St. Hildegard of Bingen

St. Hildegard of Bingen was the abbess of a German Benedictine convent and an extraordinarily accomplished woman. Hildegard experienced a series of mystical visions that she documented, and she also studied and wrote about biology, botany and medicine. She was a talented poet and music composer as well, and a prolific letter-writer. Many people, including popes and kings, sought her out for spiritual and political advice. Hildegard died in 1179 at the ripe old age of 81, and left behind a treasure-trove of illuminated manuscripts, scholarly writings and songs. Pope Benedict XVI canonized her in the spring of 2012, and a few months later declared her a Doctor of the Church.
