About
John Clark Sheehan (23 September 1915 – 21 March 1992) was an American organic chemist whose work on synthetic penicillin led to tailor-made forms of the drug. After nine years of hard work at the Massachusetts Institute of Technology (M.I.T.), he became the first to discover a practical method for synthesizing penicillin V. While achieving total synthesis, Sheehan also produced an intermediate compound, 6-aminopenicillanic acid, which turned out to be the foundation of hundreds of kinds of synthetic penicillin. Dr. Sheehan's research on synthetic penicillin paved the way for the development of customized forms of the lifesaving antibiotic that target specific bacteria. Over the four decades he worked at M.I.T., Sheehan came to hold over 30 patents, including the invention of ampicillin, a commonly used semi-synthetic penicillin that is taken orally rather than by injection. His research covered not only penicillin, but also peptides, other antibiotics, alkaloids, and steroids.
