History

The area where Norristown sits was originally owned by the family of Isaac Norris. Along with William Trent, Norris purchased the land on October 7, 1704, for 50¢ per acre. In 1712, Norris acquired Trent’s share and established a gristmill at the foot of present-day Water Street.

Named the county seat in 1784 when Montgomery County was formed, Norristown was incorporated as a borough in 1812 and subsequently enlarged in 1853. About 500 people lived there at the time of its incorporation. Growing rapidly after the Civil War, it swelled to 22,265 people by 1900. By 1940 it was home to 38,181 Norristonians, making it the most populous borough in Pennsylvania before declining in the decades after World War II, and in fact it was described in that year as “the most populous independent borough in the United States.”

At its height, Norristown was an industrial, retail, banking, and government center. Breweries, cigar factories, textile mills, icehouses, foundries, rolling mills, and lumber yards provided ample employment for skilled laborers and artisans. The downtown featured two department stores, several theaters, and enough goods and services that residents never had to leave town to find anything they needed. Although primarily settled by the English and a handful of Germans, Scots, Dutch, and Swedes, in the mid-1800s the Irish began arriving in large numbers, followed by waves of Italians at the turn of the century.

With the opening of new malls in nearby King of Prussia and Plymouth Meeting, the downtown declined in the decades after World War II. Industry soon followed, as many companies closed or relocated into new industrial parks throughout Montgomery County.
