Stephen S. Chang Papers


  • 1933-2001; bulk, 1960-1988

Scope and Content Note

The Stephen S. Chang Papers consists of documents ranging in date from 1933 to 2001. The bulk of documents found in the collection were created from 1960 to 1988. The collection totals 13 cubic feet of records housed in 40 letter-sized manuscript boxes.

There is a broad representation of formats in the collection. The most frequently occurring formats are typed documents including correspondence, meeting minutes and agendas, reports, letters, patents and financial/budget plans. Handwritten notes are also found in the collection in addition to newspaper articles, photographs, negatives, programs and brochures. Acetate transparency slides used with overhead projectors were also found in the collection. Due to the unstable nature of acetate these slides have been photocopied onto acid free paper. Diagrams for laboratories and building layouts are included in the collection as well as machinery blue prints. The bulk of these materials are written in English. About 20% of the collection is written in Mandarin Chinese and a few documents are in German.

The strength of the Stephen S. Chang Papers lies in Series III: Research and Consulting which comprises twenty boxes of the collection. Dr. Chang's research and business dealings with the American Lecithin Company, Kabi Vitrum, Pharmacia and the Lever Brothers companies comprise a significant portion of the series. Many other companies are also documented but little in-depth information about these companies is included in the collection. In addition to research projects for the companies correspondence, reports and budget information are also represented. A significant amount of information relating to specific research is included in this series regarding phospholipids, antioxidants including rosemary, fat emulsion, lecithin and various oils including soybean. The majority of patent information found in the collection is also found in this series. Patent searches, dealings with patent attorneys and copies of Dr. Chang's patents are documented. Dr. Chang also kept copies of his patents with his personal documents and can be now found in Series I: Personal Papers.

The strengths of Series II: Professional Affiliations lie with information regarding the American Oil Chemists' Society, Institute of Food Technologists, and the Cathay Food Consulting Co. A large bulk of this series documents Dr. Chang's international food technology career. However most of this material is written in Mandarin Chinese such as materials regarding the Taiwan University Institute of Food Science & Technology, the Advisory Committee to the Taiwan Food Industry and the Joint Commission on Rural Reconstruction. With the help of a student from the East Asian Library in Alexander Library at Rutgers University the characters Dr. Chang used to write folder labels are translated into English using Pin Yin translations thus creating a general summary of the folders' contents. Business trips the Changs took to Taiwan, Hawaii, Florida etc. are also documented in Series II while vacations are documented in Series I: Personal Papers.

Series IV: Rutgers University Administration documents policies and procedures in use during the time Dr. Chang was chair of the Food Science Department (1977-1986). The series is also strong in its coverage of Food Science department issues during this period. This area of the collection documents plans for the Center for Advanced Food Technology and work done with the New Jersey Agricultural Experimentation Station and Cook College.

Due to the nature of Dr. Chang's work and consulting with other companies, Dr. Chang or the company issuing the documents labeled several documents "confidential" or "top secret." These documents were removed with a note left to indicate their original location and placed in Separated Material: Removed Confidential Items.

Biographical Sketch of Stephen S. Chang

Dr. Stephen S. Chang (1918-1996) is widely recognized for his contributions to the Food Technology field as he was a distinguished educator, researcher and inventor. He is renowned for his work in flavor and lipids and was the recipient of the highest award in lipid research, the American Oil Chemists' Society's Lipid Chemistry Award. In addition he received the most prestigious award in food technology, the Nicholas Appert Award from the Institute of Food Technologists.

Dr. Chang was born in China in 1918. He arrived in the United States in 1947 and later became a naturalized American citizen. Chang received his undergraduate degree from National Jinan University of Shanghai (1941), an M.S. degree in Organic Chemistry from Kansas State University (1949) and a Ph.D. in Food Science from the University of Illinois (1952). He spent several years in industry before he joined the Rutgers faculty in 1960. He went on to serve as Chair of the Food Science Department from 1977 to 1986. During his tenure at Rutgers, Dr. Chang served as National President of the American Oil Chemist's Society in 1970 and as Honorary President of the International Society for Fat Research in 1980. He received the Rutgers Board of Trustees Award for Excellence in Research in 1984, and the Rutgers University Award and Medal upon his retirement in 1988. Dr. Chang published over 100 articles, book chapters, and other works and was inventor or co-inventor of fifteen patents.

Dr. Chang was instrumental in exchanging food science information and technology with mainland China and Taiwan. He received the 1989 International Award from the Institute of Food Technologists and a special commendation from the Prime Minister of the People's Republic of China. His interactions with students in the classroom and the laboratories at Cook College, however, were Dr. Chang's most cherished achievements in his nearly forty year career. He helped many students launch their scientific careers.

After his retirement from Rutgers, the Changs endowed the Stephen and Lucy Chang Science Library at Cook College dedicated in October 1995. He endowed the Stephen S. Chang Award at the American Oil Chemists' Society in 1990 and the Stephen S. Chang Award at the Institute of Food Technologists in 1992. He also donated funds for educational buildings at the Anglo-Chinese College and at Hwa Nan Women's College. Both colleges are located at Fuzhou, Fujian, People's Republic of China. He established a scholarship fund for food science students at Jinan University at Guangzhou, Guangdong, People's Republic of China.

Born in China, Lucy Chang received a bachelor of science degree in chemistry from Hwa Nan Women's College in China. She received her D.D.S. degree from the University of Missouri in Kansas City. After marrying Stephen Chang in 1952, she served within the chemistry department of the University of Illinois and later joined the American Meat Institute Foundation. Thereafter, she devoted much of her time and energy assisting her husband in establishing his career.

Arrangement Note

The papers of Dr. Stephen S. Chang are arranged in the following series:

  1. I. Personal Papers
  2. II. Professional Affiliations
  3. III. Research and Consulting
  4. IV. Rutgers University Administration

Provenance Note

Dr. Chang compiled his documents in a general alphabetical filing system throughout his career. He sought to save materials relating to scientific research and patents, documents necessary to serve as an administrator at Rutgers University as well as documents and photographs relating to other aspects of his professional and international career. After his death in 1996, Lucy Chang, his wife, added elements to the collection such as scrapbooks including personal documents and photographs.

Upon Dr. Chang's retirement from Rutgers in 1988 the collection was stored in East Brunswick, New Jersey at the Chang's home. Mrs. Chang donated the collection to Rutgers University Special Collections and University Archives in 2004. A team from the University Archives went to the Chang home to create a preliminary inventory of the records and re-box the files for transport to Alexander Library.

Separated Material

Removed Confidential Items, 1961-1991

Boxes 41-42 (17 folders)

Arranged alphabetically by original series, subseries and folder label. These documents have been removed from their original locations in the collection because they were marked "Confidential" by either Dr. Chang or other creators. A note has been left in the document's place to inform researchers of its existence and removal. The note also serves as a placeholder if the time comes when the document is no longer sensitive and can be re-incorporated into the collection. The container list reflects the series where the document originally came from. Single documents were treated with micro-folders and grouped together under the original series name and a general folder title. The original location of these items is documented on the micro-folder. In some instances entire folders were removed from a series and placed in Removed Confidential Items. These folders also maintain original series name as well as folder titles. If, in the future the information is no longer sensitive the folder(s) may be re-incorporated into the series alphabetically by subseries or folder title.

Processing Note

The Chang collection arrived at Rutgers grouped into various sections. The first two sections were designated Kabi Vitrum and Pharmacia presumably by Dr. Chang in his filing cabinets. The remainder of the items were divided chronologically in bulk dates or places. These headings did not always correspond to the documents they represented, however. After going through the papers four significant series emerged. Dr. Chang's scrapbooks comprise Series I: Personal Papers. Kabi Vitrum, Pharmacia, consulting and other research are grouped together and given the series name Series III: Research and Consulting. In order to maintain Dr. Chang's original filing structure this series was divided into four subseries, Correspondence, Kabi Vitrum, Pharmacia, and Other Research, Patent and Literature. These were clear distinctions made by Dr. Chang. The remainder of the documents did not correspond to a subseries and are arranged alphabetically by folder title. Foreign and professional associations are grouped together as Series II: Professional Affiliations while Rutgers University policies, procedures and curriculum became Series IV: Rutgers University Administration.

Generally Dr. Chang arranged his folders alphabetically. Wherever possible Dr. Chang's original folder labels have been used and the folders filed alphabetically. Dr. Chang's original folder labels are enclosed in quotations on the folder. In many instances, however, the folder labels were abbreviations, incomplete or only made sense to the creator as a correlation between the label and documents inside could not be found. In these cases a label reflecting the documents was created or the original label was expanded upon to include more information. This was done to facilitate the use of the collection and adequately represent the documents. Dr. Chang labeled several folders with "A.C." It could not be discerned from the documents what exactly this acronym means as it could refer to an Advisory Committee, Agricultural Committee or Agricultural College. The number found in the lower left corner of the folder reflects the folder's original chronological placement in the collection. This allows one to recreate the original order of the folders if necessary.

The items are arranged chronologically inside the folders unless otherwise noted on the micro folders. Items with no date are found in the back of the folder. Some folders have no date because the item(s) inside are undated. Newspaper articles, acetate slides and information on acidic paper are photocopied to preserve the information. The originals have been discarded. Staples are removed from documents and replaced with PlastiKlips and/or micro folders. Loose photographs and negatives are sleeved. The scrapbooks are photocopied to preserve the original format of the items. The images and documents are now in photo sleeves, no longer in the scrapbooks. It was necessary to remove the items because the scrapbooks used "Magic Pages" containing a harmful adhesive to documents and photographs.
