Prof. Dr. Onken passed away

Prof. Dr. Ulfert Onken, one of the initiators of the Dortmund Data Bank, passed away on April 22, 2021. In collaboration with Prof. Dr. Gmehling, the development of a computerized database for experimental phase equilibrium data was started in 1973 at the University of Dortmund. The Dortmund Data Bank became a success story that continues to this day. Amongst others, the Dortmund Data Bank has been used for the development of numerous thermodynamic models, and contributed to solving various problems in the area of process synthesis and design.

Our deepest sympathy goes to his relatives.
