J. G. Hamann

Johann Georg Hamann was a German pietist[?] protestant, thinker, and friend of the philosopher Immanuel Kant. His distrust of reason led him conclude that a childlike faith in God was the only solution to the vexing problems of philosophy. Also known by the epithet Magus of the North, he was one of the precipitating forces for the counter-enlightenment[?].

He defended the letter h in a pamphlet New Apology of the Letter H.
