Cheswick has worked on (and against) operating system security for over 35 years. He has worked at Lehigh University and the Naval Air Development Center in system software and communications. At the American Newspaper Publishers Association/Research Institute he shared his first patent for a hardware-based spelling checker, a device clearly after its time.

Ches is popular public speaker and has given keynote presentations in a couple dozen countries.

Ches has a wide interest in science and medicine. In his spare time he reads technical journals, hacks his home, and develops exhibit software for science museums. He eats very plain food---boring by even American standards.
