Charlotte von Kirschbaum (June 25, 1899 – July 24, 1975) was a German theologian, and assisted Karl Barth in writing the Church Dogmatics. Charlotte von Kirschbaum was born in Ingolstadt. In 1916 her father died in the war, which inspired her to be trained as a nurse. In 1924 she met Karl Barth, and initially became his pupil and later contributed to all of Karl Barth's academic publications. Historians have discussed at length the romantic relationship with Barth and the possible impact on his theology. The letters between von Kirschbaum and Barth express "the deep, intense, and overwhelming love between these two human beings."
