Simon Plouffe

Simon Plouffe (born June 11, 1956, Saint-Jovite, Quebec) is a mathematician who discovered the formula for the BBP algorithm (the Bailey–Borwein–Plouffe formula) which permits the computation of the nth binary digit of π, in 1995.[1]

He co-authored The Encyclopedia of Integer Sequences, made into the web site (On-Line Encyclopedia of Integer Sequences) dedicated to integer sequences later in 1995. In 1975, Plouffe broke the world record for memorizing digits of pi by reciting 4096 digits, a record which stood until 1977.[2]

Plouffe discovered an algorithm[3] for the computation of π in any base in 1996.[4] His Inverter is a web site that contains 215 million mathematical constants as of June 3, 2012.[5]
