On the way back they were enveloped by chill mists and her father caught a cold which later developed in pneumonia from which he died on April 1. Adelheid attended the University of Louvain and gained a doctorate in 1938.
During the Second World War she emigrated with most of her family to the United States to escape the Nazis.
