Abstract: A collaborative relationship existed between the California Institute of Technology (Caltech) and the Carnegie Institution of Washington (Carnegie) beginning in 1946, when a formal agreement was signed between the two groups of trustees. This agreement was designed to integrate Mount Wilson Observatory and the new unfinished Palomar Observatory into a single scientific entity. During the period from 1946 to 1979, much astronomical research was done at both institutions as a direct result of this collaboration. Part of this research included the first identi- fication of a radio source with an apparently stellar object by Allan Sandage of Carnegie and Thomas Matthews of Caltech in 1960, and the first identification of spectral lines at large redshift from a radio source associated with such an object by Maarten Schmidt of Caltech in 1963. This paper examines how the discovery of these objects―which came to be known as quasars―and subsequent research on them, indirectly had an
