Winckler, John Joseph, a German Pietist, was born at Luckau, in Saxony, December 23, 1670. He was at first a pastor at Magdeburg, then a chaplain in the Protestant army, accompanying the troops to Holland and Italy, and at length returned to Magdeburg and became chief minister of the cathedral. He was no less eminent for his mental culture than for his piety. He was a preacher and writer who had the courage of his convictions, and this quality is notably manifest in the hymn by him found in this collection. He died August 11, 1722.
