León Mª Guerrero, “lion” scientist

Dr. León Mª Guerrero, the Father of Philippine Pharmacy.

From the illustrious and remarkable Spanish-speaking Casa de los Guerrero comes another Filipino genius: León Mª Guerrero (1853-1935), scientist brother of artist Lorenzo Guerrero and grandfather of diplomat/writer León María Guerrero (his namesake, author of the opus The First Filipino, 1962). Today is his birth anniversary.

Below is a brief biographical sketch of the the man who is considered as the Father of Philippine Pharmacy and Botany. It is again written by Héctor K. Villaroel (from the 1965 book Eminent Filipinos which was published by the National Historical Commission, a precursor of today’s National Historical Institute).

LEÓN MARÍA GUERRERO
(1853-1935)

Born on January 21, 1853 at Ermita, Manila, Dr. León María Guerrero was first among the many Filipinos to put the Philippines on the scientific map of the world.

A man of astounding scientific ability, he finished pharmacy in the University of Santo Tomás in 1876, specializing in pharmacology and botany, particularly the study of flowers. Later, he was awarded the degree of Licentiate in Pharmacy, the highest degree in that line at that time.

In 1887, he became a professor in pharmacy and botany and chemical technician of the Supreme Court in 1888.

During the Revolution, he assumed the editorship of the República Filipina; and upon the founding of the short-lived Philippine Republic University, he served as its dean and professor in pharmacy. Likewise, he was a delegate of three provinces to the Malolos Congress and representative to the first Philippine National Assembly in 1907.

Pursuing other fields of study, like zoology, ornithology, and lepidopterology, he wrote and published several penetrating and brilliant scientific papers which attracted the admiration and respect of Spain and other Spanish-speaking countries.

He died on April 13, 1935.
