Jorma Rissanen

Jorma J. Rissanen (born 1932 in Finland) is an information theorist, known for inventing the arithmetic coding technique of lossless data compression, and the minimum description length principle.

An IBM researcher since 1960, Rissanen received his Ph.D. from the Helsinki University of Technology in 1965. Retired from IBM, he is now professor emeritus of Tampere University of Technology, and a fellow of Helsinki Institute for Information Technology. He was awarded the IEEE Richard W. Hamming Medal in 1993, the [http://www.kolmogorov.clrc.rhul.ac.uk/ Kolmogorov Medal] in 2006, and will be presented the IEEE Claude E. Shannon Award in 2009. A [http://www.cs.tut.fi/~tabus/TICSP_38_17.4.%2008.pdf Festschrift] collection was recently published to honor his 75th birthday.
