Penn students and alumni are bound together by the continuous observance of a number of student customs and traditions. Today the most notable is the annual Hey Day event which incorporates elements of many other traditions past and present. Hey Day, however, is just one of many student traditions which have evolved, merged, and sometimes disappeared from the Penn campus. The histories and images of some of these traditions are presented here.
