Clodomiro Picado Twight

Clodomiro 'Clorito' Picado was born on April 17, 1887, to Costa Rican parents in San Marcos. Studying at the University of Paris (Sorbonne) and the Pasteur Institute, he specialized in botanical microbiology and venoms.

Returning to San José, Picado directed the Laboratory of the San Juan de Dios Hospital for over three decades. He produced revolutionary snake venom serums saving thousands of agricultural workers and documented antibiosis in moulds as early as 1927. In 1970, Costa Rica's premier biomedical research institution, the Instituto Clodomiro Picado, was founded in his honor.
