Our History

It All Began with a Curious Mind

The Gilson legacy began in the 1940s, while Dr. Warren Gilson was a faculty member at the University of Wisconsin School of Medicine. He began to design and develop specialized medical electronics and instruments for his use and that of colleagues that were not commercially available. His driving motivation was to invent and improve on lab instruments to make research easier for scientists. One of his first efforts was a cathode ray recorder—a moving paper camera that recorded images from a cathode ray tube. It was later used in cardiac catheterization labs. By the early 1950s, Dr. Gilson developed an electroencephalograph (EEG), a device that records the brain’s electrical signals for diagnosing epilepsy, strokes, and tumors. He also focused on the oxygraph, a respiration system that measures oxygen consumption.
