Eternal kitchen ranges with "eternametal" flues were the main feature of an advertising campaign by Engman-Matthews Range, a kitchen range company founded by Harry Engman Jr. in the early 20th century based in South Bend, Indiana. South Bend was a hub of kitchen range commerce during the early 20th century, beginning with The South Bend Range company, which was founded by Jacob Woolverton and William Kizer in 1898.
The South Bend Range company primarily sold coal and wood kitchen ranges, and one of their early partners was Harry Engman Jr., a son of a St. Louis stove manufacturer. Engman left the company not long after beginning a partnership with South Bend Range to establish his own stove manufacturing company, Engman-Matthews Range. Engman-Matthews Range marketed "eternametal" amalgamated copper and steel kitchen ranges that were supposed to outlast any wear and tear that might occur in the kitchen. While their competitor, South Bend Range Company, continued selling ranges late into the 20th century, Engman-Matthews Range did not last past the end of the 1920s.
