Evans and Sutherland Computer Corporation

In 1963, Ivan Sutherland created the first interactive drawing program, Sketchpad, as part of his graduate work at the Massachusetts Institute of Technology. He later produced the first head mounted display system in 1966.

In 1968, David Evans, of the Computer Science Department at the University of Utah, talked Sutherland into leaving his post at Harvard and joining him in founding E & S. They first produced a hardware device known as a frame buffer which, as research and commercial use of graphics grew, began selling well in the early 1970s.

Sutherland left the firm in 1975, and Evans retired in the early 1990s, but E & S continues today as a major supplier of equipment and expertise in all areas of graphics and are heavily involved with training simulators in both military and commercial systems, as well as suppliers for planetariums and interactive theaters.
