Sandor Lehoczky, Richard Rusczyk, and Sam Vandervelde met during the summer of 1987 when they attended the Math Olympiad Summer Program at the US Military Academy. Their mutual interests (such as playing pool, seeking adventure, and guzzling mandarin orange Slice) led them to become fast friends. Upon graduating from high school they formed the partnership Greater Testing Concepts and began producing The Mandelbrot Competition. After many years of creating mind-bending questions and writing the two volume best-seller The Art of Problem Solving, Sandor is seeking his fortune in the world of finance and beyond while Richard oversees the world-famous web site by the same name, Art of Problem Solving.

Not surprisingly, Sam Vandervelde enjoyed taking math contests while in high school and college. He is proud of winning ARML his senior year while attending Amherst County High School, as well as being selected for the 1989 IMO team which took 5th place in West Germany later that summer.

Dr. Vandervelde received his doctoral degree from the University of Chicago in June 2004 and is currently on the math faculty at St. Lawrence Univesity, New York. He teaches number theory, college geometry, combinatorics, and coaches the Putnam team, among other things. He also hopes to meet many past Mandelbrot participants and work together with them developing fascinating research projects. His mathematical interests include number theory, graph theory, and integer partitions. He also enjoys coaching little league soccer and recently completed his first textbook, an introduction to mathematical reasoning and writing proofs.

He resumed his graduate studies in 2001 after a five year stint teaching mathematics at The Roxbury Latin School, a private boys school in Boston for grades seven through twelve. He continues to engage secondary school students in mathematics during the summers at MathPath, an excellent residential program for middle school students.

As if dreaming up fiendishly difficult questions for the Mandelbrot Competition were not enough to keep him occupied, Sam is also the proud father of two not-so-little boys, currently finishing up first and fourth grade. His older son's latest exploits include hitting (hard foam) baseballs over his neighbor's garage and practicing the baritone horn at odd hours. Meanwhile the younger one has made it all the way to Harry Potter and the Prisoner of Azkaban and is now learning the finer points of playing cribbage.
