I was a landscape architecture major and took one of Jack's classes; maybe it was 1979. Jack always had a pencil and a sketch pad handy in his pocket. His proficiency was remarkable. He would spot something interesting in the landscape, pull out the pencil and pad and sketch spontaneously. He had an affinity for the landscape and the ability to see things in it that were not apparent to me. He was truly an artist and made a big impression on me. My sympathies to Jack's family and friends.
