What it is
The John B. Tytus House is a historic house at 300 South Main Street in Middletown, Ohio, United States. Built in 1865, it was the home of John Butler Tytus (1875–1944), who invented a practical hot wide-strip continuous steel-rolling process that transformed the American steelmaking industry. The house was designated a National Historic Landmark in 1976 due to the efforts of Jeri and Pat Rossi, who bought the house in 1970. The house was the residence of the Rossi family until 2011.
