Historical NotesThis respirator was used by Stephen Toth during his work as a coal miner. An immigrant from Budapest, Istvan (Stephen) Toth came to Western Pennsylvania at the turn of the 20th century in search of work. He found his first job at the coal mine at Leisenring but soon moved to Connellsville, where he found strong camaraderie among his fellow countrymen who were members of the local St. Emory's church. Toth soon obtained a job at Whitsett, a mining town several miles upriver from the Darr Mine.
