Portrait of Sir Norman Lockyer (1836-1920), British astronomer and discoverer of helium. Lockyer started his career as a civil servant, later turning to astronomy. He used recently- introduced methods of spectral analysis to study the Sun. He discovered an unknown element in the Sun by such spectrographic analysis, naming it helium (from Greek helios = Sun). In later life, he founded the Science Museum in London, and the revered scientific journal Nature which he edited for over 50 years.
