WILLIAM ZOELLER DIES FROM DISEASE
The casualty list of yesterday contained the name of Private William Zoeller, of this city, who died of disease in France. Investigation disclosed that the young man, who was drafted from this city last May, was thirty-one years of age and was the son of Mrs. Frederick Zipperer, of 33 Lincoln Avenue, and that he died on December 22 of typhoid fever, according to the telegram received from Washington. The young man in his last letters spoke of having been slightly wounded, although how or where he did not mention when it was that he was wounded. He was a member of the 318th Infantry, having been assigned to that regiment when he was sent to Camp Upton with a number of other drafted men from this city last May. He was sent overseas in time to take part in a number of the closing battles of the war, and, in fact, fought almost continuously during the last six months of the war. He had previous military experience, having served two years in the German Army before he came to America.
Private Zoeller is buried at St. Mihiel American Cemetery, Le Cimetière Américain, 54470 Thiaucourt-Regniéville, France; Plot B, Row 2, Grave 13. Photo provided by Marie-Lou Meyer-Vinot, Associate, Saint-Mihiel American Cemetery.
