Bob spent one summer of his teenage years working for Wildroot, mixing Cream-Oil at a factory in Buffalo.
Gundlach attended the University at Buffalo, but was drafted just after the end of World War II following his freshman year.
After Joe Wilson, the firm's president, promised that work on military projects would never be required, Robert readily accepted the job.
He would go on to devote many years of hard work and passion into the company, contributing countless ideas and helping the small firm grow into a corporate giant.
[3] Before Robert joined the company, xerography was good at copying thin lines and characters, but could not successfully reproduce large, solid black areas.
Gundlach continued his research and experimentation in the field of xerography, developing a process that allowed many copies to be produced from a single image.
In 1955, Haloid transformed its photo-paper warehouses into showrooms for its Xerox machines and hired several hundred sales and service people.
The Xerox Corporation expanded internationally, opening subsidiaries in Mexico, continental Europe, Japan, and Australia.
These rights, along with millions of dollars spent for product development, allowed Robert Gundach to refine photocopiers undisturbed.
One of his most significant inventions was tri-level xerography, a process that allows the printing of two colors in a single pass, achieving perfect registration and greater speed than earlier methods.
He also held patents for a shadowless sundial, a snowmaking process, an extremely comfortable backpack, and a cheap 20,000 Volt electrostatic generator.
Gundlach continued to invent, and his lifetime contributions were recognized by the National Inventors Hall of Fame when he was inducted in 2005.
