Bondy was dismissed from his tenured position at the University of Waterloo in 1995, after 25 years in which he had been a major contributor to the renown of the University's Department of Combinatorics and Optimization. The reasons for his dismissal centered on ''"Bondy's acceptance of a teaching post in France, and the acceptability of someone who is on UW's faculty payroll holding a full-time job elsewhere."'' Protesting the decision, Paul Erdős returned his honorary doctorate to the University of Waterloo, and
