John Stein Caldwell, age 78, internationally noted entomologist who specialized in the Homoptera and described numerous species of insects
as new to science, died 2 March 1990.
Dr. Caldwell joined The Ohio Academy of Science (1949), affiliated with Section Zoology, was elected a Fellow (1966), and became an emeritus member (1984).
Born 8 October 1911, in Circleville, OH, John was the son of Felix Renick and Fannie (Stein) Caldwell. After receiving his secondary education in Circleville, except for attending a school in Sarasota, FL, for one year (1920-1921), he attended The Ohio State University where he earned the B.S. (1933), M.S. (1934), and a PhD in Entomology (1938).
Caldwell completed a special research problem under the supervision of noted entomologist, Dwight M. DeLong, which work later developed into his master's thesis, "Studies of Leafhopper Hibernation in Ohio (Homoptera: Cicadellidae)." His subsequent systematic studies on Homoptera which were begun as a project for the Ohio Biological Survey under the direction of Prof. Herbert Osborn, formed the basis for his doctoral research under DeLong's supervision. Much of the data in his dissertation, "The Jumping Plantlice of Ohio (Homoptera: Chermidae)," was preceded in publication with the same title in a monograph (Ohio Biological Survey, Bulletin 34, Vol. VI, No. 5. 1938. pp. 227-281).
While a doctorate student, Caldwell also served as an Assistant in the Ohio Biological Survey (1934-1938). Professional positions held were:
Specialist in charge of Homoptera, Division of Insect Identification, U.S. Department of Agriculture (1941-1945); Visiting Scientist, Rio Piedras, Puerto Rico (1947); and practicing entomologist in succeeding years.
Some of Caldwell's honors were his election to Sigma Xi and Gamma Sigma Delta. In the Entomological Society of America he was a Fellow and Life Member.
During summers (1933-1938) John worked on a farm which provided him the opportunity and substantial time to collect and study insects. After receiving his doctorate degree, he continued his studies of the homopteran insects and conducted research in Puerto Rico. Among his extensive scientific writings, published in English and Spanish, were monographs on homopterans of Mexico, West Indies, Ohio, and other regions of North America.
Dr. Caldwell married (1936) Emily B. Zaenglein who preceded him in death and is survived by his daughter Emilie C. Stewart. His burial was arranged by the Mader-Peters-Reams Funeral Home, Circleville, OH, but no services were held in compliance with his request. Memorial contributions may be given to the American Cancer Society. ~WILLIAM R. BURK
