The Pennsylvania Railroad Company. A history prepared by Coverdale and Colpitts
In preparation for its 1946 centennial, the Pennsylvania Railroad Company commissioned the engineering firm of Coverdale & Colpitts to prepare a comprehensive history of the company. The commission involved the creation of two products. The first was this detailed four-volume history of the PRR System as it existed in 1946 for the use of management only. The data collected was subsequently utilized to produce the second product, Centennial History of the Pennsylvania Railroad Company, which was mass distributed. The former work was printed in a limited edition of 100 copies which were strictly controlled and issued only to certain corporate officers, making it an essential but extremely rare source for PRR history. As its title indicates, this is not a narrative history, but rather a statistical compilation which accounts for the construction, financing and corporate succession of every segment of the PRR System to 1946. As very little mileage was added after that date, it practically covers the entire railroad. The volumes are arranged in the form of a chart of corporate succession, with the successor company followed by all of its predecessors in chronological order.
Incorporated in 1846, the Pennsylvania Railroad Company became the largest railroad in the United States in terms of corporate assets and traffic from the last quarter of the nineteenth century through the mid-twentieth century. This collection of more than 5200 negatives from the official Pennsylvania Railroad files largely depict PRR trains, tracks, equipment, and facilities. The collection also contains numerous views of similar facilities and equipment on other railroads, of nearby buildings and properties, or of standardized equipment and accessories that were collected by the PRR for reference. The negatives were digitized to positives for online access. Most of the digital images seen here are black-and-white, low resolution copies produced from the original negatives.

Pew Charitable Trusts is a major philanthropic organization based in Philadelphia, Pennsylvania. Now America's second largest private foundation, Pew has traditionally concentrated their resources in the Philadelphia region, assisting secondary schools, libraries, seminaries and hospitals.

In the 1980s, Pew launched two new programs, the Health Policy and the Biomedical Scholar Programs. These initiatives have funded important work in medical education, biochemistry, AIDS research, dentistry, and veterinary medicine. This digital collection represents a small selection of materials from their records in the Hagley Library's Manuscripts and Archives Department.

Pierre A. Gentieu (1842-1930) was a long-term employee of E.I. du Pont de Nemours & Company who created an invaluable photographic record of the company's Brandywine Mills at the turn of the century. He was born in southwestern France in 1842, and emigrated to the United States around 1859. Gentieu began work in the Hagley Powder Yard in June, 1877. In 1881, he was appointed yard clerk by Francis Gurney du Pont, who took Gentieu with him when he established the smokeless powder plant at Carney's Point, N.J. in 1890. Gentieu also developed an amateur interest in photography, and between 1889 and 1910 he produced several hundred views of the Hagley Yards and their immediate surroundings. He was serving as the company's chief storekeeper at his retirement in 1925. Gentieu's papers include correspondence with du Pont family members and coworkers, an account book of powder packed at the Hagley Yard (1858-1902); a record book with lists of explosions (1882-1909); time work sheets of powdermen during the 1890s; and a list of the principal events in the powder yards from 1882 to 1911. This document describes the work process to manufacture black powder at Hagley and several accidents that took place during this period.
The Plymouth Cordage Company of North Plymouth, Massachusetts, was founded in 1824 by Bourne Spooner (1790-1870), an ardent abolitionist whose commitment to free labor ideology led the company to implement generous employee benefits and facilities for its workers. By the late 19th century, the company had become a major international manufacturer of rope and twine. Its products were in heavy use within shipping and fishing industries, though its binder twine was also in widespread use on farms. After serving as the largest employer in Plymouth for over 100 years, the company went out of business in 1964. Its assets were purchased by the Columbian Rope Company in 1965. This album documents the company's operations in the years around 1900. It contains sixteen photographs of plant interiors showing machinery and manufacturing processes, and two exterior views of the building.

This digital collection of twenty-five pamphlets dating from 1936 to 1956 contains the Hagley Library’s holdings of the publications of the Public Affairs Committee.

Between 1936 and 1986, the Committee published over two hundred pamphlets on topics ranging from industrial policy, war and society, medical science, income distribution, consumer protection, economic policy, gender inequality, the social sciences, and more. While its approach to these topics sometimes led to accusations of socialist or un-American sympathies, its most controversial publications addressed race relations, particularly ‘The Races of Mankind’ (1946), which was banned from use in the U.S. Army for its rejection of biological theories about racial hierarchy.

Spruance. Over the decades, it continued to expand. By the 1950s and 1960s, it was producing cellophane as well as new products such as Tyvek, Nomex, and Teflon. During this time, Yourison was named the Spruance Plant's Power Consultant, largely spearheading an effort to reduce energy use through the evaluation of coal by utilization cost. His efforts led to the modernization of the plant's power facilities, resulting in an eventual savings of a half a million dollars a year. Yourison retired from the Dupont Company on March 31, 1963.

Reading Company file related to the Pinkerton Detective Agency
Reports and billings for Pinkerton detectives employed by Franklin B. Gowen, president of the Philadelphia & Reading Railroad, on three different missions. The first involved violence in the Anthracite Coal Region, 1873-1880. James McParlan was commissioned to infiltrate the alleged Molly Maguires, a secret Irish organization that practiced retributive murders and beatings against bosses and rival ethnic gangs. Two other agents were sent to collect information and infiltrate the miners’ union during the Long Strike of 1875, and Robert J. Linden was sent to organize a company police force to protect property and arrest suspects. Gowen also had Pinkertons shadow a committee of the state legislature investigating the Reading’s activities during the strike. Lastly, Gowen used Pinkertons to track lobbyists of the rival Pennsylvania Railroad and legislators suspected of receiving bribes to have the state assume the claims arising out of riot damage during the great 1877 railroad strike and to report on the progress of their trials in 1880. Note: This online collection includes the Molly Maguire materials in Hagley Library’s collection of Reading Company records (with the exception of 8 volumes of stenographic reports of trial proceedings for John Donohue, Patrick Hester, Martin Bergen, James McDonnell and Charles Sharpe).

Before the rise of phonographs and radio, publishers of sheet music dominated the American music industry. The biggest music publishing houses were those of ‘Tin Pan Alley’ in New York City. But throughout the United States, publishing houses, lyricists, arrangers, and composers, often working in partnership with local musical instrument stores, emerged to serve both national and regional consumers. As the American middle class grew during the mid-19th century, musical instruments and the ability to play them (and pianos in particular), became widespread signifiers of respectable middle-class status, and publishers responded to meet this emerging market. By the early 20th century, however, as phonographs became more commercially popular, sheet music was replaced by recorded music. This decline was further hastened by the public’s embrace of radio within the home in the years after 1920. The scores assembled here have been drawn from a variety of collections within the Hagley Library. New items may be added as they are scanned.
