Jacob Willem "Wim" Cohen (27 August 1923 Leeuwarden – 12 November 2000) was a Dutch mathematician, well known for over hundred scientific publications and several books in queueing theory.

Cohen was born in a Jewish family, as the son of Benjamin Cohen and Aaltje Klein.^[2] Having acquired an autodidact knowledge of mathematics while in hiding during World War II, Cohen got an Engineer's degree (1949) and Ph.D. degree (1955) in mechanical engineering at Delft University, on a dissertation titled Stress Calculations in Helicoidal Shells and Propeller Blades. He worked as teletraffic engineer with the Telecommunications group at Philips (1950–57), at the applied mathematics department at Delft (1957–73) and University of Utrecht (1973-1998). He was buried in Haifa.^[3][4]
