Chlortetracycline (trade name Aureomycin, Lederle Laboratories) is a tetracycline antibiotic, the first tetracycline to be identified. It was discovered in 1945 at Lederle Laboratories under the supervision of Yellapragada Subbarow and Benjamin Minge Duggar. They were helped by Louis T. Wright, a surgeon who conducted this medication's first human experiments. Duggar identified the antibiotic as the product of an actinomycete he cultured from the soil of Sanborn Field at the University of Missouri. The organism was named Streptomyces aureofaciens and the isolated drug, Aureomycin, because of their golden color.
