Clodomiro Picado Twight

Clodomiro Picado Twight (April 17, 1887 – May 16, 1944), also known as "Clorito Picado", was a Costa Rican scientist who was internationally recognized for his pioneering research on snake venom and the development of various antivenins. His work on molds was a precursor to the formal discovery of penicillin and resulted in compounds which he used to treat patients at least one year before the re-discovery of penicillin by Alexander Fleming. He wrote over 115 works, mainly books and monographs.
