## Early life

Elkies attended Stuyvesant High School in New York City for three years[2] before graduating in 1982.[3][4] In 1981, at age 14, he was awarded a gold medal at the 22nd International Mathematical Olympiad, receiving a perfect score of 42,[5] one of the youngest to ever do so. He went on to Columbia University, where he won the Putnam competition at the age of sixteen years and four months, making him one of the youngest Putnam Fellows in history.[6] He was a Putnam Fellow two more times during his undergraduate years.[7] He earned his Ph.D. in 1987 under the supervision of Benedict Gross and Barry Mazur at Harvard University.[8]

From 1987 to 1990 he was a junior fellow of the Harvard Society of Fellows.[9]

## Work in mathematics

In 1987, he proved that an elliptic curve over the rational numbers is supersingular at infinitely many primes. In 1988, he found a counterexample to Euler's sum of powers conjecture for fourth powers.[10] His work on these and other problems won him recognition and a position as an associate professor at Harvard in 1990.[3] In 1993, he was made a full, tenured professor at the age of 26. This made him the youngest full professor in the history of Harvard.[11] Along with A. O. L. Atkin he extended Schoof's algorithm to create the Schoof–Elkies–Atkin algorithm.

Elkies also studies the connections between music and mathematics; he is on the advisory board of the *Journal of Mathematics and Music*.[12] He has discovered many new patterns in Conway's Game of Life[13] and has studied the mathematics of still life patterns in that cellular automaton rule.[14] Elkies is an associate of Harvard's Lowell House.[15]

## Music

Elkies is a bass-baritone and plays the piano for the Harvard Glee Club. Jameson N. Marvin, former director of the Glee Club, compared him to "a Bach or a Mozart," citing "[h]is gifted musicality, superior musicianship and sight-reading ability."[16]

## Chess

Elkies is a composer and solver of chess problems (winning the 1996 World Chess Solving Championship).[11] One of his problems is used by the famed chess trainer Mark Dvoretsky in his book "Dvoretsky's Endgame Manual".[17] He holds the title of National Master from the United States Chess Federation, but he no longer plays competitively.[18]

## Awards and honors

In 1994 he was an invited speaker at the International Congress of Mathematicians in Zurich.[19] In 2004 he received a Lester R. Ford Award[20] and the Levi L. Conant Prize.[21] In 2017 he was elected to the National Academy of Sciences.[22]
