He served the Penn Wynne community as a member and ultimately deputy chief of the Penn Wynne Fire Company, and as a member and choir member of Penn Wynne Presbyterian Church for 58 years.
"He was singing hymns up until the time he died," said his wife, Sophia Landherr Beltz.
He also served his country during World War II, in the Army and, later, as a special operations recruit for the Office of Strategic Services (OSS), a U.S. intelligence agency formed during the war. His assignments, all classified, were in Africa, Italy, France, and Germany from 1942 to 1945.
He told his wife that he was a radioman, but made no other mention of what he did, she said.
In the fall of 2012, Mr. Beltz was among 13 World War II veterans singled out by France for the honor of Knight of the Legion of Honor. The medallion he received recognized his contributions to the liberation of France.
French Veterans Affairs Minister Kader Arif presided over the September ceremony in Normandy.
Mr. Beltz lived in Wynnewood his entire adult life.
Besides his son, and wife of 68 years, Mr. Beltz is survived by a daughter, Ginger Dietz; four grandchildren; four great-grandchildren; two sisters; and many nieces and nephews.
