Thomas Malin Rodgers (August 1, 1943 — April 12, 2012) was an Atlanta-based businessman and puzzle collector who is remembered as the originator of the Gathering 4 Gardner (G4G) educational foundation, first conceived in 1992. [1] He co-founded G4G with magician and toy inventor Mark Setteducati and UC Berkeley professor Elwyn Berlekamp. [2] Over the past three decades it hosted 14 biennial conferences for aficionados of the recreational mathematician and Scientific American columnist and writer Martin Gardner. [3] Rodgers also edited 6 volumes of Martin Gardner tribute books, published by AK Peters. Rodgers' personal physical puzzle collection was legendary. [4] [5]
Through his monthly Mathematical Games column and his extensive correspondence, Gardner had created a large network of fans and had achieved an almost cult-like status. [1] [6] Rodgers knew many of the other people in the ever expanding Gardner circle and a decade after Gardner stopped writing his column, Rodgers decided that a conference in his honor was merited. He managed to convince the usually shy Gardner to attend and then used Gardner's own voluminous and meticulous files to assemble a list of invitees. They called it The Gathering 4 Gardner, which was subsequently shortened to G4G. Gardner attended the first G4G in 1993 and the second, dubbed G4G2, in 1996. [6] Since then, there has been a gathering every two years up to G4G13 in 2018, and then G4G14 in 2022, delayed because of the Covid pandemic. For the first two decades G4G was sustained mostly by Rodgers with "seemingly unfettered access to his personal time and resources." [3]
By the time of G4G7 in 2006, the conference was attracting a wide assortment of people, including Mathematician Daina Taimina, gaming hobbyist Lou Zocchi, puzzle designer Wei-Hwa Huang, magic square expert Lee Sallows, puzzle historian David Singmaster, computer scientist and origamist Ron Resch, and spidron inventor Dániel Erdély—in addition to establishment mathematicians John H. Conway and Roger Penrose. [7] Rogers himself was involved in each gathering up to 2012. But he was mortally ill, and G4G10 was to be his last gathering. [3] As tradition demanded, for one day he hosted the attendees at his lavish home and Japanese gardens in north Atlanta, which was filled with his huge puzzle collection. [4] [2] He died just nine days later. [8]
Subsequent G4Gs have attracted an ever increasing array of recreational mathematicians, magicians, puzzle designers, pseudoscience skeptics, jugglers, artists, game designers, origamists, toy inventors, computer scientists, philosophers, and cognitive psychologists. [1] [8] [7]
Part of Martin Gardner's genius was that he attracted a circle of collaborators whose synergy dramatically deepened the knowledge of the subjects that Gardner was writing about. [9] Rodgers, like his mentor, carried on this tradition by founding the gathering. Neil Calkin of Clemson University in a tribute to Rodgers says: [8]
Rodgers frequently collaborated with other members of the Gardner circle to edit tribute books about him. [10] [11] [12]
Martin Gardner was an American popular mathematics and popular science writer with interests also encompassing scientific skepticism, micromagic, philosophy, religion, and literature – especially the writings of Lewis Carroll, L. Frank Baum, and G. K. Chesterton. He was also a leading authority on Lewis Carroll. The Annotated Alice, which incorporated the text of Carroll's two Alice books, was his most successful work and sold over a million copies. He had a lifelong interest in magic and illusion and in 1999, MAGIC magazine named him as one of the "100 Most Influential Magicians of the Twentieth Century". He was considered the doyen of American puzzlers. He was a prolific and versatile author, publishing more than 100 books.
Elwyn Ralph Berlekamp was a professor of mathematics and computer science at the University of California, Berkeley. Berlekamp was widely known for his work in computer science, coding theory and combinatorial game theory.
In recreational mathematics, a polydrafter is a polyform with a 30°–60°–90° right triangle as the base form. This triangle is also called a drafting triangle, hence the name. This triangle is also half of an equilateral triangle, and a polydrafter's cells must consist of halves of triangles in the triangular tiling of the plane; consequently, when two drafters share an edge that is the middle of their three edge lengths, they must be reflections rather than rotations of each other. Any contiguous subset of halves of triangles in this tiling is allowed, so unlike most polyforms, a polydrafter may have cells joined along unequal edges: a hypotenuse and a short leg.
Erik D. Demaine is a Canadian-American professor of computer science at the Massachusetts Institute of Technology and a former child prodigy.
Nobuyuki Yoshigahara was perhaps Japan's most celebrated inventor, collector, solver, and communicator of puzzles.
Edward Taylor Pegg Jr. is an expert on mathematical puzzles and is a self-described recreational mathematician. He wrote an online puzzle column called Ed Pegg Jr.'s Math Games for the Mathematical Association of America during the years 2003–2007. His puzzles have also been used by Will Shortz on the puzzle segment of NPR's Weekend Edition Sunday. He was a fan of Martin Gardner and regularly participated in Gathering 4 Gardner conferences. In 2009 he teamed up with Tom M. Rodgers and Alan Schoen to edit two Gardner tribute books.
Dennis Elliot Shasha is an American professor of computer science at the Courant Institute of Mathematical Sciences, a division of New York University. He is also an associate director of NYU WIRELESS. His current areas of research include work done with biologists on pattern discovery for microarrays, combinatorial design, network inference, and protein docking; work done with physicists, musicians, and professionals in finance on algorithms for time series; and work on database applications in untrusted environments. Other areas of interest include database tuning as well as tree and graph matching.

The fold-and-cut theorem states that any shape with straight sides can be cut from a single (idealized) sheet of paper by folding it flat and making a single straight complete cut. Such shapes include polygons, which may be concave, shapes with holes, and collections of such shapes.
In a publishing career spanning 80 years (1930–2010), popular mathematics and science writer Martin Gardner (1914–2010) authored or edited over 100 books and countless articles, columns and reviews.

Gathering 4 Gardner (G4G) is an educational foundation and non-profit corporation devoted to preserving the legacy and spirit of prolific writer Martin Gardner. G4G organizes conferences where people who have been inspired by or have a strong personal connection to Martin Gardner can meet and celebrate his influence. These events explore ideas and developments in recreational mathematics, magic, illusion, puzzles, philosophy, and rationality, and foster creative work in all of these areas by enthusiasts of all ages. G4G also facilitates a related series of events called Celebration of Mind (CoM).
