Jack Daniel’s grew from a Tennessee distilling business into one of the world’s best-known whiskey brands, closely tied to founder Jasper Newton “Jack” Daniel and to Nathan “Nearest” Green, the enslaved master distiller who taught Daniel the Lincoln County Process of charcoal filtering. After establishing a legally registered business in 1875, Daniel expanded production in Lynchburg, introduced the square bottle in 1897, and gained wider fame after a gold medal at the 1904 St. Louis World’s Fair. Despite shutdowns caused by Tennessee prohibition and wartime restrictions, the distillery resumed operations and became both a historic site and a global mass-market brand.
