Both men served with the United States Air Corps in WWII following the bombing of Pearl Harbor, and Sheldon G knew both Franklin D Roosevelt and Harry S Truman. The men heavily influenced the development and growth of the asphalt and concrete industries in the United States, giving input into the construction of the interstate highway system.
