  • "The original Man, the Individual first created, was bi-sexual." -Aids to Reflection, 1824

    Coleridge was the first to use the word in print, but not in the same way it's used today. He used it to mean that humans are born with both masculine and feminine characteristics, and "learn" to act masculine or feminine. The word wasn't used to describe someone with attraction to either gender until the 1890s.
