Facts & Science

Held in Philadelphia from May 10 through October 10, the 1876 Centennial Exhibition celebrated the 100th anniversary of American independence.

Philadelphia hosted 37 nations in five main buildings and 250 additional structures on 285 acres of land. The celebration looked backward to commemorate the progress made over the 100-year period, and it announced to the world that American invention and innovation was on a par with that of our foreign counterparts. Patriotism abounded, as did messages of industrial and commercial prowess that promised a brighter future for all. Over nine million people attended this awesome consumer spectacle, an event that set the tone for a long series of world's fairs yet to come.

Four distinct anthracite coal fields encompass an area of 1,700 square miles in the northeastern portion of Pennsylvania. Early Coal Mining in the Anthracite Region is a journey into a world that was once very familiar.

In the late nineteenth and early twentieth centuries, underground coal mining was at its zenith and the work of miners was more grueling and dangerous than it is today. Faces blackened by coal and helmet lamps lit by fire are no longer parts of the everyday lives of miners in the region. These vintage photographs of collieries, breakers, miners, drivers, and breaker boys illuminate the dark of the anthracite mines. The pictures of miners, roof falls, mules, and equipment deep underground tell the story of the hard lives lived around the hard coal. Above ground, breaker boys toiled in unbearable conditions inside the noisy, vibrating, soot-filled monsters known as coal breakers.

Through original journal and newspaper accounts, J. Stuart Richards's Death in the Mines revisits Pennsylvania's most notorious mining accidents and rescue attempts from 1869 to 1943.

Since 1870, mining disasters have claimed the lives of over 30,000 men and boys who toiled underground in the anthracite mines of Pennsylvania. Sometimes they survived; many times they did not. The constant threat of fire, explosion, collapsed rock and deadly gas brought miners face to face with death on a daily basis. Through original journal and newspaper accounts, J. Stuart Richards's Death in the Mines revisits Pennsylvania's most notorious mining accidents and rescue attempts from 1869 to 1943. From the fire at Avondale Colliery that resulted in the first law for regulation and inspection of mines, to the gas explosion at Lytle Mine in Primrose that killed fourteen men, Richards reveals multiple facets of Pennsylvania's most perilous profession. Richards, whose family has worked in the mines since 1870, offers a startling yet sensitive tribute to an industry and occupation that is often overlooked and underappreciated

Pittsburgh's Bridges takes a comprehensive look at the design, construction, and, sometimes, demolition of the bridges that shaped Pittsburgh, ranging from the covered bridges of yesterday to those that  define the skyline today.

Pittsburgh is the City of Bridges, and what remarkable bridges they are! The area's challenging topography of deep ravines and mighty rivers - the Monongahela, Allegheny, and Ohio - set the stage for engineers, architects, and contractors to conquer the terrain with a variety of distinctive spans. Many were designed to be beautiful as well as functional. While other cities may have one signature bridge, Pittsburgh has such a wide variety that no single bridge can represent it.

For nearly 80 years, Pennhurst State School and Hospital was a reminder of how society viewed and treated people with intellectual disabilities.

Over its existence, Pennhurst was home to more than 10,600 people. Many spent decades there, working to keep the institution running by performing various jobs. While some enjoyed the lives they had fashioned for themselves at Pennhurst, for many others, life there was crushing. Pennhurst also played a central role in the lives of its employees and in the rural Pennsylvania community where it was located. Controversy plagued the institution for its entire existence, and it is remembered primarily as a place where bad things happened. However, it was much more than that. This book provides a window into that separate world, reminding those who were part of it of what they saw and did there and giving those who know only what they have heard or seen a different picture of what Pennhurst truly was.

Pennsylvania Hospital became America's first voluntary hospital, opening its doors on the eve of the American Revolution no less.

On the eve of the American Revolution, Pennsylvania Hospital opened its doors as a provincial charity for the physically and mentally ill. In a matter of decades, it became not only America's first voluntary hospital, but also the home of the first apothecary, medical library and surgical amphitheatre. From its radical conception by a group of extraordinary colonists, the hospital has evolved into a world-renowned facility that treats over 225,000 patients a year. In A History of the Pennsylvania Hospital, Kristen Graham introduces the people and ideas that guided the Pennsylvania Hospital through numerous wars and social and economic crises, landing it at the forefront of healing, learning and innovation.

Lost Coal Country of Northeastern Pennsylvania documents the region's disappearing anthracite history, which shaped the legacy of the United States of America and the industrial revolution.

The coal mines, breakers, coal miners' homes, and railroads have all steadily disappeared. With only one coal breaker left in the entire state, it was time to record what would soon be lost. Unfortunately, one piece of history that persists is underground fires that ravage communities like Centralia. Blazing for over 50 years, the flames of Centralia will not be doused anytime soon. Images featured in the book include the St. Nicholas coal breaker, Huber coal breaker, Steamtown National Historic Site, Lackawanna Coal Mine Tour, Eckley Miners' Village, Centralia, and the Knox Mine disaster. A hybrid history book and travel guide, Lost Coal Country of Northeastern Pennsylvania is one final recounting of what is gone and what still remains.

Guardian Dams. Today, most people remember Johnstown for a cataclysmic flood, but the city was also once known for steel.

From the early 1900s through much of the 1970s, millions of gallons of water per day were necessary to keep the city’s main industry alive. This is the story of the dams that didn’t fail, safely keeping the people of Johnstown and its steel industry prosperous for decades. It is also the story of transformation, for the dams built by an extinct steel company still stand and now safeguard areas of great natural resources and ecological importance in the highlands of Northern Appalachia. Surveying more than a century of wars, labor strife and economic catastrophe, author Joshua Penrod interweaves the story of these dams with the history of Johnstown itself.

From the author of Clean Time comes a firsthand account of the organizing effort inside one of the world's largest tech companies and its impact on one Pittsburgh family.In 2019, Ben Gwin played an integral role in organizing the contract workers at Google's Pittsburgh offices.
