Description
Charles H. Townes, the Columbia University physicist who was largely responsible for inventing the maser, took a maser and two graduate students, Leonard Alsop and Joseph Giordmaine, to the Naval Research Laboratory in Washington, D.C. There, working with Cornell Mayer and the 50-foot radio telescope at the NRL, they succeeded in capturing weak radio signals from the radio galaxy, Cygus A. This material represents that work.
