William Eugene "Bill" Stumpf (March 1, 1936 – August 30, 2006) was a designer for Herman Miller who helped design the Aeron, Embody and Ergon chairs.
It was at the University of Wisconsin-Madison where Stumpf, working with specialists in orthopedic and vascular medicine, conducted extensive research into ergonomics, specifically in the way people sit.
In 1974, Herman Miller commissioned him to apply his research to office seating.
