More than one of our alumnae have been clients of mine. This picture was given to me from one of the alumnae, when ADPi first returned to campus after WWII (the whole chapter closed to work on the war effort):
It's from 1946, and the woman who gave it to me is H. Davis, sitting almost at the middle.
FYI: Many of the sororities at Pitt had as few as six members prior to 1960. There may have been as many as 17-18 sororities, but even the largest sororities didn't have 30 members!
