Ambridge in Beaver County, Pennsylvania — The American Northeast (Mid-Atlantic)
Schools
The large, two-story Blaine House was dismantled and reassembled here some time after the June 1824 arrival of the Harmony Society at Economy. According to tradition, the building was used as one of the places for the first Harmonists in Economy to stay while they built the town. It was later used as a school, and eventually a warehouse. After the close of the Society in 1905 it served as a Presbyterian church for a short time and later as an apartment building with major renovations (circa 1930).
The Harmony Society built a new school in 1884. Many Harmonist hired workers' children attended this school. Prior to becoming trustees of the Harmony Society, John Duss (1860-1951) and his wife Susie Duss (1859-1946) taught school in this building. After the Society closed in 1905, the structure stood vacant until it was turned into an apartment building around 1930.
Constructed in 1904, the third school was the Economy Public School, also known as the Fourth Ward School of Ambridge. The building was designed by the first female architect in western Pennsylvania, Elise Mercur Wagner. It was razed in 1964.
