businesses such as Cleveland Pneumatic Tool Co. Westinghouse, Sherwin-Williams, Illinois Tool Works, Ohio Brass Co., and Industrial Fasteners Institute. They also worked on technical issues such as the analysis of waters of the US for the United States Department of Health, Education, and Welfare, engineering for military applications for the US Army and high altitude research and full pressure altitude suits for the USAF. At General Technical Services, Iberall and Cardon solved problems such as physiological responses of mammals to high pressure and flow in arteries for NASA, water pollution for the Public Health Service. For US Army commands, they did research on oscillators, clothing design, technical forecasting, planning, systems science applications, cybernetics and computer applications, autonomous systems, and survival of complex systems. For the Office of Naval Research, they worked on inertial guidance systems, hydrodynamics equations, fluid dynamics. Other work included dosage radiation factors for the Atomic Energy Commission, systems science applications for the United States Department of Transportation, complex systems interactions for the National Institute of Aging, and mobile pressure suits for the US Air Force. At the UCLA Crump Institute, Iberall joined the Complex Systems Group which attracted professors from many universities and federal agencies to learn how to incorporate systems science into diverse fields. He also taught courses on the thermodynamics of living systems for chemical engineering students, which was sponsored by the Marshak Colloquium of UCLA. Contributions Space Suits and Lines of Non-Extension In 1947, Iberall began work at NBS on pressure suits for the US Air Force and the National Advisory Committee for Aeronautics. They recognized that astronauts had to be protected from expansive forces. Iberall developed one of the first space suits to solve this problem; his first approximation was to use netting (linknet) to help the suit maintain form. The ultimate solution came from an analysis of the lines of non-extension (LONE), i.e. the parts of the body that did not move much so the suit did not need special treatment there. Astronaut Scott Crossfield flew the X-15 in this suit, as did astronauts on Gemini missions between 1962-64. The Federal Government required that business interests take over further development and production for commercial applications, so the David Clark Company won the contract for space suit design and eventually took design in another direction. Years later, Dava Newman at Massachusetts Institute of Technology has her students following up on LONE as a
