Nancy Blachman

Nancy Blachman, Chair
Founder, Julia Robinson Mathematics Festival

Nancy Blachman’s love of mathematics and puzzles goes back to her high school days when she took George Polya’s short course in mathematical logic, did a research project on continued fractions, and participated in the Saint Mary’s Math Contest, which was held at Saint Mary’s College in Moraga, California. These experiences taught her that it was more fun to learn by discovery than to be told how to solve problems or just apply formulae. She subsequently earned degrees in mathematics, computer science, and operations research from the University of Birmingham (UK), Stanford, and UC Berkeley, respectively. She has written several books on Mathematica, in 2003 created Google Guide, and in 2007 founded the Julia Robinson Mathematics Festival, which inspires students to explore the richness and beauty of mathematics in a cooperative environment.

Erik Demaine

Erik Demaine, President
Professor in Computer Science at the Massachusetts Institute of Technology

Erik Demaine’s research interests range throughout algorithms, from data structures for improving web searches to the geometry of understanding how proteins fold to the computational difficulty of playing games. He received a MacArthur Fellowship as a “computational geometer tackling and solving difficult problems related to folding and bending—moving readily between the theoretical and the playful, with a keen eye to revealing the former in the latter”. He appears in the recent origami documentary Between the Folds, cowrote a book about the theory of folding (Geometric Folding Algorithms), and a book about the computational complexity of games (Games, Puzzles, and Computation). Together with his father, Martin Demaine, his interests span the connections between mathematics and art, including curved-crease sculptures in the permanent collections of the Museum of Modern Art in New York, and the Renwick Gallery in the Smithsonian.

Colm Mulcahy

Colm Mulcahy, Vice President
Professor of Mathematics at Spelman College, Atlanta

Colm Mulcahy bought his first Martin Gardner book in 1975, and had the pleasure of getting to know the man himself starting in 2000. His own book Mathematical Card Magic: Fifty-Two New Effects on original mathematical card principles was published in 2013. He has written for, Huffington Post, Aperiodical and Scientific American.

Bob Crease

Robert Crease, Secretary
Chair of the Department of Philosophy at Stony Brook University

Robert P. Crease has written, translated, or edited over a dozen books on history and philosophy of science, and is Past Chair of the Forum for History of Physics of the American Physical Society. He is Co-editor-in-chief of Physics in Perspective, and for 18 years he has written a column, “Critical Point,” on the historical and philosophical dimensions of science for Physics World. His next book is The Workshop and the World: What Ten Thinkers Can Tell Us about Science and Authority, to be published by Norton in March.  Website:

James Gardner

James Gardner, Board Member
Professor at the University of Oklahoma

Jim is a Professor of Special Education at the University of Oklahoma, with interests in universal design for learning and assistive technologies. He manages the intellectual property of Martin Gardner, and is currently involved in a variety of projects with publishers and organizations to continue the legacy of his father’s work.

Jade Vinson

Jade Vinson, Treasurer
Founder, Talking Leaves NC

Jade Vinson, founder of Talking Leaves NC, has worked in a range of applied fields including cryptography, genomics, finance, and AI. He earned his PhD at Princeton University, where he studied random matrices. He serves on the board of the National Museum of Mathematics and also supports the Bridges Organization.

Vickie Kearn, Board Member
Former Mathematics Editor, Princeton University Press

Prior to retiring in April 2019, Vickie was the executive editor for mathematics and computer science at Princeton University Press for 18 years. Vickie always loved numbers and puzzles as a young child but it was her high school math teacher who really lit a spark by showing her the connections between the people and the equations. Every number has a story and a person behind it. She taught school for 8 years before beginning her 42 year career in publishing. Her goal has always been to connect every bit of math to the person responsible for it or to a use for it. No one should fear math and just as no one hates music, no one should hate math. Her goal as a member of the board is to continue to promote the joy Martin Gardner brought to recreational math.

Nick Baxter

Growing up solving puzzles and exploring the recreational side of mathematics, Nick was inspired largely by the many books from Martin Gardner. Nick regularly attends the annual International Puzzle Party, and serves as the USA president of the International Puzzle Collectors Association. He is also director of the annual US Puzzle Championship, and has led Team USA as a contestant or captain to 14 titles over the 28-year history of the World Puzzle Championship. He recently qualified for the Red Bull Escape Room World Championship. Nick lives in SF Bay Area, enjoying the active community of local puzzlers, mathematicians, and escape rooms. He has been fortunate enough to attended all 13 Gathering for Gardner conferences.


Mark Burstein

An erstwhile software engineer and now book editor by profession, Mark Burstein, a noted scholar, collector, and president emeritus of the Lewis Carroll Society of North America, has edited, introduced, or contributed to twenty books on Lewis Carroll, including editing and art-directing the 150th Anniversary Edition of Gardner’s Annotated Alice and the trade edition of Alice’s Adventures in Wonderland illustrated by Salvador Dalí. He also produced A Bouquet for the Gardener: Martin Gardner Remembered, which consists of a biography, remembrances, tributes, a bibliography, and a Festschrift by such writers as Doug Hofstadter, David Singmaster, Scott Kim, and Ray Smullyan.


George Hart

is a sculptor and applied mathematician who demonstrates how mathematics is cool and creative in ways you might not have expected. Whether he is slicing a bagel into two linked halves or leading hundreds of participants in an intricate geometric sculpture barn raising, he always finds original ways to share the beauty of mathematical thinking. Hart co-founded the Museum of Mathematics in New York City and developed its initial set of hands-on exhibits. He also makes videos that show the fun and creative sides of mathematics.


Hirokazu Iwasawa

(a.k.a. Iwahiro) is a notable Japanese puzzle designer awarded several highest prizes in the Nob Yoshigahara Puzzle Design Competition. He has written or translated (into Japanese) about twenty books on mathematics, puzzles, and philosophy, including translation of The New Martin Gardner Mathematical Library series, four of which have been published so far. Professionally, he is one of the most noted actuaries in Japan. He gives lectures on modern actuarial science in different forms including regular classes at the Institute of Actuaries of Japan, Tokyo University, and Waseda University.
