When and why was the finger known as "the ring finger" called that?

Before medical science discovered how the circulatory system functioned, people believed that a vein ran directly from the fourth finger on the left hand to the heart. Because of the hand–heart connection, they chose the descriptive name vena amoris, Latin for the vein of love, for this particular vein.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
