Ross Honsberger

Ross Honsberger ( born 1929 in Toronto, Ontario ) is a Canadian mathematician and author of recreational mathematics.

Honsberger studied at the University of Toronto Mathematics ( bachelor's degree ) and then worked for ten years as a teacher in Toronto, before continuing his studies at the University of Waterloo ( Master's degree ). Since 1964 he is there at the Faculty of Mathematics, where he is Professor Emeritus today. He dealt with combinatorics and optimization, but in particular with mathematics education. He developed education courses, for example, on combinatorial geometry, frequently gave lectures for students and math teacher and was editor of the Ontario Secondary School Mathematics Bulletin. He wrote numerous books on elementary mathematics (geometry, number theory, combinatorics, probability theory ), and recreational mathematics (often at the Mathematical Association of America, MAA, appeared ), with his own words, the book by Hans Rademacher and Otto Toeplitz of numbers and figures as a model serves. He is also frequently treated problems from the Mathematics Olympiads and other competitions.
