Gundlach made photocopying technology more practical, flexible
and affordable. As one of the first research scientists hired
by the Haloid Company, now known as the Xerox Corporation, Gundlach
was responsible for finding ways to refine and improve xerography.
The first commercial copy machines were the size of a desk, operated
slowly, and produced copies of marginal quality.
Gundlach devoted over three decades to the task of transforming
the machines into the small, robust products that revolutionized
xerography. He created three patentable inventions during his
first year at Xerox, including an idea that allowed photocopiers
to reproduce solid shapes, making copies more universally acceptable.
As xerography advanced, Gundlach invented ways to produce color
copies and use digital technology. His most lucrative patent at
Xerox enabled photocopiers to print two-colored images.
Born in Buffalo, NY, Gundlach graduated from the University of
Buffalo in 1949. He has earned more than 150 patents and was the
first Research Fellow at Xerox. Although most of his inventions
related to xerography, he has also received patents for a snow-making
machine, a comfortable backpack, and a new water-based heat pump
