Edmond Albius

Edmond Albius (c. 1829 – 9 August 1880) was a horticulturalist from Réunion. Born into slavery, Albius became an important figure in the cultivation of vanilla. At the age of 12, he invented a technique for pollinating vanilla orchids quickly and profitably. Albius's technique revolutionized the cultivation of vanilla and made it possible to profitably grow Vanilla planifolia away from its native habitat (Mexico to Brazil).

Albius was born in St. Suzanne, Réunion. His mother, an enslaved woman, died during his birth. The colonist keeping Edmond in slavery was Féréol Bellier Beaumont.

French colonists brought vanilla beans to Réunion and nearby Mauritius in the 1820s with the hope of starting production there. However, the vines were sterile because no insect would pollinate them. In 1837, Charles Morren, a professor of botany at the University of Liège in Belgium, published a method of hand-pollination, but his technique was slow and required too much effort to make cultivating vanilla a moneymaking proposition.

Albius's enslaver, Mr. Beaumont, taught him the basics of botany, including how to fertilize flowers. In 1841, Albius invented a method to quickly pollinate the vanilla orchid using a thin stick or blade of grass and a simple thumb gesture. Using the stick or grass blade, field hands lift the rostellum, the flap that separates the male anther from the female stigma, and then, with their thumbs, smear the sticky pollen from the anther over the stigma.

Albius's manual pollination method is still used today, as nearly all vanilla is pollinated by hand. After Albius's discovery, Réunion became for a time the world's largest supplier of vanilla. French colonists used Albius's technique in Madagascar to cultivate vanilla, and Madagascar remains the world's chief vanilla producer.

Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier.

In gratitude for – and in recognition of – his discovery, locals on Réunion attempted (unsuccessfully) to obtain a reward or a government stipend for Albius.

In 1848, France outlawed slavery in its colonies, and Albius left the plantation for St. Denis, where he worked as a kitchen servant. He adopted Albius as his new surname from alba "white" in reference to the vanilla orchid's colour.
