Arthur S. Iberall (June 12, 1918 – December 8, 2002) was an American physicist/hydrodynamicist and engineer who pioneered homeokinetics, the physics of complex, self-organizing systems. He was the originator of the concept of lines of non-extension on the human body which was used to create workable space suits. Biography Arthur S. Iberall was born in New York City. His mother, Anna Katz, immigrated to the United States from Kaunas, Lithuania. His father, Benjamin Iberall, immigrated from Warsaw, Poland. He had one sibling, psychologist Rosalind Rothman. He married Helene Rubenstein (1913-2016) in 1940, and they had four daughters, Eleanora I. Robbins, Penni I. Rubin, Thea Iberall, and Valerie I. O'Connor. Iberall studied at City College of New York, where he received a BS in physics in 1940 and then continued by studying mechanical engineering. From 1942-1945, he worked on an MS under George Gamow and Edward Teller at George Washington University. From 1941 to 1953, Iberall worked at the National Bureau of Standards in Washington, DC. In 1953, he left government work and worked in the private sector at ARO (1954) and the Rand Development Corporation (1954-1964). In 1964, he started General Technical Services with Samuel Z. Cardon in Upper Darby, Pennsylvania. In 1976, he was awarded an honorary Doctor of Science from Ohio State University in recognition of his achievements in interdisciplinary scientific research. At the invitation of F. Eugene Yates, Iberall joined the UCLA Crump Institute for Medical Engineering. From 1981 to 1985, Iberall was a Crump Visiting Scholar where he did research and taught. In 1991, he retired and started publishing with Cri-de-Coeur Press. Iberall died in 2002 from congestive heart failure. Work Under the leadership of William G. Brombacher at the National Bureau of Standards, Iberall worked on instrument theory, safety equipment, and measurement problems such as the physics of the atmosphere. At that time, the US Navy and US Air Force were creating aircraft that could travel further and further into the upper atmosphere. Pilots were being affected at the higher altitudes, which led to funding of studies of human physiology in order to understand how the body responds to high G forces and reduced oxygen. He also worked on the development of a new breathing apparatus that led to undersea scuba innovations. At the Rand Development Corporation, Iberall worked on engineering and physics problems. Along with chemist Samuel Z. Cardon, he solved technical problems for
