Herminie (pronounced hurr-many) is named for Herminie Berwind, whose husband, Charles Berwind, was President of the Ocean Coal Company. The first mine at Herminie, known as the "Ocean No. 1 Mine," was opened in 1893 by Berwind-White Coal Company, of which Ocean Coal Company was a subsidiary. Fifty double houses were built for miners, plus five single-family houses for managers on Church Street. By 1900, the mine employed 271 people.
