Ed Barbeau is professor emeritus of mathematics at the University of Toronto. He was born in Toronto and received his Bachelor of Arts and Master of Arts degree from the University of Toronto before going to the University of Newcastle-upon-Tyne to gain his PhD with a thesis on functional analysis written under the supervision of F.F. Bonsall. After being assistant professor at the University of Western Ontario in London, ON for two years and a NATO research fellow at Yale University in New Haven, CT for one year, he accepted an appointment at the University of Toronto, where he has remained.

Dr. Barbeau is a life member of the Mathematical Association of America, the American Mathematical Society and the Canadian Mathematical Society, and has served all three societies on various committees, particularly having to do with mathematics education. He has published a number of books directed to students of mathematics and their teachers, including Polynomials (Springer), Power Play (MAA), Fallacies, Flaws and Flimflam (MAA) and After Math (Wall & Emerson, Toronto), has frequently given talks and workshops at professional meetings and in schools, has worked with high school students preparing for Olympiad competitions and has on five occasions accompanied the Canadian team to the International Mathematical Olympiad. He is currently associate editor in charge of the Fallacies, Flaws and Flimflam column in the College Mathematics Journal and education editor for the Notes of the Canadian Mathematical Society. He is a former chairman of the Education Committee of the Canadian Mathematical Society.

His honours include the Fellowship of the Ontario Institute for Studies in Education, the David Hilbert Award from the World Federation of National Mathematics Competitions and the Adrien Pouliot Award from the Canadian Mathematical Society.
