The STG Organization
Two directives were issued on January 26, 1959. One was from the NASA Administrator T. Keith Glennan appointing Dr. Robert R. Gilruth as the Director of Project Mercury. The other was from Gilruth for all concerned at Langley, setting out the initial organization of the Space Task Group. Gilruth signed his memo as the Project Manager, rather than Director, and it was addressed to 71 people: 65 NASA employees plus 6 military personnel. It took several months for the STG to staff up, consider the tasks ahead, and figure out an initial organization. Gilruth and his staff were located in Building 58.
