To the family of Dr. Wayne Pettyjohn, I happened to search the web for Dr. Pettyjohn and sadly found out that he died this past May. I wish to extend my condolences to the Pettyjohn family. Dr. Pettyjohn was instrumental in my college major while he was at Ohio State. I always remember our time together because of Dr. Petthyjohn's directness but his fairness. He was most instrumental in guiding me as both a professor and someone who was well-rounded in his approach to life. Most folks who came to know Dr. Pettyjohn learned early he had a sarcastic wit and if you were overly sensitive, he could shock you a bit. After all the years since I was at Ohio State as a geology student (late 1960s to early 1970's ) I would always wonder what Dr. .Pettyjohn was doing. He surely was a most remarkable person who truly enriched my life.
