Biography Joseph Norman Lockyer (Lockyer Joseph Norman)
Born May 17, 1836 in Rugby (Warwickshire County). Educated in private schools. Since 1857 he served in the military in 1870 was secretary of the Government Commission on Science. Since 1881 - professor of astrophysics Kings College, in 1885-1913 - director of the Solar Physics Observatory in South Kensington. From 1913 he worked in a private observatory in Sidmouth (later called Lokerovskoy Observatory).
Lockyer worked spectroscopy of the Sun and stars. In 1866, spending spectral observations of the solar surface, detected changes in the spectrum during the transition from disc to stain. I explained this effect is based on the hypothesis of the dissociation of atoms at higher temperatures. Regardless of the AP Zhansena developed a method of observing prominences outside eclipse. In 1871 came to the conclusion that observed in the spectrum of prominences bright yellow line meets a new element which he called helium. Created the first spectral classification of stars. In 1870-1905 headed the eight expeditions to observe total solar eclipses. Among the works Lockyer - Work on solar physics (Contribution to Solar Physics, 1873), The role of the sun in nature (The Sun 's Place in Nature, 1897), Inorganic Evolution (Inorganic Evolution, 1900). In 1869 Lockyer founded the journal 'Neychur' ( 'Nature'). Lockyer died at the Salk Regis (Devon) 16 August 1920.
