Jordan Stuart Ellenberg (born 1971) is an American mathematician working as a Professor of Mathematics at the University of Wisconsin–Madison. His research covers a wide variety of topics within arithmetic geometry. He received both the A.B. and Ph.D. from Harvard University, where he was a two-time Putnam Fellow.
In addition to his research articles, he has authored
- a novel, The Grasshopper King, which was a finalist for the 2004 Young Lions Fiction Award, and which is published by Coffee House Press;
- the Do the Math column in the online journal Slate; and
- various articles on mathematical topics in The New York Times, The Washington Post, The Boston Globe, Wired, Seed, and The Believer.
Ellenberg was a child prodigy who taught himself to read at the age of 2 by watching Sesame Street. His mother discovered his ability one day while she was driving on the Capital Beltway when her toddler informed her: "The sign says `Bethesda is to the right.'" In second grade, he helped his teenaged babysitter with her math homework. When he was seven, Ellenberg was discovered by Eric Walstein, a teacher at the nearby Montgomery Blair High School. Walstein took Ellenberg under his wing and oversaw his mathematical development. By fourth grade, he was participating in high school competitions (such as the American Regions Mathematics League) as a member of the Montgomery County math team. And by eighth grade, he had started college-level work. He was part of the Johns Hopkins University Study of Mathematically Precocious Youth longitudinal cohort. He scored above 700 on the Math portion of the SAT-I exam at, or before the age of 13. When he was in eighth grade, he took honors calculus classes at the University of Maryland; when he was a junior at Winston Churchill High School, he earned a perfect score of 1600 on the SAT; and as a high school senior, he placed second in the national Westinghouse Science Talent Search. He participated in the International Mathematical Olympiads three times, winning two gold medals in 1987 and 1989 (with perfect scores) and a silver medal in 1988. He was also a two-time Putnam fellow (1990 and 1992) while at Harvard.
