E.I. du Pont de Nemours & Company is a chemical company more commonly referred to as the DuPont company, established in 1802. DuPont's Chestnut Run Laboratories was opened in 1954 near Wilmington, Delaware. This collection consists of two albums documenting the history of the Chestnut Run facility between 1954 and 1961. One album contains primarily photographs taken of the facilities exteriors between 1955 and 1958. The second album contains mostly newspaper clippings between 1954 and 1961.

The Foreign Relations Department of E.I. du Pont de Nemours & Company was first organized on August 1, 1930, for the purpose of improving the exchange of scientific and technical information with DuPont's British counterpart, Imperial Chemical Industries, Ltd. These materials consist of records of the International Finance Division within DuPont International, and more particularly the Division's Vital Records Program and Nylon de Mexico reorganization.

E.I. du Pont de Nemours & Company is a chemical company more commonly known as the DuPont Company. It was established in 1802 and began by manufacturing gunpowder, later moving into chemical compounds. During the 1920s and 1930s, under the leadership of Irénée du Pont (1876-1963), president from 1919 to 1926, and Lammot du Pont (1880-1952), president from 1926 to 1940, the company became the world's leading chemical manufacturer producing smokeless powder, dynamite, dyes, cellophane, textile fibers, and artificial rubber. The records primarily document the presidency of Lammot du Pont, with some fragmentary records from the Irénée du Pont period.

Jervis Langdon, Jr. (1905-2004) was a railroad executive largely known for rehabilitating ailing railroads and for his influence in the reshaping of national railroad policy in the 1970s. Langdon's papers document the U.S. railroad industry's efforts to obtain a competitive rate rule through Congress in relation to other freight carriers, such as trucks and barges. Also included is material covering Langdon's efforts in revitalizing bankrupt railroads, such as the Chicago, Rock Island and Pacific, and the Penn Central reorganization and its subsequent 1980 valuation case.

Secretary's files series is organized into two subseries: Contract file; Contract file analysis. This series consists of documents removed from the Secretary's Contract File because of supposed historical value. At some point after 1980, they became associated with the B.L. Aldridge file in Series II, but were not part of them.

The first subseries of original contracts and agreements pertain to the formation of RCA between 1919 and 1932. This includes prior rights acquired from the Marconi's Wireless Telegraph Company Limited , the construction of American transmission stations by the Marconi; world radio communication rights; the dissolution of the American Marconi company; disputes over the Marconi and Alexanderson alternator patents; the disputes among RCA, GE and Westinghouse; and the antitrust suit.

The second subseries, "Contract File Analysis," consists of copies of cover sheets from the Contract File giving the contract number, the name of the parties and an abstract of the action. The series appears to have been produced in 1929-1933 at the time of the antitrust suit, when RCA became an independent company for the purpose of determining which agreements should be assigned to which of the new RCA subsidiaries and which were no longer in force.. The sheets include most of the important contracts entered into by RCA or inherited from predecessors down to early 1933. The oldest contract is dated 1887.

The Special Court was created under the Regional Rail Reorganization Act of 1973 (signed January 2, 1974) for the purpose of adjudicating conflicting claims arising out of the act-mandated transfer of viable properties of six bankrupt railroad systems to a new government-funded entity to be called the Consolidated Rail Corporation (Conrail). The Special Court Reporter constitutes a step-by-step account of its proceedings and the playing out of the final stages of railroad reorganization in the Northeast, but it is heavily weighted towards procedural matters concerning what constitutes a fair valuation. It does not contain actual testimony or exhibits.
