Clarence was an invaluable help with my creation of a History of the University of Texas Physics Department web site. His memory of his time there in the late 1940s was amazing. He identified many people in an important picture from that time. He was alway willing to share his knowledge and stories. I will miss my conversations with this brilliant and kind man. In the photo added Clarence is 4th from left back row, 1946, UT Physics.
