Dr. W. Kroll, a young posdoc working under Heisenberg at Leipzig in the 1930s, was forced to escape from the Nazis and eventually came to the National Taiwan University in 1941. He taught many of the advanced courses in theoretical physics for over two decades, and prepared a generation of physicists from Taiwan. A symposium on pure and applied physics was held in memory of Professor Kroll at the University of Massachusetts, Dartmouth, in August 1996. These proceedings, composed of papers contributed to the symposium by many of Professor Kroll's former students now reaching professorial ranks in the West, reflect in a small measure the legacy he left behind.
