Edmond Albius, an enslaved boy on Réunion (then Bourbon), discovered how to hand-pollinate vanilla orchids in 1841 using a simple hand-pollination technique still used by growers worldwide today. His achievement reveals how enslaved people possessed and advanced botanical knowledge, often through practical experimentation and oral transmission. However, despite transforming vanilla from a rare Mexican spice into a global commodity, Edmond was never granted freedom by his enslavers. His story sits within a broader history of enslaved people across the Indian Ocean and the Americas contributing significant knowledge, often without recognition or reward. However, Edmond was eventually freed following France’s 1848 abolition of slavery.
