My mother-in-law, Emmie Lucassen-Reijnders, who has died aged 87, was a scientist who made a distinguished contribution to the discipline of physical chemistry. Her work is still cited 60 years after publication, and she was a remarkable role model for women in science.
The younger daughter of schoolteachers, Piet Reijnders and Rens Remmers, Emmie was born in Vught in the Netherlands, and went to the local grammar school before studying chemistry at the University of Utrecht. She graduated in 1959, a year after meeting Jaap Lucassen, a fellow chemistry student, whom she married in 1961.
