Jorma Johannes Rissanen (October 20, 1932 – May 9, 2020)

lossless data compression. His work inspired the development of the theory of stochastic chains with memory of variable length.[3][2]

Education and career

Rissanen was born in Pielisjärvi (now Lieksa) in Finland and grew up in Kemi, a border town between Finland and Sweden. He moved to Helsinki and studied at the Helsinki University of Technology, where he obtained his Master’s degree in electrical engineering in 1956 and licentiate in control theory in 1960. He studied there under Olli Lokki and Hans Blomberg.[2]

Rissanen became an

universal coding/modeling. After retirement from IBM, he remained professor emeritus of Tampere University of Technology and a fellow of Helsinki Institute for Information Technology
.

Awards and recognitions

He was awarded the

IEEE Information Theory Society in 1998,[6] the Kolmogorov Medal of the University of London in 2006,[7] and the IEEE Claude E. Shannon Award in 2009.[8] A Festschrift collection, which includes an interview and substantial biographical information, was published by the Tampere University of Technology in honor of his 75th birthday.[1]

Personal life

Rissanen married Riitta Aberg in 1956, and they have a son Juhani and a daughter Natasha.[1]
