The area was a part of the
Waldo Patent purchased by Moses Brown and Major Josiah Hill of
Newburyport,
Massachusetts, who initiated its settlement. In 1806, they built a
dam and
watermills on the
Pleasant River. First known as township T5 R8 NWP, the community was organized in 1819 as Brownville Plantation. It was named for Francis Brown (nephew of Moses Brown), who was a mill owner and trader from
Newbury, Massachusetts. In 1824, the town was incorporated as Brownville. Early settlers were given to clear and cultivate. Farms produced
hay,
oats,
potatoes,
wheat and garden
vegetables.
Water power from the Pleasant River attracted industry, including
sawmills,
clapboard mills,
gristmills, a shovel handle factory and a
carriage factory.
Quarries were established to extract the region's abundant
slate, the quality of which won first prize at the 1876
Centennial Exposition. In 1843, the Bangor & Piscataquis Slate Company opened with 60 employees. It sent out 8,000-12,000 squares of roofing slate annually. The Merrill Quarry opened in 1846 with approximately 80 employees, producing 30,000 squares of roofing slate annually. The Highland Quarry opened with
Welsh employees, recruited because they were accustomed to working in slate. The last quarry closed in 1917.
Iron ore was discovered at the foot of Ore Mountain. The
Katahdin Iron Works was established in 1843, when roads were cut out and a
blast furnace erected. A hotel and several houses were built for workers.
Charcoal was made in 14
kilns, consuming 10,000
cords of wood per year. The company and land were sold in 1845, and the new owners operated it until 1856, the year it produced 2350 tons of iron. However, shipping it to
Bangor was expensive. The
Bangor and Katahdin Iron Works Railway (B&KIW) was constructed to Brownville in 1881, then connected north to the Katahdin Iron Works in 1883. In 1889 the
International Railway of Maine was constructed by its owner
Canadian Pacific Railway (CPR), extending the CPR's transcontinental mainline east from
Montreal,
Quebec to
Saint John, New Brunswick. The CPR line passed three miles north of Brownville, where it crossed the B&KIW at a location that was named
Brownville Junction. In 1891, the B&KIW merged into the
Bangor and Aroostook Railroad (BAR) after the Katahdin Iron Works closed the previous year. The BAR line as well as the CPR line west of Brownville became part of the
Montreal, Maine and Atlantic Railway and are now part of the
Central Maine and Québec Railway. In 2019, the
Canadian Pacific Railway purchased the
Central Maine and Québec Railway, once again, giving the railway access to the
Port of Saint John running trains from
Brownville Junction to
New Brunswick via
New Brunswick Southern Railway. Local historian Bill Sawtell has documented many facets of the history of Brownville as well as the surrounding area. He has published numerous books with subjects such as Katahdin Iron Works, the Highland Quarry, the Bangor and Aroostook Railroad, and
Penquis Valley High School basketball. File:Herrick House & Street Scene, Brownville, ME.jpg|Street scene in 1910 File:Congregational Church, Brownville, ME.jpg|Community Church File:View at Brownville, ME.jpg|
