From July, 1944 to July, 1946 Bob served in the U.S. Army. He was a Staff Sergeant with the European-African-Middle Eastern Theater Ribbon and 3 Overseas Service Bars.

He was always known as Bob Roggerman but there is some confusion as to his full given name. The 1930 census gives his name as Lewis B. On his 1938 marriage license, he is listed as Lewis Ralph Roggerman. His 1940 military draft registration he is shown as Ralph Lewis Roggerman and that is how he signed the form himself. The 1950 census shows him as Ralph L. Roggerman. We will call him Ralph Lewis or Bob.
