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 ).

Early life

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.

Vanilla pollination

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 master, Mr. Beaumont, taught him the basics of botany, including how to fertilize flowers. From p. 233: "Elevé dans la maison de M. Féréol Beaumont Bellier, … de l'annoncer par la voie de la presse locale." (Raised in the house of Mr. Féréol Beaumont Bellier, living beside this learned man, and assiduous witness to his studies [that were] directed towards the natural sciences, Edmond became enamoured with botany, and his abilities — although they couldn't obtain, due to the complete absence of instruction, the development that they deserved — soon however drew the attention of Mr. Bellier. He took a liking to this little black boy who had tastes [that were] so similar to his own, and [he] initiated [Edmond] into the secrets of the lives of plants. The slave became so interested in the lessons of him who thus became in two senses his master [i.e., as owner and teacher] that at the age of hardly twelve, he had already become almost a naturalist; and to add even more to this phenomenon, Mr. Bellier taught Edmond the scientific names of the trees and flower that he possessed on his plantation, Bellevue ; so that the African botanist who spoke only Creole patois, who didn't even know the worth of the letters of our alphabet, named plants only in the scholarly language of Lineus and Jussieu. Indeed, this was not the least original and the least surprising aspect of the aptitude of this singular disciple of Flora. Edmond had seen his master practice fertilization among certain flowers; his constant and shrewd observations led him to try the same operations on vanilla. His attempts were crowned with complete success ; and when he made them known to Mr. Bellier, the latter, [who was] very pleased with such an important discovery, hastened to announce it by way of the local press.) 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.

Later life

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. He was convicted of stealing jewelry and sentenced to ten years in prison, but the sentence was commuted after five years when the governor granted him clemency in light of his enormous contribution to vanilla production in Réunion. Albius died in poverty in St. Suzanne in 1880.

In the media

Albius' story is explored in "The Enslaved Teen Who Cracked Vanilla’s Secret", an episode of Ideas on CBC Radio. Also in 2023 the French-Réunionese novelist Gaëlle Bélem published an award-winning historical novel Le fruit le plus rare : ou la vie d'Edmond Albius based on Albius's life. The story is also told on the BBC 'World's Table' from January 2024.
