At Dan Call's farm, Dan Call, a Lutheran lay minister and Confederate soldier, housed a young Jasper "Jack" Daniel. Daniel learned distilling from Call's enslaved distiller Nearest Green, born c. 1820, whom Call called “the best whiskey maker that I know.” When Daniel became a full partner in the distillery in 1866 and later established his own distillery in 1875, he hired three of Green's sons, and many generations of Green's descendants continued to work for the distillery. Nearest Green is considered the first known African American master distiller of Tennessee Whiskey.
