(with honor), M.S., and Ph.D. degrees in electrical engineering from the California Institute of Technology, Pasadena, in 1962, 1963, and 1969. He received the degree of Doktoringenieurs Ehren halber (Dr.-Ing. E.h.) (Doctor of Engineering honoris causa) from the Otto-von-Guericke-University Magdeburg, Germany, in 2004. He was stationed at the Air Force Research Laboratory, Directed Energy Directorate (formerly Phillips Laboratory, formerly Air Force Weapons Laboratory), Kirtland AFB, Albuquerque, NM, from 1963 to 1967 and from 1968 to 1971. From 1971-2005 he served as a civil servant with a position as Senior Scientist at the Air Force Research Laboratory. Since 2005 he was a distinguished research professor at the University of New Mexico, Department of Electrical and Computer Engineering. He received the Air Force Research and Development Award (1970), AFSC Harold Brown Award (1990), and Air Force Research Laboratory Fellow (1996). He edited several interagency note series on EMP and related subjects, received the Richard R. Stoddart award of the IEEE EMC Society (1984), and the John Kraus Antenna Award of the IEEE Antennas and Propagation Society (2006). He was a Life Fellow of the IEEE, recipient of the 1987 Harry Diamond Memorial Award, and recipient of the 2007 IEEE Electromagnetics Field Award. Dr. Baum published five books: Transient Lens Synthesis: Differential Geometry in Electromagnetic Theory, Electromagnetic Symmetry, Ultra-Wideband, Short-Pulse Electromagnetics 3, Detection and Identification of Visually Obscured Targets, and Ultra-Wideband, Short-Pulse Electromagnetics 8. He was a member of Commissions A, B, & E of the U.S. National Committee of URSI and founder and president of the SUMMA Foundation. Fred M. Tesche: "Working with Carl was not easy, but it was always rewarding. He had expertise in a wide array of technical subjects, ranging from nuclear physics to system-level testing... Carl's interests were much wider than just in the technical domain. He was well versed in history and philosophy. He played the piano and composed classical music... And he created the SUMMA foundation to further some of these interests." Kelvin Lee: "Carl built many, many simulators. First one called ALECS, then ARIES and then ATLAS. I think he named all these after Greek God's names... Carl was a very good experimentalist. I would say he was first rate engineer... He document everything." Robert Gardner: "Carl's job was what Carl decided it was going to be. He never paid much attention to his managers. He just kind of did what he wanted to do... His notoriety, if you will, came out when TRESTLE was built." John Norgard: "Music was his other passion. Not only did he play the piano very well, he composed. Mostly classical music... In the beginning he was just a research machine... But then later... I realized he was human after all." Dave Giri: "In 2009, during the last short course in Switzerland, in his charming, pompous way, that giant of a man 'knighted' me. Carl gently placed a medieval sword upon my shoulder and said, 'I want you to continue the tradition of the High-Power Electromagnetics short course and I want you to keep The Notes Series alive.'" Ira Kohlberg: "If you weren't called 'Stupid' by Carl you were a nobody... It wasn't a put-down: Once he said that to you, you knew you were one of his friends... Carl's human qualities were just outstanding and he wouldn't let anybody down." Larry West: "Carl was too brilliant to ignore... The Notes series was unique in that it was edited by the foremost electromagnetic scientist in the world: It was free and the Notes came out quickly... Researchers recognized the authenticity of the Notes series and its high degree of technical content and they just referenced it." John H. Darrah: "Carl was a nice guy. He had his oddities but he was a genius — quality guy... He was lecturing most of the time... I never saw him wrong on boundary value problems in electromagnetic theory. He was always right." Bill Prather: "Carl was a practical person. All of his theories, his antennas, even the BLT, for example, were engineered toward applying them toward a practical problem..." - Sonata for Piano No 1 in C Minor Opus 14 - Brass Quintet No 1 in B Flat - String Quartet No 1 in G Minor - Woodwind Quintet No 1 in B Flat Dr. Baum recounts his early life, schooling at Christian Brothers Academy in Syracuse, attending Caltech, and arriving at the Air Force Weapons Laboratory (AFWL) at Kirtland AFB in June 1963. He discusses the early Cold War challenges of high-altitude and surface EMP, working with figures like Conrad Longmire, Lt. W. R. Graham, and Dr. Ralph Partridge of Los Alamos. Baum created specialized EMP sensors (PMD, CML, OML) and conceived and developed major EMP simulation facilities including ALECS, ARIES, and ATLAS I (the Trestle)—the world's largest wooden structure designed by analogy to transcontinental railroad trestles to test aircraft in simulated nuclear electromagnetic environments.
