Martin Gardner in the Twenty-First Century

Michael Henle is a professor of mathematics at Oberlin College. He is the author of several books including "Which Numbers are Real?" published by the MAA in 2012. Trained as a functional analysis, he also writes on combinatorial subjects and geometry. He is serving as editor of The College Mathematics Journal through to 2013. Brian Hopkins is a professor of mathematics at Saint Peter's University in Jersey City, New Jersey. He won, with Robin Wilson, the 2005 George Polya Award, edited the 2008 MAA Notes volume Resources for Teaching Discrete Mathematics, and was given the 2011 MAA New Jersey Section Award for Distinguished College or University Teaching of Mathematics. Much of his research stems from Bulgarian Solitaire, a topic popularized by Martin Gardner. Hopkins will be the editor of the College Mathematics Journal from 2014 to 2018.
