This collection, were originally included in the Pictorial Collections Hagley File reference prints as N60 (Nyalite) and P80 (Pulp Keg Mill), consists of photographs that document two separate activities. The first grouping shows an outdoor safety demonstration of Nyalite, a new explosive developed at the DuPont Experimental Station. This demonstration was probably conducted in the Hagley powder yards. Nyalite, an nitrostarch explosive compound developed in 1905, was designed for use in coal mines, and was marketed as a safer alternative to other mining explosives. The second group documents the pulp keg mill near Squirrel Run which, after the powder yards closed, was used for record storage by the DuPont Company. Currently, it is a Hagley Museum and Library property, the Hall of Records. Photographs show exterior and interior views.

The research reports also include scholarly articles which utilize Hagley’s collections as source material or address subjects pertaining to Hagley's mission. This collection has not been digitized in its entirety.

This collection was purchased in 1971 as part of a lot that included a number of other small collections. The photographer is unknown. The collection consists of thirty-five glass negatives and one original box. The negatives themselves include no identifying information, but a sticker on the box indicates that the images are of Fairmount Park in Philadelphia, Pennsylvania. Many of the images include identifiable landmarks. Most of the photographs appear to have been taken in Wissahickon Valley Park, historically part of the Fairmount Park system, prior to a 2010 merger of the city’s Fairmount Park Commission and the Department of Recreation. This park is located in Northwest Philadelphia, and includes Wissahickon Creek from its confluence with the Schuylkill River, and extends to the northwestern boundary of the city with eastern Montgomery County. While the photographs are undated, it is estimated that they were taken no earlier than 1908, based on the presence of what appears to be Walnut Lane Bridge, completed in October of that year, in one of the images.

This digital collection includes examples of these publications from the Hagley Library's collection. While the majority of these examples were published after the year 2000, they include publications from the the 1970s through the 1980s.

The Fitz Water Wheel Company specialized in the manufacture of water wheels and small power plants. John Fitz (1847-1914), who succeeded his father as head of the firm, developed the modern steel overshot water wheel. Fitz aimed its product at farmers, small millers, and small town hydroelectric and pumping stations in the United States and abroad. The spread of rural electrification cut into Fitz's market, but John Samuel Fitz, who had succeeded his father in 1914, kept the firm in business by shifting to production for "show" rather than productive use. The firm made many model wheels and turbines for engineering schools and historic restorations of working mills.

The oral histories presented here document the research and development processes that transformed Kevlar from a novel polymer in the laboratory to a life-changing product in the marketplace. Through many surprising twists and turns, the people profiled here managed to make Kevlar serve the complicated and occasionally contradictory interests of the DuPont company, scientific inquiry, the marketplace, and the general public. Their stories are a rich study in the business and technology of innovation. Interviews were conducted by John Kenly Smith, PhD, in 2014 and 2015.

The photographs are believed to have been taken by James Zellner (1836-1897), a local photographer, during the 1870s and 1880s. The majority of the images show scenes from Mauch Chunk (now Jim Thorpe) and the surrounding area, the Mauch Chunk Switchback Railway, and the waterfalls at Glen Onoko. Mauch Chunk was founded in 1818 to serve as a railroad and coal-shipping center to move coal mined by the Lehigh Coal & Navigation Company to markets along the east coast. Much of the coal that reached Mauch Chunk was transported via the Mauch Chunk Switchback Railway, which is also well-represented in this collection. The photographs in this collection document the railway’s use as a tourist attraction and passenger railroad, a secondary use that began in 1861 and became the railway’s primary function after the construction of an 1872 railway tunnel rerouted coal lines.
Joe Weisbecker was an engineer at RCA who invented an 8-bit microcomputer architecture that would serve as the foundation of RCA’s future microprocessor business. Weisbecker was well versed in programming languages, and during the 1970s contributed to the development of RCA’s programmable video game and educational systems: FRED, STUDIO II, STUDIO III, and STUDIO IV, and Microtutor. In addition to his work at RCA, Weisbecker ran his own business, Komputer Pastimes, which provided another outlet for his creativity. With it, Weisbecker developed simple games based on computer language for children and adults, wrote children’s books, and designed toys and greeting cards. This collection comprises digital files extracted from cassette tapes found in Weisbecker's collection as well as select paper documents related to RCA's video game systems and Weisbecker's work with Komputer Pastimes. The video clips of gameplay were provided by Kevin Bunch using an emulator developed and maintained by Marcel van Tongeren.
