Benjamin Minge Duggar (September 1, 1872 – September 10, 1956) was an American plant physiologist.[1][2]: 72 Surprisingly, he is best remembered for his contribution to another discipline, through his discovery in 1945 of chlortetracycline (Aureomycin), the first of the tetracycline antibiotics, from a soil bacterium growing in allotment soil.[3]
Duggar published many articles and books on a wide range of topics including mycology, mushroom growing, and plant physiology and pathology.[5][6] He wrote extensively on plant diseases including Ravenelia, Rhizoctonia,[5] cotton root rot disease, crown gall, and particularly tobacco mosaic virus.[4] His comprehensive American textbook on plant pathology Fungous Diseases of Plants (1909') became a standard text on the topic.[5][7] It was followed by the textbook Plant Physiology (1911)[5][8]
After becoming an Emeritus Professor, he continued to carry out research. One project was with Lederle Laboratories, part of American Cyanamid, looking for a treatment for malaria based on a species of Rhododendron which he found at the New York Botanical Gardens. Another project resulted in the discovery of Streptomyces aureus n. sp. a fungus producing a strong antibiotic. As a result of his work on chlortetracycline (Aureomycin), the first of the tetracycline antibiotics, he personally met with both the Pope and the Mikado of Japan.[4]
