Engineers (IEEE) Centennial Medal in 1984 and was named an IEEE fellow in 1987. Weiss was elected to the National Academy of Engineering in 1986, based on his research into the use of ferrites in microwave components and for extensive contributions to the research, engineering, and development of military space systems. Weiss’s additional honors included election to fellowships in the American Physical Society and the International Academy of Astronautics.
The IEEE awarded Weiss its Frederik Philips Award in 1993, citing his “leadership in building electronics research and engineering organizations for the development and operation of national security space systems.” Even after his retirement from Northrop, Weiss remained active in the aerospace industry. He was appointed to serve as a council member of the California Council on Science and Technology (CCST) in 2001 and was serving his second term with the council at the time of his death. Always in touch with the latest scientific and technological advances, Weiss served on both the finance and new technologies committees of the CCST. He also served on the Defense Science Board/Air Force Scientific Advisory Board Task Force on Acquisition of National Security Space Programs, which released its findings in the so-called Young Report in 2003. The task force documented some shortcomings with space acquisition policies and urged the U.S. Air Force to continue its reform of the acquisitions process in order to field satellite systems on time and within budget.
In an interview conducted in 2005, Weiss was asked which career honor he was most proud of and he replied, “Probably election to the National Academy of Engineering, which came as a total surprise to me…. It was extremely satisfying, and of course that is one of the highest honors that any engineer can have.” Reflecting on his career with the Aerospace Corporation, Weiss recalled a year before his death that “it was an exciting time for the space program, so I enjoyed it immensely. I think I made some contributions…. And on the whole I’m very, very grateful for the opportunities that both Eberhardt Rechtin and Ivan Getting gave me. So clearly I had an impact, and that is extremely satisfying.”
