Olaf A. Hougen was one of the founders of the modern chemical engineering profession. He had a keen sense of responsibility, and believed that leading research departments have an obligation to the profession and to society to work actively to strengthen the crucial link between the generation and dissemination of new knowledge. In this spirit, the following programs are intended to honor Professor Hougen. They are made possible through the outstanding generosity of the alumni and friends of the department who have contributed over many years to the endowed Hougen Professorship Fund through the University of Wisconsin Foundation.
