Overview and metadata sections
James Cloyd Downs (1885-1957) was an American chemical engineer. Born in Newark, New Jersey on November 6, 1885, Downs earned his B.S. in Electrical Engineering from Cooper Union for the Advancement of Science and Art (1904). After earning his degree, he worked for New York Edison Company and Acker Process Company.
In 1907, Downs was hired by Niagara Electro Chemical Company, which soon merged with Roessler & Hasslacher Chemical Company. At Roessler & Hasslacher, Downs conducted research on McNitt sodium cells. He also served as Plant Manager of the firm's sodium plant in St. Albans, West Virginia for a time.
At Roessler & Hasslacher, Downs was best known for his invention of the Downs Cell. Invented in 1922, the Downs Cell is an apparatus used for the electrolytic production of metallic sodium and chlorine from molten salt (NaCl). The Downs Cell replaced the less efficient Castner Process and allowed for production of larger quantities of sodium. The sodium obtained through this apparatus is used for numerous applications, including the production of sodium cyanide, sodium peroxide, dyes, and pharmaceuticals. Downs was awarded a United States patent for the Downs Cell in 1924 and the rights to this patent were initially assigned to Roessler & Hasslacher. The patent rights for the Downs Cell later passed to E.I. du Pont de Nemours & Company (DuPont), which purchased Roessler & Hasslacher in 1930.
Downs was diagnosed with tuberculosis in 1923, which ultimately forced his early retirement from Roessler & Hasslacher in 1926. From 1926 to 1956, he lived in Saranac Lake, New York and served as a consultant for several chemical firms, including DuPont and National Distillers Chemical Corporation. Downs was awarded the Jacob F. Schoellkopf Medal by the Western New York Section of the American Chemical Society in 1934. He was also noted for being the father of Wilbur G. Downs (1913-1991), a well-known virologist and naturalist.
James Cloyd Downs passed away in Eugene, Oregon on December 18, 1957.

Collection Inventory
Arranged chronologically by date, this series contains an incomplete set of personal diaries kept by James Cloyd Downs between 1914 and his death in 1957. These diaries mainly document his everyday activities during his retirement in Saranac Lake, New York. The diaries from 1914 and 1923 provide some documentation of Downs' work at Roessler & Hasslacher Chemical Company. A small amount of information regarding Downs' consultant work for various clients, including DuPont and National Distillers Chemical Corporation, is also found in these diaries. Downs' observations of historical events of his time, including United States presidential elections and World War II, are also recorded here.
The actual diaries make up the bulk of the materials in this series. An index compiled by Downs' granddaughter Helen Downs Haller, which lists notable entries in the diaries is also found in this series. Small amounts of miscellaneous accompanying materials found inside of the diaries, including, but not limited to, photocopied newspaper clippings, magazine clippings, notes, and business cards are preserved here as well.
Arranged alphabetically by subject, this series contains James Cloyd Downs' correspondence files. The files in this series provide a very limited amount of information regarding Downs' personal and business affairs. Single files containing Downs' correspondence with Niagara Electro Chemical Company and Roessler & Hasslacher Chemical Company are found in this series. A file containing correspondence regarding Downs' being awarded the Jacob F. Schoellkopf Medal is also preserved here.
Arranged alphabetically by subject, this series contains James Cloyd Downs' files concerning the Downs Cell, which he invented in 1922 and for which he was awarded a United States patent in 1924. The files in this series contain a limited amount of technical information about the Downs Cell. A small amount of information regarding the use of the Downs Cell within the chemical industry (including by Roessler & Hasslacher Chemical Company and DuPont) is also preserved here.
The contents of the Downs Cell Files include, but are not limited to, blueprints, drawings, correspondence, notes, and a copy of the United States patent awarded to Downs.
Arranged alphabetically by subject, this series contains miscellaneous files collected by James Cloyd Downs and his granddaughter Helen Downs Haller. Four of the files in this series contain information concerning James Cloyd Downs himself. Three files concerning Clarkson College of Technology's "Fundamentals of Radio," an Engineering, Science, and Management War Training course completed by Downs during World War II, are also present in this series. A single file containing a college chemical engineering class paper written by Helen Downs Haller is also preserved here.
The contents of the files in this series consist of a variety of materials, including, but not limited to, class handouts, notes, certificates, photocopied newspaper clippings, magazine clippings, webpage printouts, and a college class paper.
Arranged alphabetically by subject, this series contains printed materials collected by James Cloyd Downs. A majority of the materials in this series concern sodium production and chemical companies for whom he was an employee or consultant (including Roessler & Hasslacher Chemical Company, DuPont, and National Distillers Chemical Corporation). A small amount of materials regarding miscellaneous subjects Downs had a personal interest in are also preserved here.
The contents of the Printed Materials series consist of photocopied newspaper clippings, magazine clippings, publications, an article reprint, and a table of contents.
This series contains photographs collected by James Cloyd Downs. The contents of this series include images of Downs himself, National Distillers Chemical Corporation's sodium plant in Ashtabula, Ohio, and Downs Cells used at Roessler & Hasslacher Chemical Company's plant in Niagara Falls, New York.
