Jakob Böhme (; 1575 – November 17, 1624) was a German Christian mystic and theologian. He is considered an original thinker within the Lutheran tradition, and his first book, commonly known as Aurora, caused a great scandal. In contemporary English, his name may be spelled Jacob Boehme; in seventeenth-century England it was also spelled Behmen, approximating the contemporary English pronunciation of the German Böhme.
