Five specimens of Fragaria chiloensis were brought back from South America by Amédée-François Frézier, permanently altering the botanical landscape of the Old World. Born in 1682, this versatile professional served the Kingdom of France as an engineer, cartographer, and military officer, leaving behind a legacy rooted in rigorous scientific observation and tactical intelligence gathering across three continents.
Early Scientific Pursuits
Raised in Chambéry, he rejected a legal career, opting to study theology and science at the University of Paris. His academic background included the thesis Treatise on Navigation and the Elements of Astronomy. Further travels in Italy deepened his knowledge of art and architecture, a skillset he subsequently integrated into the design of complex defensive fortifications and military structures.

During his tenure as a military engineer at Saint-Malo, he authored the 1706 text Traité des feux d'artifice pour le spectacle. This work provided standardized instructions for manufacturing decorative fireworks, focusing on civilian rather than military applications. The analytical rigor demonstrated in this publication led to his transfer into the French military intelligence corps.
The South American Expedition
On 7 January 1712, he departed for South America aboard the St. Joseph to conduct a high-stakes reconnaissance mission. Operating under the guise of a merchant, he mapped key ports and fortresses in Chile and Peru, while simultaneously recording geographical, botanical, and ethnographic data. His findings were published in 1716 as Relation du voyage de la mer du Sud, a text that corrected previous hydrographical errors and earned him royal recognition.
Engineering and Academic Legacy
Following his return to France in 1714, he was tasked with fortifying Hispaniola in 1719. Later career highlights included his service at Philippsburg and Landau, where he oversaw the construction of twenty-six defense structures. He was appointed a Knight of the Royal and Military Order of Saint Louis in 1728, and in 1752, he was elected to the French Academy of Sciences.
