The following is quoted from Thomas Murphy's 1928 History of Lackawanna County . 1 (Remember that references to now or today refer to 1928 and do not necessarily reflect life in 2003.)
Moosic Borough, like Old Forge and Taylor, was carved out of Lackawanna Township, which in turn was formed from protions of Pittston and Providence Townships in 1839. Moosic was so called from the mountains roundabout. The plentifulness of moose gave the name to the mountain. Dr Joseph Sprague, pioneer physician in the valley, was the first settler, locating on the present Main Street in 1771. He was driven out by the Penamites in 1884.
Moosic abuts on Luzerne County on the south. Its importance as a settlement began with the establishment of a powder plant along..... p486 p487... station stands. Squire Ehret, of West Pittston, was the first station agent. The Lehigh and Susquehanna changed the name of the village from Marathon to Spring Brook. The company piped water for its engines from Spring Brook at Spike Island to the station. In 1866 the Pennsylvania Coal Company began operation at "Starks Colliery." The "Stark Estate" sold building lots and many people built homes. The Pennsylvania erected 50 houses for their employees in what is now known as Stark's.
The Lackawanna River, Ascension Creek and the Spring Brook Creek flow through Moosic. The Spring Brook Water Company supplies water to the Lackawanna and much of the Wyoming Valley. The company maintains offices at Moosic. Its principal resevoirs are in Spring Brook Township.
About 1870 the name of the village was changed from Spring Brook to Moosic, we are told, to avoid confusion with the Spring Brook corners post office. At that time the post office was located in the general store of Edward Houser (first postmaster of the town), on the site of the present Moosic Hotel. The Lafflin, Boies and Twick Powder Company was absorbed in 1869 by the Moosic Powder Company whose mills were at Jermyn. Perhaps the change of name of the powder company had something to do wiht the change of the town name. Moosic was incorporated as a borough in 1899 and was divided into four wards. The first officers of the borough were: Burgess, Emmett Broadhead; Councilmen, Thomas Hailstone, W S Hutchings, William Dick, M T Garvey, John M Robertson, Richard Grimes, Christopher Fassold and Thomas Luttliffe; Secretary, John Hailstone; Justices of the Peace, P H Salmon, C W Thompson and James Ward.
Moosic at present has five churches, five school buildings, a borough building and two fire companies. The Langcliffe Church was built in 1880 by the Powder company. Moosic is tapped by two steam -- the D & H and the Erie -- and by the Laurel Line, a third rail system. Rocky Glen, an amusement park, established some 20 years ago is within the borough limits. The Minooka-Pittston state highway also traverses the borough. The Moosic and Greenwood hose companies afford fire protection. The Moosic Hotel was opened in 1878.
