The Environmental Research Institute of Michigan (ERIM) was a research institute at Ann Arbor, Michigan, founded in 1972. The institute contributed to the development of remote sensing, radar, and holography. ERIM grew out of a military and environmental research arm of the University of Michigan, the Michigan Aeronautical Research Center, later known as the Willow Run Research Center. A for-profit enterprise, ERIM International, split off from it in 1997. This was successively acquired by Veridian Corporation, by General Dynamics - moving to Ypsilanti - and in 2014 by MacDonald, Dettwiler and Associates (MDA). Meanwhile, the remaining non-profit portion became the Altarum Institute in 2001. Part of Altarum was in 2006 merged into the Michigan Tech Research Institute (MTRI), conducting environmental and remote sensing research, while health systems research continues at Altarum Institute. History The Environmental Research Institute of Michigan (ERIM) began as Willow Run Laboratories in 1946, but was established as a private not for profit research institute when it formally separated from the University of Michigan in 1972. ERIM contributed to the development of remote sensing for environmental and military applications. Much of the laboratory's early history is not publicized because ERIM and its predecessor organizations were developing remote sensing and surveillance systems to collect military intelligence from aircraft and satellites. Willow Run Laboratories Prior to Willow Run Laboratories's establishment in 1946, with the Cold War just beginning, the War Department was concerned about keeping the U.S. in the forefront of applied science. University researchers newly returned from WWII service were anxious to use their expertise to address those concerns. At the University of Michigan's College of Engineering, Professors William Gould Dow and Emerson W. Conlon approached Wright-Patterson Air Force Base scientists with their proposal to conduct a large-scale research project. The project was designed to prove the feasibility of what would later be referred to as an antiballistic missile system. The proposal was accepted, called WIZARD, and it was this contract that gave birth to ERIM's first predecessor organization, the Michigan Aeronautical Research Center (MARC). During the Vietnam War, protesters at the University of Michigan forced the University to sever formal ties with Willow Run Laboratories. Research from ERIM provided technology for military surveillance, as well as information and models for better prediction and understanding of floods, fires, agricultural crops and remotely sensed information, including studies of the Bering Glacier.
