Karl August

(1757 –1828), was the sovereign Duke of Saxe-Weimar and of Saxe-Eisenach (in personal union) from 1758, Duke of Saxe-Weimar-Eisenach from its creation (as a political union) in 1809, and grand duke from 1815 until his death. He is noted for the intellectual brilliance of his court.
One of the first acts of the young duke was to summon Goethe to Weimar, and in 1776 he was made a member of the privy council. “People of discernment,” the duke said, “congratulate me on possessing this man. His intellect, his genius is known. It makes no difference if the world is offended because I have made Dr Goethe a member of my most important collegium without his having passed through the stages of minor official professor and councilor of state.”
