There is not much out there by Katie Luther, in fact hardly anything at all. What we come to know of her we come to know through her husband Martin Luther's letters. She was an ex nun who became a famous yet hated man's wife, a mother, a businesswoman, she brewed her own beer, and she did what had to be done. Although it was hard, after her husband died it became even more difficult. Life was not easy in the 16th century for a woman like Katie.
