Manufacturer, Inventor. A native of Prussia, he was born at Ladbergen in Westphalia. Huenefeld emigrated to the United States and settled near Cincinnati, Ohio. Soon after the Civil War, he and his partner, John H. Schroer, went into business together importing and selling tin plates and related machinery. He established the Huenefeld Company in 1872 and manufactured several household items including ranges, ovens, heaters, furnaces, refrigerators, and washing machines. Huenefeld claimed a technological breakthrough in 1909 when he designed the first successful glass door oven. A wealthy businessman, he had several homes built on Walnut Hills near Cincinnati and resided in one of them until his death in 1931 when he was 92 years old. The Huenefeld Company was operated by his sons and continued until 1966. In 2003, the Ohio Historical Society placed a historical marker commemorating his glass oven door achievement at 2701 Spring Grove Avenue, the former site of his factory.
