1517–1587
A court physician to Philip II, this pioneering Spanish naturalist led one of the first major scientific studies of the Americas. His work in New Spain brought European readers a vast new record of plants, animals, and healing traditions.

Born in La Puebla de Montalbán in the Toledo region around 1515–1517, Francisco Hernández trained as a physician and became known for his learning in medicine and natural history. He later served at the court of Philip II of Spain, building a reputation that reached far beyond ordinary medical practice.
Hernández is best remembered for the royal expedition that took him to New Spain in the 1570s. Traveling through what is now Mexico, he studied local plants, animals, and minerals and recorded Indigenous knowledge about their uses, especially in medicine. That work is often seen as an early landmark in the scientific study of the natural world in the Americas.
Although much of his research had a complicated publication history after his death in 1587, his legacy remained strong. He is still remembered as a bridge between Renaissance medicine, botanical exploration, and the exchange of knowledge between Europe and the Americas.
