Dr. E.G. D. Cohen’s parents: David Ezechiel Cohen and Sophia Louisa de Sterke, circa 1920s.
100 years ago, on January 16th, 1923, Ezechiel Godert David “Eddie” Cohen, the Professor Emeritus at The Rockefeller University and leader in statistical physics and non equilibrium statistical mechanics, was born in Amsterdam, the Netherlands, into a Jewish family. His father, David Ezechiel Cohen, studied medicine in Amsterdam and after receiving his Ph.D. in 1913, specialized in dermatology. In 1921 he married the history teacher Sophia Louisa de Sterke. They had two children: Ezechiel Godert David “Eddie” and his brother, Carel Lodewijk David Cohen (now de Sterke), born in 1924. In 1942, during the German occupation of the Netherlands, the family was forced to go into hiding and was separated; Eddie and his brother escaped the fate of their parents, who were betrayed and perished in Auschwitz in 1943.
