Hildegard of Bingen  (German: Hildegard von Bingen; Latin: Hildegardis Bingensis; 1098 - 17 September 1179), also known as Saint Hildegard and Sibyl of the Rhine, was a German Benedictine abbess, writer, composer, philosopher, Christian mystic, visionary, and polymath. She is considered to be the founder of scientific natural history in Germany. Hildegard was elected magistra 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, is an early example of liturgical drama and arguably the oldest surviving morality play.

Perhaps because of Hildegard's visions, or as a method of political positioning (or both), Hildegard's parents offered her as an oblate to the Benedictine monastery at the Disibodenberg, which had been recently reformed in the Palatinate Forest. The date of Hildegard's enclosure at the monastery is the subject of debate. Her Vita says she was professed with an older woman, Jutta, the daughter of Count Stephan II of Sponheim, at the age of eight. However, Jutta's date of enclosure is known to have been in 1112, when Hildegard would have been fourteen. Their vows were received by Bishop Otto Bamberg on All Saints' Day, 1112. Some scholars speculate that Hildegard was placed in the care of Jutta at the age of eight, and the two women were then enclosed together six years later.  In any case, Hildegard and Jutta were enclosed together at the Disibodenberg, and formed the core of a growing community of women attached to the male monastery. Jutta was also a visionary and thus attracted many followers who came to visit her at the cloister. Hildegard tells us that Jutta taught her to read and write, but that she was unlearned and therefore incapable of teaching Hildegard sound biblical interpretation. The written record of the Life of Jutta indicates that Hildegard probably assisted her in reciting the psalms, working in the garden and other handiwork, and tending to the sick. This might have been a time when Hildegard learned how to play the ten-stringed psaltery. Volmar, a frequent visitor, may have taught Hildegard simple psalm notation. The time she studied music could have been the beginning of the compositions she would later create.  Upon Jutta's death in 1136, Hildegard was unanimously elected as magistra of the community by her fellow nuns. Abbot Kuno of Disibodenberg asked Hildegard to be Prioress, which would be under his authority. Hildegard, however, wanted more independence for herself and her nuns, and asked Abbot Kuno to allow them to move to Rupertsberg. This was to be a move towards poverty, from a stone complex that was well established to a temporary dwelling place. When the abbot declined Hildegard's proposition, Hildegard went over his head and received the approval of Archbishop Henry I of Mainz. Abbot Kuno did not relent until Hildegard was stricken by an illness that kept her paralyzed and unable to move from her bed, an event that she attributed to God's unhappiness at her not following his orders to move her nuns to Rupertsberg. It was only when the Abbot himself could not move Hildegard that he decided to grant the nuns their own monastery. Hildegard and about twenty nuns thus moved to the St. Rupertsberg monastery in 1150, where Volmar served as provost, as well as Hildegard's confessor and scribe. In 1165 Hildegard founded a second monastery for her nuns at Eibingen.
