He worked on many Pittsburgh landmarks including the Fort Pitt Tunnel, Three Rivers Stadium and the U.S. Steel Building. Ron loved spending time with his family. As an avid Steelers fan, he enjoyed attending many games. He got as much pleasure planning trips all over the world as he did taking them. One of his favorite pastimes was his model trains. He spent countless hours setting up the trains in the family room for the holiday visits from friends and family. He was preceded in death by his parents, Ernest and Herta Witthohn; and his eldest son, Mark E. Witthohn. Ron is also survived by his sons, David W. Witthohn (Judy) of Golden, CO and Ronald L.
