Alphonse de Candolle

Born in Paris in 1806 and later active in Geneva, Alphonse de Candolle was a French-Swiss botanist and the son of the noted botanist Augustin Pyramus de Candolle. He became a leading scholar in his own right, continuing and expanding the family’s major botanical projects.

He is especially remembered for his work in phytogeography, the study of plant distribution, where he used not only botanical evidence but also historical and archaeological clues to think about the origins of plants. He also contributed to the vast Prodromus systematis naturalis regni vegetabilis, an ambitious effort to classify known plant species.

Readers may also know him through Origin of Cultivated Plants, a book that explored where many useful crop plants first came from. Its mix of botany, history, and everyday human life helped make his science feel broad, practical, and deeply connected to the world people live in.
