Ellen Kaplan received her B.A. and (after a year as a Fulbright student at the Friedrich-Wilhelms-Universität in Bonn) her M.A. from Harvard, in Classical Archeology, before pursuing a career as a teacher. Initially teaching Greek, Latin, history and biology, she switched to mathematics, which so inspired her that she co-founded the renowned Math Circle with her husband. They have since co-authored The Art of the Infinite and Out of the Labyrinth: Setting Mathematics Free about their Math Circle – which will be published in January 2007. Extending the family’s mathematical tradition, Ellen has illustrated her husband’s book The Nothing That Is and, together with son Michael, has co-written Chances Are . . . Adventures in Probability.
