Although Victor Schoelcher as born on July 22, Schœlcher Day is celebrated in Martinique every July 21. I’m not sure why.
Victor Schoelcher was a French abolitionist writer in the 19th century. He was born in Paris in 1804 into a family of porcelain manufacturers and sent to the Americas in 1829-30 to work in the family business.
He visited Mexico, Cuba, and the southern United States where he witnessed the slave trade. This set him on a journalistic career to expose and eliminate this atrocity. Slavery officially ended in the French West Indies in 1848.
