverly timed publicity stunt. The sisters died within minutes of each other in 1922.
