When in 1975 the University of Utrecht founded the Kramers Chair for Theoretical Physics we were fortunate to find Professor Eugene P. Wigner (1902-1995) from the University at Princeton willing to accept the first invitation. His appointment was from Sept. 1, 1975 to Dec. 1, 1975, but due to his wife's health problem he could be present for only a part of this period. He arrived on October 6 and gave an inaugural lecture on the work of Kramers (October 13, 1975). Then he started a lecture course on the General Principles in Physics, in particular of course Symmetry Principles.
He was amazingly active and generously contributed to the scientific life at the Institute for Theoretical Physics. Numerous were the discussions on various aspects of physics and on the subjects that the members of the Institute were concerned with. He made a lasting impression on those who were there at the time. In addition he was invited for a number of talks at other universities in Holland and elsewhere. He even met with several authorities on the subject of Civil Defense. His impressive knowledge and unassuming personality are remembered by all those who were present at the time.
