Huber Coal Breaker

Ashley, Luzerne County, Pennsylvania

Marker Inscription

Erected by the Glen Alden Coal Co. in 1939, the breaker could process 7,000 tons of anthracite daily. It was among the first in the industry to utilize Menzies cones to separate coal from rock. An innovative aerial tramway disposed of waste by-products. Anthracite was sprayed with an iridescent chemical, to create Glen Alden's distinctive "Blue Coal." Operations ceased in 1976, following the decline of anthracite mining. It was demolished in 2014.

The Story

Rising over the anthracite fields of Luzerne County, the Huber Coal Breaker was built by the Glen Alden Coal Company in 1939 to crush, sort, and clean up to 7,000 tons of hard coal a day. It was among the first to use Menzies cones to separate coal from rock and an aerial tramway to haul off waste, and its product was famously dyed to market Glen Alden's trademarked "Blue Coal." When anthracite demand faded, the breaker shut down in 1976 and was demolished in 2014, closing a chapter in the region that once heated much of the nation.

Why it matters

The breaker embodies the anthracite era that powered American homes and industry and built the hard-coal communities of northeastern Pennsylvania.

Amedeo Obici (1877-1947)

Wilkes-Barre, PA · est. 2007

Amedeo Obici arrived in America at twelve, an Italian immigrant with no English, and worked a fruit-store counter before rolling out his own peanut cart on the streets of Wilkes-Barre. In 1906 he and fellow immigrant Mario Peruzzi founded the Planters Peanut Company, and Obici's knack for new roasting and processing methods turned a humble snack into a national brand. Planters' monocled Mr. Peanut became one of the most recognized trademarks in the country, and the company ran its headquarters from Wilkes-Barre from 1925 to 1961.

Jesse Fell (1751-1830)

Wilkes-Barre, PA · est. 1997

In 1808, tavern-keeper and judge Jesse Fell managed something others had struggled with: he burned hard anthracite "stone coal" successfully in an open grate, proving it could heat a home without a forced draft. Word of his simple experiment spread quickly, helping ignite the anthracite industry that would transform the Wyoming Valley into a coal powerhouse. Fell was also a civic leader, serving as a judge and as Wilkes-Barre's first burgess.

Wilkes-Barre, PA · est. 2004

Fred Morgan Kirby opened his first five-and-ten-cent store in Wilkes-Barre in 1884, helping pioneer the fixed-low-price retailing that transformed how Americans shopped. By 1912 he had built a chain of 96 stores, which he merged into F. W. Woolworth to help form one of the world's great retail empires. A committed philanthropist, he directed major gifts to higher education—including the study of civil rights—and to public health and recreation across northeastern Pennsylvania.

Wilkes-Barre, PA · est. 2000

From his base in Wilkes-Barre, Lyman H. Howe ran six touring companies that carried the new marvel of motion pictures to small towns and rural audiences across America. Billing his programs as "high class," he paired films with coordinated sound effects and captured world and local events alike—including President Theodore Roosevelt's 1905 visit to the city. For many Americans, a Howe show was their very first movie.
