Francisco Hernández de Toledo facts for kids
Francisco Hernández de Toledo (born 1514 in La Puebla de Montalbán, Toledo, Spain – died 1587 in Madrid, Spain) was a Spanish doctor and scientist. He was known for studying nature and for being the personal physician to the King of Spain.
Hernández was one of the first Spanish doctors during the Renaissance to follow the medical ideas of ancient doctors like Hippocrates and Galen. He studied medicine and botany (the study of plants) at the University of Alcalá. He became well-known for his work on medicinal plants and for translating an important book about natural history. In 1567, he became the personal doctor for King Philip II.

Exploring the New World: A Scientific Journey
In 1570, King Philip II sent Hernández on a special trip to the New World (which included parts of modern-day Mexico). This was the first scientific mission of its kind. His job was to study the plants and animals there, especially those used for medicine.
Hernández traveled for seven years, collecting and describing about 3,000 different species. His son, Juan, joined him on this journey. He also talked to the local people through translators to learn about their traditional medicines.
Working with Local Artists and Doctors
During his trip, three local painters – Antón, Baltazar Elías, and Pedro Vázquez – helped Hernández draw the plants and animals he found. These drawings were very important for his research.
In 1576, Hernández also helped doctors in Mexico study a serious sickness called cocoliztli (which means "pest" in the Nahuatl language). He carefully described the symptoms of this illness.
Discovering New Plants
Hernández described over 3,000 Mexican plants. This was a huge achievement because no one had ever collected so much information about plants before. His work helped Europeans learn about and use these new plants.
Since there were no European names for many of these plants, he often used their native names, mostly from the Nahuatl language. He also grouped plants by their native names or compared them to plants already known in Europe.
Important Plants He Described
Some of the important plants Hernández described for the first time include:
- Vanilla: He wrote the first detailed account of this plant.
- Corn: He dedicated long chapters to describing different types of corn.
- Cacao: He described four varieties of the plant used to make chocolate.
- Tobacco
- Chilis
- Tomatoes: He wrote four chapters about different kinds of tomatoes.
- Cacti: He described many types of cacti in 14 chapters.
Hernández's Lasting Impact
Scientists today still study Francisco Hernández's work. They look at how he helped botany (the study of plants) and materia medica (the study of medicinal substances). His descriptions of vanilla, tomato, and corn are especially important.
His work also shows how local Mexican medicine traditions have continued over time, even today in Mexico and parts of the United States.
Remembering Francisco Hernández
Francisco Hernández is honored in the scientific names of two types of lizards: Corytophanes hernandesii and Phrynosoma hernandesi.
A plant genus called Hernandia is also named after him. This shows how important his contributions were to the study of plants.
