Live and act

Rissanen studied at the Helsinki University of Technology with a degree in engineering in 1956, a technical licentiate in 1960 and a doctorate in control theory and mathematics in 1965. From 1960 he researched at IBM Research in the department of information theory and mathematics. 1973/74 he was professor of control theory at Linköping University . After his time at IBM he was at the Helsinki Institute of Science and Technology and at Tampere University of Technology .

In 1978 he introduced Minimum Description Length and he was a pioneer in arithmetic coding in the late 1970s and early 1980s .

In 1993 he received the Richard W. Hamming Medal , in 1998 the Golden Jubilee Award for Technological Innovation from the IEEE Information Theory Society and in 2009 the Claude E. Shannon Award .
