Note: With the foundation of the Dutch Institute for Food (in the beginning of the 1920's), prof. dr. E.C. van Leersum (Utrecht 1862 - Leersum 1938) began doing scientific food research. Van Leersum made plans for a workshop/laboratory of the Institute. After problems, that even resulted in Van Leersum having to bring his test animals to his own home in Amsterdam, he received room in the laboratory for Hygiene of the Amsterdam University in 1929, housed in the B.C.P. Jansen Institute at the J.D. Meijer square in Amsterdam. The main work of Van Leersum is his research on vitamins and his research on the chemical structure of food.
