bio

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. He was awarded the Spinozapremie in 1998, and on 24 April 2009 he was made a Knight of the Order of the Netherlands Lion. 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 LLL algorithm. His three brothers Arjen Lenstra, Andries Lenstra and Jan Karel Lenstra are also mathematicians. Jan Karel Lenstra is the present 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.
