Biography

Herrera was born in Mexico City, the son of a well-known naturalist. He studied Pharmacy at the National School of Medicine, graduating in 1889 by which time he had already published several papers in Zoology and Ornithology.

Ideas

He developed an experimental science called Plasmogeny, concerned with the origin of protoplasm, the living material of which all animals and plants are made. He reasoned that since life was the result of purely physico-chemical phenomena, it should be possible to create a structure with similar properties to natural protoplasm out of relatively simple organic and inorganic compounds in the laboratory. To this end he conducted experiments to create artificial cells ("protocells") using substances such as Olive Oil, Sodium Hydroxide, Gasoline, Thiocyanate etc.

Books

He published his ideas in books such as Recueil des Lois de la Biologie Generale ("Collection of the General Laws of Biology") in 1897 and Nociones de Biologia in 1904 (reprinted in 1924 as Biologica y Plasmogenia - "Biology and Plasmogeny"). His ideas on plasmogeny were further elaborated in Una Nueva Ciencia - La Plasmogenia ("A New Science - Plasmogeny", 1924) and a shorter version followed in 1932, La Plasmogenia – Nueva Ciencia del Origin de la Vida ("Plasmogeny - The New Science of the Origin of Life"). His experiments were published in two scientific journals which he founded - Gaceta de Plasmogenia (in Spanish) and Bulletin du Laboratoire de Plasmogenie (in French). He also wrote a number of other scientific texts.

Several of his books have now appeared in English translation.

Eponyms

Three reptiles are named in his honor: Kinosternon herrerai (Herrera's mud turtle), Barisia herrerae (Herrera's alligator lizard), and Lampropeltis zonata herrerae (Todos Santos Island kingsnake).
