In 1900, the population was 2,567, much of it attracted by the prospects of finding work at a large anthracite coal site in the region. Coal mines, cut glass works, silk, powder, grist, planing, sawmills, bottling works, and fertilizer factories dotted the borough during the early years of the twentieth century.
By the time of the 2020 census, the population had declined to 2,156.[5]
Jermyn is presently the mailing address of the Lakeland School District. East Jermyn, the section of town east of the Lackawanna River and west of the small section of Archbald known as "Nebraska", is commonly referred to as "The Lane".
History
The borough originally named Gibsonburg, was named for John Jermyn, a businessperson in the mining industry.[6][7]
Jermyn is known as "The Birthplace of First Aid in America." In 1899, Dr. Matthew J. Shields conducted the nation's first training class on First Aid at the Windsor Hotel. He instructed 25 miners from the Jermyn Coal Colliery how to provide quick, effective medical care until a physician could reach the mine. After completion of the course, each of the miners was able to provide first aid to injured comrades—leading to dramatic reductions in serious mining injuries and fatalities. Unfortunately for numerous coal miners, a "silent killer" called black lung disease was caused by inhaling coal dust over time and this resulted in the untimely deaths of many former miners.
Jermyn was incorporated as a borough in 1870 and celebrated its centennial in 1970 throughout the year, with a week-long celebration in July. A carnival and a massive fireworks display was held in East Jermyn at the St Michaels Russian Orthodox Hall grounds. Makeshift jails were built throughout the town and located at several street intersections to accommodate persons that were inebriated from too much alcohol. "Drunk Tanks" if you will.
