George Edwin Mueller (; July 16, 1918 – October 12, 2015), was an American electrical engineer who was an associate administrator at NASA, heading the Office of Manned Space Flight from September 1963 until December 1969. Hailed as one of NASA's "most brilliant and fearless managers", he was instrumental in introducing the all-up testing philosophy for the Saturn V launch vehicle, which ensured the success of the Apollo program in landing a man on the Moon and returning him safely to the Earth by the end of 1969. Mueller also played a key part in the design of Skylab, and championed the Space Shuttle's development, which earned him the nickname, "the father of the Space Shuttle." Mueller was chairman and chief vehicle architect of the now defunct Kistler Aerospace Corp.
Early life and education George Mueller was born in St. Louis, Missouri, on July 16, 1918, to parents of German descent. His mother, Ella Florence Bosch, a high school graduate, was from Belleville, Illinois, and had been a secretary, but she never worked after marriage. His father, Edwin Mueller, was an electrician who began working as a boy and never went to high school, but later became superintendent of an electrical motor repair shop in St. Louis. Both parents were English speakers, but also spoke German; Mueller never learned German well enough to converse. He went to Benton School in St. Louis until the 8th grade, when he and his parents moved to a larger house in the country called Bel Nor, and later graduated from Normandy High School. The young Mueller enjoyed reading science fiction and, helped by his grandfather, woodworking. When he was aged 11 or 12 Mueller also built and raced model aircraft – such as gliders and rubber band model airplanes. Always curious about how things worked, he also built radios, following in the footsteps of his father. Interested in these activities, the teenage Mueller wanted to be an aeronautical engineer but discovered that where he could afford to go to school, the Missouri School of Mines and Metallurgy (now Missouri University of Science and Technology) in Rolla, Missouri, there was no aeronautical engineering department. They did offer mechanical engineering, so he enrolled in that program but found it discouraging and switched to electrical engineering. Mueller assumed he would end up working in industry and so, in his senior year, went on a tour of various suitable companies. He applied to RCA, General Electric and Emerson but when he graduated in 1939 the economy took another downturn and he, like most of the class, had no job. After applying to several graduate schools, he got an offer of a television fellowship (funded by RCA) at Purdue University. The fellowship led to his working on an early television project. Purdue was building a television transmitter for the campus, and it was the first of the kind that was using all vacuum tubes to produce the pictures. It was also the first using a cathode ray tube for display purposes. They still had mechanical disks for scanning but were trying to develop an all-electronic approach.
Bell Labs Near graduation, he applied for a research job at Bell Labs, which he received. After a year to establish himself there, he married Maude Rosenbaum, whom he had met in St. Louis and dated while at Purdue. The work Mueller did at Bell Labs deferred him from being drafted into the military during World War II. He initially researched orthicon technology, but, as Bell Labs geared up for war, it later became heavily involved in airborne radar technology. As the war progressed, his group was given the task of building the first airborne radar for Bell. Ultimately, the radar designed by MIT was chosen over the Bell Labs system, but not until after Mueller became spectacularly sick while flight testing Bell Labs' radar on a visit to Wright Airfield in Ohio. He continued his work on magnetrons and said he came close to co-inventing the transistor. If he and his co-workers had placed their contacts on a single crystal of zircon rather than working with multiple crystals, they would have beaten Shockley's team, also at Bell Labs.
PhD and Ramo-Wooldridge Mueller increasingly believed that to move up in the hierarchy of the Labs he would need a PhD, and he began working towards this goal on a part-time basis at Princeton University, getting up every morning at around 5 o'clock and driving to Princeton to take a couple of courses before driving back down to Holmdel to work all day at Bell Labs. In 1946 a colleague at the Labs: Milton Boone - a professor from Ohio State University on leave at Bell Labs during the war, encouraged Mueller to help set up a vacuum tube lab and run the communications group at Ohio State. Moving to Columbus, Mueller taught electrical engineering and the new field of system engineering, and continued his research, focusing his PhD thesis on dielectric antennas. Upon obtaining his doctorate in physics in 1951, he became associate professor of electrical engineering. Ramo-Wooldridge Corporation, later part of TRW, recruited him and he took a one-year sabbatical in 1953. A consultant to Ramo-Wooldridge, Mueller got involved in the review of radar designs and the Bell Labs radar for the Titan rocket (which was originally radio-guided). Mueller was peripherally involved with some of the developments of the inertial systems and generally began to help out wherever there was a problem. Mueller admitted in 1987 that at this time he did not know anything about missiles. After returning from his sabbatical year to Ohio State, Mueller taught but was also retained as a part-time consultant to R-W. In 1957 he joined Ramo-Wooldridge full-time as director of the Electronics Laboratories. This Laboratory soon merged with the mechanical group, and then Mueller became deputy leader of this larger research and development organization. He was also program director for the Pioneer program and later took over as head of R&D [Research and Development]. The Thompson Products Company bought R-W and merged it into what became TRW. While working on missile systems Mueller became convinced that all-up testing was essential as "you don't want to be testing piece-wise in space. You want to test the entire system because who knows which one's going to fail, and you'd better have it all together so that whatever fails, you have a reasonable chance of finding the real failure mode, not just the one you were looking for."
