Carter Litchfield (1932-2007) an organic chemist who studied and specialized in edible fats and oils. Litchfield, born on February 18, 1932, earned a B.S. in chemical engineering from Rensselaer Polytechnic Institute, Troy, New York. Litchfield later earned Ph.D. in organic chemistry from Texas A&M after starting his professional career as a chemist for Procter & Gamble (P&G). During the mid- to late 1950s Litchfield worked in the Edible Research Section of the Chemical Division of P&G. His work there centered on shortening products like Crisco and margarine oils. Because of his work at Procter & Gamble, Litchfield developed an interest in the history of fatty materials, which he defined as high-calorie fats found in seeds and animals. Fatty oils include olive, linseed, soybean, cottonseed (all seed oils) as well as lard, tallow, and other animal body fats. Litchfield left P&G in 1960 to take a job as a research scientist at Texas A&M. After a few years at Texas A&M Litchfield decided to work towards his doctorate in organic chemistry.

Litchfield then spent nine years working at Rutgers University. His research activities revolved around soluble oils in marine mammals and aquatic sponges. Litchfield published his work on Amazon River dolphins in a 1970 article in Biomedical Life & Sciences. In 1972, Litchfield published the book Analysis of Triglycerides. While at Rutgers Litchfield founded Olearius Editions, a publication company dedicated to the history of vegetable oil and fat production. In 1979, Litchfield retired from Rutgers to pursue a new career researching and publishing works on the history of fatty oils.

Olearius Editions (named for the artisan in the Roman Empire who pressed oil from olives and sold it to the community) specialized in the publication of histories of the manufacture of vegetable oils and fats. Litchfield's first book, published in 1974 was an English translation of the 1836 Japanese work, Seiyu roku. One of Litchfield's most important Olearius publications was a book he co-authored, The Bethlehem Oil Mill, 1745-1934: German Technology in Early Pennsylvania (1984). The book featured first time translations of German documents detailing the craft and artisanship involved at the oil mill. His interest in oil mills extended well beyond Bethlehem, Pa. Litchfield researched and photographed oil mills all over the United States, Europe, and parts of the Middle East. Olearius Editions publications reflected Litchfield’s global scope with the publication of another translated work, History and Technology of Olive Oil in the Holy Land (1993). The Olearius version was partially translated from Hebrew with the addition of an original chapter not included in the original Hebrew publication. Litchfield also wrote and published through Olearius the definitive History of Oleomargarine Tax Stamps and Licenses in the United States (1988), a philatelic guide for the collecting of oleomargarine stamps. This book is known for its precise detail and dedication to an understudied topic.

As a member of the Society for Industrial Archeology (SIA) Litchfield regularly attended SIA meetings, functions, and conferences. He often presented papers to the SIA and sat on several committees, including the Vogel Prize committee. Litchfield researched the history of fats and fatty materials until his death on May 9, 2007 in Arlington, VA.

Carter Litchfield married his wife, Carol, in 1960. Like her husband, Carol Litchfield received a Ph.D. in biochemistry from Texas A&M and taught at Rutgers University. Carol Litchfield taught for 10 years before taking a position at the DuPont Company as head of Environmental Toxicology at Haskell Laboratory and then as Senior Scientist for its bioremediation subsidiary. She then started her own consulting company and worked for Chester Environmental prior to joining the George Mason University faculty in 1993.

Carter Litchfield died on May 9, 2007.
