The Radio and Geoastronomy Division was formed in fiscal year 1979 by the combination of two existing divisions: Radio Astronomy and Geoastronomy. The first of these two was formed in 1973 under the reorganization of the Smithsonian Astrophysical Observatory (SAO) conducted by new director George B. Field. Arthur Edward Lilley (b. 1928), professor of radio astronomy at Harvard University, was appointed associate director of the observatory in charge of this division, a position he retained through the merger until the end of calendar year 1986. The Division of Geoastronomy was formed in 1970 under the direction of George Charles Weiffenbach (b. 1921), who joined the staff in 1969. At the time this was one of the few divisions into which the observatory was divided, and it retained its identity under Field's 1973 reorganization. Weiffenbach retained the directorship until 1976, when John C. Gregory took over as acting associate director until the merger of the two divisions.
