 Biographical Note

Charles Wilson Suggs was born in 1928. He received a B.S.A.E. in 1949 from North Carolina State College (later North Carolina State University). After working some years in industry, he returned for graduate studies. In 1959 he received the first Ph.D. awarded by the college's Department of Biological and Agricultural Engineering. He was then appointed to the faculty.

Suggs's research interests were mechanization, controls, and human factors engineering. He developed one of the first mechanical tobacco leaf harvesters, in particular the rubber leaf stripper. He and Robert W. Wilson were granted a United States patent on the leaf removal device, which eventually was used on most commercial manufactured harvesters in the United States.

Suggs's human-factors research focused on the influence of environmental factors on response, such as the influence of vibration and noise on equipment operators.

During the 1960s Suggs was involved in the university's Ford Foundation project to help strengthen post-graduate training and research at the Indian Institute of Technology at Kharagpur, India. In 1967 he played a significant role in the establishment of the North Carolina Mu Chapter of Alpha Epsilon, the honor society of the American Society of Agricultural Engineers (ASEA). After his retirement in the 1990s he was appointed professor emeritus.

 Scope and Content Note

This collection contains Charles W. Suggs's research materials. Included are notes, data, publications, papers presented, reports, photographs, and sketches, primarily on the topics of tobacco mechanization (tobacco harvesters and transplanters) and equipment ergonomics. Some documentation from Dr. Bill Splinter, who was Suggs's research partner during the 1950s and 1960s, has been removed and put in the William E. Splinter Papers (MC 00091).

 Organization of the Collection

The collection is broken down into eight series. Series 1, Growth and Harvesting contains articles, reprints, photographs, and other data regarding the growth and harvesting of tobacco. Series 2, Physical Characteristics and Properties contains information on the the characteristics of both tobacco plants and the equipment used in raising and harvesting them. Series 3, Fertilization Studies contains materials on the effects of fertilization on tobacco growth and quality. Series 4, Dusting and Spraying contains materials on the effects of dusting and spraying on tobacco growth and quality. Series 5, Publications contains the research files for articles Suggs authored and co-authored. Series 6, Presentations contains the research files and transcripts for presentations Suggs gave. Series 7, Teaching and University Activities contains materials corresponding to Suggs's activities within the Department of Biological and Agricultural Engineering. Series 8, Other Materials contains materials not directly corresponding to any of the preceding series.

Throughout the collection, items in each series are arranged alphabetically by title, and then chronologically thereafter.
