Francis Bannerman Son was a major purveyor of military goods to sportsmen and collectors in New York City over three generations. The collection consists of Bannerman family's personal papers, correspondence, travel diaries, and financial documents concerning Bannerman Island.

Charles Jennings (1916-2006) served for more than forty years as RCA Global Communications’ primary liaison in Japan, figuring prominently in the development of post-World War II Japanese communications systems. The collection consists primarily of black and white and color photographs, albums, advertising posters, papers, and unbound scrapbook boards of photographs and ephemera. The images predominantly relate to Jennings’ business and personal life during his time in Japan, addressing the themes of Japanese and trans-Pacific telecommunications activities, particularly relating to RCA; postwar Japanese-American business and informal diplomatic relations; and life in postwar Tokyo.

DuPont (China), Inc. was a firm established to manage the exports of dyestuffs manufactured in China by the DuPont Company's Organic Chemicals Department. The collection consists of materials from DuPont's Organic Chemicals Department in China and a group of reports and notebooks describing the beginnings of DuPont's dyestuffs ventures in East Asia.

The Glenn Reitmeier papers are a digital collection of emails, scans of memos and faxes, meeting notes, agendas, presentations, data tables, and even press clippings related to Reitmeier’s activities, forwarded by email or gleaned from the internet.

The collection follows Reitmeier’s role in creating commercially viable digital high definition television technology, standards, and hardware. The papers begin with materials from the Advanced Television Research Consortium (ATRC), which he led from his position at Sarnoff from 1989 until 1993. The bulk of the Reitmeier papers come from his time in the Grand Alliance from 1993 to 1996. Finally, there are materials from the immediate aftermath of the Grand Alliance including marketing plans for making HDTV profitable and business deals with Japanese manufacturers. The papers do not just represent the technical activities of Reitmeier’s career, however; there are also materials tracking the extensive political debates about standardizing and developing HDTV technology (for example, an email responding to Martin Scorsese's public critiques of the GA) and presentations given at various conferences and technology summits.

The Reitmeier papers are especially important for the inside look they offer into the regulatory process as a collaboration between government and various industries: electronics, consumer electronics, broadcasters, Hollywood, computing and other industries are all players in this story. Historians of technological development and path-dependency might be especially interested in the debate over interlace versus progressive scanning and transmission in HDTV. The co-creation of MPEG standards along with HDTV, told in both the first and second subseries, is another important story for those looking at the relationship between engineering, innovation, policy, and standardization.

One of Reitmeier's lab notebooks (1977-1979) can be found in Record group 26.

The Harry L. and Harvey P. Sommerer papers are primarily composed of Harvey P.'s papers, including a letterbook, Japanese business and identity cards, recreational photographs, and ephemera. The papers also include fifteen films from the 1930s, primarily in Japan.

Samuel Francis Du Pont (1803-1865) was a Rear Admiral in the United States Navy and fought in the Mexican-American War and the Civil War. He was the fourth child and second surviving son of Victor Marie du Pont (1767-1827) and his wife, Gabrielle Joséphine de la Fite de Pelleport (1770-1837). His papers document du Pont's professional and personal life against the background of the pre-Civil War service.
