Jean Nicolas Bréon
Jean Nicolas Bréon, often known as Nicolas Bréon, was a noted French plant collector and botanist.
From 1809 he worked as a student gardener at the Muséum national d'histoire naturelle in Paris, later serving as a botanist/gardener at the botanical garden in Ajaccio. In February 1815 he was named a gardener-botanist of the French Navy. Bréon was the first director of the Jardin du Roy in the Île Bourbon. During his time on Réunion, he organized several botanical trips to Madagascar, the Maldives and the Arabian Peninsula.
The genus Breonia was named in his honor by botanist Achille Richard — the genus Breonadia is most likely named after him.
