A family friend and funeral home owner says Colorado's famous sex change doctor has died.
Doctor Stanley Biber of Trinidad was suffering from pneumonia but the cause of death hasn't been released. He was 82.
Mary Winter of Comi Funeral home says Biber died Monday.
In the mid-1990s Biber performed up to half the world's sex-change operations a year.
Winter says public services have not been arranged. She says Biber's family has asked for privacy.
Winter says Biber was her family's doctor for generations. She describes him as, quote, "a great man."
