Ejnar HertzsprungBorn 8 Oct 1873; died 21 Oct 1967 at age 94. Danish astronomer who classified types of stars by relating their surface temperature (or colour) to their absolute brightness. A few years later Henry Russell illustrated this relationship graphically in what is now known as the Hertzsprung-Russell diagram, which has become fundamental to the study of stellar evolution. In 1913 he established the luminosity scale of Cepheid variable stars. |
