About Landon Curt Noll
Born 1960. Landon Curt Noll is an American astronomer, mathematician, cryptographer and computer scientist, known for Fowler Noll Vo hash, International Obfuscated C Code Contest and Lavarand.
Landon Curt Noll (born October 28, 1960) is an American computer scientist, co-discoverer of the 25th Mersenne prime and discoverer of the 26th, which he found while still enrolled at Hayward High School and concurrently at California State University, Hayward.
Biography Noll was born in Walnut Creek, California, United States. At age 18, he became the youngest person to break the record for the largest known prime. He has held or co-held the record three times. He is also the co-inventor (with John Horton Conway) of a system for naming arbitrarily large powers of 10. He also helped start the International Obfuscated C Code Contest, and is a co-inventor of the Fowler Noll Vo hash function.
He was also a member of the Amdahl Six team (John S. Brown, Bodo Parady, Curt Landon Noll, Gene W. Smith, Joel F. Smith, and Sergio E. Zarantonello) which discovered another record prime in 1989; this prime remains unusual as a record large prime as it was not a Mersenne prime.
Noll is an amateur astronomer. His work includes measuring the Solar parallax during the 2004 Transit of Venus as well as the search for Vulcanoid asteroids.
He was also involved in politics as a Sunnyvale, California city council member and vice-mayor.
