Ita Wegman, born in 1876 to a Dutch family living in Indonesia, first met Rudolf Steiner in Berlin in 1902 when she was 26 years old. She studied medicine at the University of Zurich and in 1917, following Steiner's indications, developed a treatment for cancer using mistletoe. In 1921 she founded the first anthroposophical medical clinic, in Arlesheim, Switzerland, followed in 1922 by the Sonnenhof home for children with special needs.

Karl König first met Wegman in 1927, and she quickly recognized his great potential, as well as his weaknesses. She invited him to work at the Arlesheim clinic as her assistant, and encouraged and advised him in his medical work.

This book includes the complete correspondence between König and Wegman.
