Gijsbert de Leve

Gijsbert (Gijs) de Leve (15 August 1926 – 19 November 2009)[1] was a Dutch mathematician and operations researcher, known for his work on Markov decision process.[2] Gijs de Leve is considered the founder of operations research in the Netherlands.[3]

Biography

Born in Amsterdam De Leve received his MA in Mathematics and Physics in 1954 at the University of Amsterdam. There he also received his PhD cum laude in 1964 for the thesis Generalized Markovian decision processes, advised by Jan Hemelrijk and Johannes Runnenburg.[4]

De Leve was appointed Professor Operations research, in particular management scientific applications at the University of Amsterdam in 1972.[5] Among his doctorate students were Henk Tijms (1972), Alexander Rinnooy Kan (1976), Jan Karel Lenstra (1976), P. Weeda (1978), Awi Federgruen (1978), Antoon Kolen (1982), Roy Jonker (1986), Anton Volgenant (1987), Jeroen de Kort (1992), Erik H.J. van der Sluis (1993), Nanda Piersma (1993) and Cees Duin (1994).[4] He retired from the University of Amsterdam 1 September 1991.

In honor of De Leve in 1997 the Gijs de Leve prize is initiated for the best PhD thesis in the area of Mathematics of Operations.
