Biography of Llewelyn Williams

Llewelyn Williams (1901-1980) was an economic botanist, wood technologist, and an authority on plants that produce latex used commercially for gums and rubbers.

He was born in Conway, Wales and obtained his B.Sc. (1924), M.Sc. (1935), and D.Sc. (1963) at the University of Wales, specializing in tropical American woods and forest products. In 1928 he did post-graduate studies under Dr. Samuel J. Record of the Yale University School of Forestry. In the course of his career he collected and studied latex-bearing plants and other rainforest products in tropical regions throughout the word for scientific and commercial purposes. He conducted extensive field investigations in the Amazon, Caura, and Orinoco River basins of northern South America, and later traveled to Africa, Southeast Asia, India, and the Philippine Islands.

From 1924 to 1926 he managed a 700-acre tea estate in Assam, India before receiving an appointment as Dendrologist at the Field Museum of Natural History in Chicago, Illinois. His career at the Field Museum spanned 26 years (1926-52), where he was Curator of Economic Botany from 1938. During this time he undertook several assignments on leave of absence, as Research Botanist for the Ministry of Agriculture and Animal Husbandry of Venezuela (1938-40; 1941-42) and as Senior Field Technician for a U.S. government agency, the Rubber Development Corporation (1942-45). The latter assignment was an emergency World War II project to recruit and train rubber-tappers to locate and extract Hevea rubber in the Upper Orinoco River valley.

After the war he conducted fieldwork (1945-55) for the Dreyfus Corporation, a Wrigley Chewing Gum Co. subsidiary, to locate natural sources of gums, rubber, resins, and waxes in tropical forests. He remained a consultant for the Wrigley Company on tropical forest products from 1956 to 1960. In 1961 the USDA recruited Dr. Williams for an appointment as Senior Economic Botanist, Crops Research Division. In this capacity he was engaged in research (1963-67) on the effects of chemical defoliants with the USDA Agricultural Research Service under contract with the Advanced Research Projects Agency (U.S. Dept. of Defense). Dr. Williams conducted an intensive study of forest and agricultural zones, including aerial reconnaissance, in Thailand and other countries of Southeast Asia, and he published a comparative study, Forests of Southeast Asia, Puerto Rico, and Texas (1967). In 1966 he participated in a USDA project under the auspices of the International Agricultural Development Service to evaluate agriculture and forest resources in the Republic of Dahomey, Africa.

Llewelyn Williams was a seasoned explorer, a world authority on botanical products of tropical rainforests, and a man firmly dedicated to his Welsh heritage. He did his own photography and amassed a substantial collection of photos that document the extraction and processing of gums, rubbers, resins, and related material from tropical plants. He published hundreds of scientific articles and industrial reports on wood species and products based on firsthand field investigations and surveys. He was a member of the International Association of Wood Anatomists from its founding in 1930 and Secretary for the Society for Economic Botany. Dr. Williams died in 1980, at the age of 79.


Scope and Content

The collection consists of correspondence, manuscripts and typescripts, research papers, personal papers, maps, travel memorabilia, audio tape recordings (dictaphone), film (16mm), artifacts, and photographic material which includes positive and negative prints, glass negatives, and color slides. A portion of the photography appears in scrapbooks and bound publications. The collection covers most of Dr. Williams' career including botanical research and fieldwork with the Chicago (Field) Museum of Natural History, Rubber Development Corporation, Dreyfus Corporation (a subsidiary of the Wrigley Chewing Gum Co.), and the U.S. Department of Agriculture (USDA). A substantial portion of the research papers and photography documents worldwide botanical exploration in the tropics, especially in the Amazon and Orinoco River basins of South America and in Thailand. The personal papers document Dr. Williams' Welsh heritage and his affiliations to various Welsh, fraternal, and religious organizations. His field notebooks are located in the NYBG Collectors' Field Notebooks collection.

Series 3. Research Papers.

Scope and Content:

The Research Papers consist of subject files on (a) latex-yielding plant species; (b) gum and rubber products; (c) tropical woods; (d) agricultural and forest resources (by country); and (e) genus files. There are 13 files of bibliographic material, 22 files of field exploration reports (primarily from Brazil), and 9 files of photo indices (see Series 6: Photographic Material). Thirty-eight files of data entitled "Field Collection Numbers" are organized regionally and/or sequentially (e.g. "18000" sequence). Of these there is comprehensive collection data on Peruvian woods (1929-1930), Orinoco River basin plants (1939-1942), Plantas Venezolanos (1938), and Plantas Recogidas en Guayana (1940) among several others. These files consist of transcriptions of field notebook data for which see Series 12: Field Notebooks below.

Research milestones of Dr. Williams' career are documented with data on the Marshall Field Amazon Expedition (1929), Rubber Development Corporation reports on sources of South America rubber during World War II (1942-46), Dreyfus Corporation reports and memoranda, and research on chicle and chilte for the Wrigley Chewing Gum Co. Several files relate to government research under the auspices of the USDA on the effects of herbicides and patterns of successional forest growth after defoliation. For this project see under Advanced Research Projects Agency; Forests of Southeast Asia, Puerto Rico, and Texas; Thailand; Vietnam, and various USDA files. An index card file is located in Box 18, and oversize documents in Boxes 19-22.

Series 4. Personal Papers.

Scope and Content:

The Personal Papers consist of biographical writings, clippings, correspondence, diaries, memorabilia, typescripts of short stories, and personal records (e.g. employment, financial, genealogical, legal, and medical). There are 15 correspondence files, including four files with Dr. Williams' wife, Mary Williams. The latter provide personal information about events at home and about detailed travel itineraries, hardships, personnel, and accomplishments from field locations throughout the world. Several files contain records and memorabilia relating to Dr. Williams' membership in religious and fraternal organizations and his participation in a variety of Welsh and Welsh-American organizations. Notable items include diaries (English and Spanish) of field trips to the upper Orinoco River basin (1941-42) and to the Peruvian Amazon (1959) and a missionary's account of travel to the North Lushai Hills of Assam, India (1924).

Series 6. Photographic Material.

Scope and Content:

There are an estimated 11,000+ photographic images in the collection in the form of positive and negative prints, color slides, and glass slides. The photography documents botanical expeditions and fieldwork, tapping and production operations of latex-bearing trees, identity and forms of plant species (especially those producing gums and rubbers), plant cultivation, and regional surveys of forest and agricultural habitats. Comprehensive regional surveys in Thailand, Puerto Rico, and the Peruvian Amazon include aerial photography. Some of the photographic material consists of line drawings of plant species, diagrams, and maps. Much of the photography is captioned and has been used in published material (Series 10), documenting a variety of research projects and botanical expeditions throughout the tropics. See Series 3: Research Papers for a photo index list.

Photos appear in single shots, numbered photographic sequences, scrapbooks (intact and disassembled), and suspended on hanging mounts ("Fotofolio" books). There are four boxes of color slides, some of which duplicates other photographic material. Images are organized alphabetically by plant species, botanical product, country, or location. Positive and negative prints have been cross-referenced with Dr. Williams' identifying numbers where possible. Major pictorial sequences have been coded systematically as follows: D = Dahomey; E1 = Puerto Rico defoliation study; IC = Indochina; M = Manilkara; PR = Puerto Rico; T = Texas; #-63/64 = Thailand, 1963/64; #-65 = Thailand, 1965; W = Vanilla.

Photographic subjects include surveys of latex-yielding species (e.g. Achras, Castilloa, Cnidoscolus, Couma, Dyera, Hevea, Manilkara, Palaquium, Sapium et al) and latex products (e.g. balata, chicle, chilte, gutta-percha, jelutong, leche-caspi et al). There are photo surveys of the Marshall Field Amazon Expedition (1929); exploration of South America during World War II; comparative studies of the forest resources of Puerto Rico, Texas, and Thailand relating to herbicide testing; and the economic botany of the Caura and Orinoco Valleys, Venezuela. Much of the collection has ethnographic significance as Dr. Williams photographed individuals of aboriginal cultures in the context of their aesthetic, material, economic, and social culture. There are portraits of Dr. Williams, his wife and family, and group photos of professional organizations. Oversize photos are located in Boxes 33 and 34. Photographic material can also be found in Series 2: Manuscripts & Typescripts; Series 3: Research Papers; and Series 4: Personal Papers.

Series 7. Maps.

Scope and Content:

There are two boxes containing maps in a variety of formats and media. Most of the maps are housed in file folders and are of photographic quality (glossy and matte) or of paper and board. There are 13 oversize maps, both published and hand-drawn. Subjects include travel routes, encampments, forest and agricultural zones, topography, and physical and national boundaries. Several are marked and annotated. Most are country maps, especially of Southeast Asia and South America; there are regional and local maps as well. Notable maps describe botanical areas studied by Dr. Williams, travel routes in the Orinoco and Peruvian Amazon River basins, and a wide variety of forest and agricultural zones and types in Thailand. There is one composite aeronautical chart of the Isthmus of Tehuantepec, Mexico. Negatives of photo-quality maps (and smaller photo maps) are located in Series 6: Photographic Material. The collection complements and supports botanical and expedition information of Series 2: Manuscripts & Typescripts, and Series 3: Research Papers.

Arranged alphabetically or by assigned number.
