In Memoriam: Olli S. Miettinen (1936-2021)

Olli Miettinen was a native of Finland, but he spent his academic life in North American institutions: University of Minnesota, Harvard University and McGill University. Still, he kept a longstanding and intensive relationship with European universities, in particular through very influential courses he taught in Scandinavia and The Netherlands. This In Memoriam remembers both the European and the North American impact of Miettinen, by two of his close colleagues.
