Karl August Folkers (September 1, 1906 – December 7, 1997) was an American biochemist who made major contributions to the isolation and identification of bioactive natural products.[2][1]

Career

Folkers graduated from the College of Liberal Arts and Sciences at the

University of Illinois in 1928. In 1986, the institution awarded him its Alumni Achievement Award.[3]

His career was mainly spent at

cathomycin in 1955.[5] His team also isolated the antibiotic cycloserine.[6] In 1958 his Merck team determined the structure of coenzyme Q10.[7]

He later served as director of the Institute of Biomedical Research at the University of Texas at Austin, where he was also Ashbel Smith Professor of Chemistry.[3]

In recognition for his scientific contributions, he received the Perkin Medal in 1960,[8] the William H. Nichols Medal in 1967,[9] the Priestley Medal in 1986, and the National Medal of Science in 1990.
