Montgomery County History

Created on September 10, 1784 from part of Philadelphia County. Named perhaps for Montgomeryshire in Wales, for the Revolutionary hero Gen. Richard Montgomery, or for two legislators named Montgomery who advanced the bill to create the county. Norristown, the county seat, was laid out in 1784 and incorporated as a borough on March 31, 1812. It was named for Isaac Norris who owned land there.

Settled since 1685, the first residents were Germans, mainly pietists, in Germantown. Welsh, Scotch-Irish, English (mostly Quakers), and Swedes flocked to the area. The opening of the Schuylkill Canal in 1825 boosted the economy, followed by railroads. The Pennsylvania Railroad's Main Line passed through in the 1860s, giving rise to an elite residential area, "the Main Line." Intelligent farming has always been practiced on the county's good soil. Iron works arose in Norristown, Pottstown, and Conshohocken, and leather tanning was very important until the 1930s. Bernard McCready began a large textile factory in Norristown in 1826, with an enormous factory. Cigars, carriages, and paper were nineteenth-century Montgomery specialties, and marble is still quarried. From about 1900 to the 1970s steel, machinery, textiles, rubber, electrical, chemicals, and paint manufacturing were strong. The county is still a manufacturing giant. In 1992 it had the highest "value added from manufactures" figure of any Pennsylvania county. This was an amazing 9 ΒΌ billion dollars- more than double the figure for any other county. In addition, much personal income comes in from residents who work in Philadelphia. The county has the highest personal income rate and lowest percentage in poverty of the sixty-seven counties. Eighteen percent of the land is still farmed, and the county ranks eleventh in cash receipts from field crops. Both Republican Gov. Hartranft and Democratic presidential candidate Winfield Scott Hancock were natives.
