Arthur Benjamin has taught at Harvey Mudd College, where he is Professor of Mathematics and past Chair, since 1989.


In 2000, he received the Haimo Award for Distinguished Teaching by the Mathematical Association of America, and served as the MAA’s Polya Lecturer from 2006 to 2008. 

His research interests include combinatorics and number theory, with a special fondness for Fibonacci numbers. Many of these ideas appear in his book (co-authored with Jennifer Quinn), Proofs That Really Count: The Art of Combinatorial Proof, published by MAA. In 2006, that book received the Beckenbach Book Prize by the MAA. Professors Benjamin and Quinn were the editors of Math Horizons magazine from 2004 through 2008. 

Arthur has created four DVD courses for The Great Courses: “The Joy of Mathematics,” “Discrete Mathematics,” “The Secrets of Mental Math,” and “The Mathematics of Games and Puzzles.” He is a past winner of the American Backgammon Tour. 

Arthur is also a magician who performs his mixture of math and magic to audiences all over the world, including the Magic Castle in Hollywood. 

He has demonstrated and explained his calculating talents in his book Secrets of Mental Math and on numerous television and radio programs, including The Today Show, CNN, and National Public Radio. He has been featured in Scientific American, Omni, Discover, People, Esquire, New York Times, Los Angeles Times, and Reader’s Digest, which named him “America’s Best Math Whiz” in 2005.
