Fabrice Bellard (French pronunciation: [faˈbʁis bɛˈlaʁ]) is a computer programmer who is best known as the creator of the FFmpeg and QEMU software projects. He has also developed a number of other programs, including the Tiny C Compiler.
He was born in 1972 in Grenoble, France and went to school in Lycée Joffre (Montpellier), where, at age 17, he created the famous executable compressor LZEXE. After studying at École Polytechnique, he went on to specialize at Télécom Paris in 1996.
Fabrice Bellard's entries won the International Obfuscated C Code Contest twice: In 2000, he won in the category "Most Specific Output" for a program that implemented the modular Fast Fourier Transform and used it to compute the then biggest known prime number, 2^6972593-1; and in 2001, he won in the category "Best Abuse of the Rules" for a tiny compiler (the source code being only 3KB in size) of a strict subset of the C language for i386 Linux. The program itself is written in this language subset, i.e. it is self-hosting.
Pi calculation record 
On December 31, 2009, he claimed the world record for calculations of π, having calculated it to nearly 2.7 trillion places in 90 days. Slashdot wrote: "While the improvement may seem small, it is an outstanding achievement because only a single desktop PC, costing less than $3,000, was used — instead of a multi-million dollar supercomputer as in the previous records." On August 2, 2010, this record was eclipsed by Shigeru Kondo who computed 5 trillion digits, although this was done using a server-class machine running dual Intel Xeons, equipped with 96GB of RAM.
