Hildegard of Bingen, O.S.B.(1098 – 17 September 1179), was a German Benedictine abbess, writer, composer, philosopher, Christian mystic, visionary, and polymath. She is considered the founder of scientific natural history in Germany.
Hildegard was elected magistra [mother] by her fellow nuns in 1136; she founded the monasteries of Rupertsberg in 1150 and Eibingen in 1165. One of her works as a composer, the Ordo Virtutum [order/way of virtue], is an early example of liturgical drama and arguably the oldest surviving morality play. She wrote theological, botanical, and medicinal texts, as well as letters, liturgical songs, and poems, while supervising miniature illuminations in the Rupertsberg manuscript of her first work.
Although the history of her formal consideration for sanctity is complicated, she has been recognized as a saint by branches of the Roman Catholic Church for centuries. On 7 October 2012, Pope Benedict XVI named her a Doctor of the Church.
