In Memoriam Prof. Dr. A.J. Kluyver 1888–1956

Many scientists, and especially the numerous friends he had among them, were deeply moved when on the 14th May it became known that in the early hours of that day professor Dr. A. J. Kluyver had suddenly passed away. Only two days before Kluyver had attended the annual meeting of the “Hollandsche Maatschappij der Wetenschappen” at Haarlem. At the social gathering after the meeting he had keenly taken part in the discussion of scientific problems with several of his friends. Nobody at that time could think that his end was so near at hand. Albert Jan Kluyver was born on the 3rd June 1888 at Breda. After his father had been appointed professor of mathematics at Leyden University, Kluyver followed the primary and secondary school in that town. From 1905-1910 he studied at the Technical University, Delft, where he graduated in chemical technology.
