Dr. Theodore W. Hall graduated from the University of Michigan in 1981 with a professional Master of Architecture degree (M.Arch.), but as a de facto computer programmer – beginning with computer-aided architectural design, building information modeling and system analysis, morphing into general 3D geometric modeling and visualization, and culminating in virtual reality. In his “day job” he now works at the University of Michigan as a virtual-reality visualization specialist, developing software and providing consultation for projects throughout the University. When his first programming job ended with the project funding in 1986, he entered the Doctoral Program in Architecture (Arch.D.) and ultimately produced a dissertation on “The Architecture of Artificial-Gravity Environments for Long-Duration Space Habitation” in 1994. He was a founding member of the Space Architecture Technical Committee (SATC) in the American Institute of Aeronautics and Astronautics (AIAA), and chaired the committee 2010-2014. He also organized and chaired the space-architecture sessions at the International Conference on Environmental Systems (ICES) 2007-2010 and 2013-2014. He regards space architecture as his “expensive hobby,” and continues to attend conferences and publish occasional papers on the subject of design for artificial gravity.
