Newcomb Cleveland Prize

Halton C. Arp, a Carnegie Institution of Washington staff member at the Mount Wilson and Mount Palomar Observatories, was awarded the Newcomb Cleveland Prize of the American Association for the Advancement of Science in December. The $1000 prize, which is awarded annually for a “noteworthy paper, representing an outstanding contribution to science”, was presented to Dr. Arp during the 1961 AAAS meeting in Denver for his paper, “The Stellar Content of Galaxies”, which he delivered as the Astronomical Society’s Helen B. Warner Lecture at the AAAS meeting in New York City in 1960. The paper summarized observations made by himself and others in recent years on the formation and evolution of stars and galaxies and the relationships among them, indicating that stars, and possibly galaxies, vary widely in chemical composition, the stars in the oldest clusters generally being the most deficient in metals.
