## Bio

Born 7 March 1792, John Frederick William Herschel grew up in the shadow of his father William, who had discovered Uranus. He ranged across disciplines: mathematics, astronomy, chemistry, invention. He gave names to seven moons of Saturn and four around his father's planet, originated the Julian day system that astronomers still keep time by, and pioneered experimental photography — including the blueprint process. His investigations ran to colour blindness and ultraviolet's chemical effects. In 1831 his Preliminary Discourse laid out an inductive method for science, shaping how theory should rise from experiment. He died 11 May 1871, a baronet who had touched more fields than most specialists ever see.
