Leo Goldberg


US astrophysicist who carried out research into the composition of stellar atmospheres and the dynamics of the loss of mass from cool stars. His main subject of research was the Sun.
Goldberg was born in Brooklyn, New York, and studied at Harvard, where, after 23 years at the University of Michigan, he was professor 1960-73 and director of Harvard College Observatory 1966-71. From 1971 to 1977 he was director of the Kitt Peak National Observatory in Arizona.
At Harvard, Goldberg and his colleagues designed an instrument that could function either as a spectrograph or as a spectroheliograph (a device to photograph the Sun using monochromatic light). This formed part of the equipment of Orbital Solar Observatory IV, launched 1967. He has also carried out research on the temperature variations and chemical composition of the Sun and of its atmosphere, in which he succeeded in detecting carbon monoxide.
