The 27th of December is the birthday of Jean-Étienne de Boré, the man who first produced granulated sugar.
Jean-Étienne de Boré lived from 27 December 1740 to 2 February 1820.
He was the man who first commercially produced granulated sugar, in 1795.
He grew the sugar on a plantation in what is now Audobon Park in New Orleans, Louisiana.
Jean-Étienne had luck in producing granulated sugar the very first time he tried. He was able to 100,000 pounds (45,000 kg) of granulated sugar, as well as molasses as a byproduct, and turned a tidy profit in his very first year of making it.
Note, though, that the granulation process itself was actually invented by Norbert Rillieux, a local free man of color who worked for Boré.
