88. Gia Carangi
Known For: Muse for Francesco Scavullo
Most of Carangi's dramatic life was documented in Gia starring Angelina Jolie, but before Carangi contracted and died of HIV, she was one of the world's first supermodels. Her rise to fame came suddenly when she was 17, and she told 20/20 she didn't "build into a model. [She] just sort of became one."
