  • Hennig Brand

    He was searching for a way of extracting gold from the body when he hit upon what seemed like a bright idea, a gold-colored liquid in plentiful supply - urine.
    He distilled the urine down to a paste and then heated it at a phenomenal temperature for several days, creating a fiery substance - phosphorous.
    Brand called his discovery "Icy Nocta Luca."
  • Joseph Priestley

    He was fascinated by fixed air and mixed it with water, and so invented the first fizzy drink.
    He became the first professional, salaried chemist.
    He put mercuric oxide in a test tube to collect any gas it might give off when he heated it, heated up the powder, and found oxygen.
    He concluded that his air must be without phlogiston and called it dephlogisticated air.
  • Humphry Davy

    Harnessed electricity to rip apart a caustic chemical called potash. Discovered violent potassium.
