Hendrik Willem Lenstra Jr. (born 16 April 1949, Zaandam) is a Dutch mathematician.


Lenstra received his doctorate from the University of Amsterdam in 1977 and became a professor there in 1978. In 1987 he was appointed to the faculty of the University of California, Berkeley; starting in 1998, he divided his time between Berkeley and the University of Leiden, until 2003, when he retired from Berkeley to take a full-time position at Leiden.

Lenstra has worked principally in computational number theory and is well known as the discoverer of the elliptic curve factorization method and a co-discoverer of the Lenstra–Lenstra–Lovász lattice basis reduction algorithm.

Three of his brothers, Arjen Lenstra, Andries Lenstra, and Jan Karel Lenstra, are also mathematicians. Jan Karel Lenstra is the former director of the Netherlands Centrum Wiskunde & Informatica (CWI). Hendrik Lenstra was the Chairman of the Program Committee of the International Congress of Mathematicians in 2010.[1]

Awards and honors[edit]

In 1984 Lenstra became member of the Royal Netherlands Academy of Arts and Sciences.[2] He won the Fulkerson Prize in 1985 for his research using the geometry of numbers to solve integer programs with few variables in time polynomial in the number of constraints.[3] He was awarded the Spinoza Prize in 1998, and on 24 April 2009 he was made a Knight of the Order of the Netherlands Lion. In 2012 he became a fellow of the American Mathematical Society.[4]
