Reuchlin, John. A great German philosopher and philologist, Kabbalist and scholar. He was born at Pfortzheim in Germany, in 1455, and early in youth was a diplomat. At one period of his life he held the high office of judge of the tribunal at Tubingen, where he remained for eleven years. He was also the preceptor of Melancthon, and was greatly persecuted by the clergy for his glorification of the Hebrew Kabbala, though at the same time called the "Father of the Reformation." He died in 1522, in great poverty, the common fate of all who in those days went against the dead-letter of the Church.
