Gerrit "Ger" Challa (born 18 December 1928)[1] is a Dutch chemist. He was professor of chemistry and polymer technology at the University of Groningen from 1965 to 1993.[2]

Challa was born in Amsterdam.[1] He studied chemistry between 1946 and 1953. He worked ten years for the Institute of Cellulose Research of the Algemene Kunstzijde Unie [nl].[3] Challa obtained his title of doctor in maths and physics on 13 May 1959 under Jan Ketelaar at the University of Amsterdam. His thesis was titled: "Formation of polyethylene terephthalate by ester interchange : equilibria kinetics and molecular weight distribution".[1] After starting as professor at the University of Groningen he set the possibility to study polymer chemistry.
