Dr. Mark W. Maier is a technical fellow at The Aerospace Corporation, Electronics and Sensors Division, an architect‑engineering firm specializing in space systems for the United States Government. His specialty is systems architecture. He teaches and consults in that subject for The Aerospace Corporation, its clients, and corporations throughout the United States and Europe. He has done pioneering work in the field, especially in collaborative systems, socio‑technical systems, and modeling, as well as significant research in advanced sensors. He is a senior member of the IEEE and one of the lead authors of ANSI/IEEE 1471 Recommended Practice for Architecture Description, which has become the basis for further international standardization. Dr. Maier received his B.S. degree in Engineering and Applied Science and an M.S. in Electrical Engineering from Caltech in 1983 and 1984, respectively. He joined the Hughes Aircraft Company in El Segundo, CA, upon graduating from Caltech in 1983. At Hughes, he was a section head responsible for signal processing algorithm design and systems engineering. While at Hughes, he was awarded a Howard Hughes Doctoral Fellowship, on which he completed a Ph.D. in Electrical Engineering, specializing in radar signal processing, at USC. At USC, he began his collaboration with Dr. Eberhardt Rechtin, who started the first systems architecture academic program. In 1992, he joined the faculty of the University of Alabama in Huntsville in the Electrical and Computer Engineering Department. As an associate professor at UAH, he carried out research in system architecture, stereo image compression, and radar signal processing. He has published several dozen journal articles and conference papers in these fields.
Dr. Eberhardt Rechtin received his B.S. and Ph.D. degrees from the California Institute of Technology (Caltech) in 1946 and 1950, respectively. He joined Caltech’s Jet Propulsion Laboratory (JPL) in 1948 as an engineer, leaving it in 1967 as assistant director. At JPL, he was the chief architect and director of the NASA/JPL Deep Space Network. In 1967, he joined the Office of the Secretary of Defense as the director of the Advanced Research Projects Agency (ARPA) and later as assistant secretary of defense for Telecommunications. He left the Department of Defense in 1973 to become chief engineer of Hewlett‑Packard. He was elected as the president and CEO of The Aerospace Corporation in 1977, retiring in 1987. After retirement from Aerospace, he joined the faculty of the University of Southern California (USC) as a professor with joint appointments in Electrical Engineering‑ystems, Industrial & Systems Engineering, and Aerospace Engineering. During his time at USC, he founded their graduate program in Systems Architecting. Dr. Rechtin was extensively honored for his engineering accomplishments. He was a member of the National Academy of Engineering; a fellow of the IEEE, AIAA, and the AAAS; and an Academician of the International Academy of Astronautics. He was further honored by the IEEE with its Alexander Graham Bell Award, by the Department of Defense with the Distinguished Public Service Award, by NASA with its Medal for Exceptional Scientific Achievement, by the AIAA with its von Karman Lectureship, by Caltech with its Distinguished Alumni award, and by NEC with its C&C Prize. His published works include Systems Architecting: Creating and Building Complex Systems, Prentice Hall, 1991; The Art of Systems Architecting with Mark W. Maier; and Why Eagles Can’t Swim: The Systems Architecting of Organizations. Dr. Rechtin passed away in 2006.
