Stanley Biber (1923–2006) was a surgeon in Trinidad during the twentieth century who specialized in sex reassignment surgeries. His clinic, one of the first in the country to offer sex reassignment surgeries, grew in reputation thanks to its compassionate treatment of transsexual patients. Biber’s life and work represent one piece of America’s evolving views on gender identity and sexuality, and his legacy remains that of a pioneering influence in medicine. Although Trinidad is no longer colloquially known as the “sex-change capitol of the world,” Biber’s practice indelibly shaped the history of that town and of a nationwide movement.
