Wollaston, William Hyde (1766-1828), an English chemist and physicist. In 1802 Wollaston discovered the dark lines in the solar spectrum (later named Fraunhofer lines). The following year he invented a method for producing platinum in malleable form and discovered two metallic elements: palladium and rhodium. In 1809 Wollaston invented the reflecting goniometer, a device for determining the shapes of crystals. Another of his inventions, in 1812, was the camera lucida.
He may have been born in Brooklyn, but Carl Sagan was gunning for the stars as soon as he arrived in this world. Get to know the scientist whose infectious delight in the universe still holds us spellbound.
