Johanne Agerskov

Together with her husband, Michael Agerskov, she was responsible for the ethico-religious, philosophical, and pseudo-scientific book, Toward the Light (in Danish, Vandrer mod Lyset!

During the first decade of the twentieth century, Michael became interested in spiritual phenomena, and persuaded his wife to participate in séances, even though she was skeptical in the beginning.

Soon Johanne came to believe that the spirits of the transcendental world had called upon her, and had given her the message that she was a medium, and that before her birth she had promised to be instrumental in bringing eternal truths to mankind.

That resulted in the publication of the book, Toward the Light, which Agerskov called "a message to mankind from the transcendental world", and which she and her husband sent out to all the bishops and sixty ministers of the Danish national church.

The Agerskovs made great efforts to that end, through correspondence and by opening their home to anybody who wanted to see them about Toward the Light; but there was little public interest in the book, and the expected reformation did not take place.

In 1924 a Danish professor asserted that Malling-Hansen was not the inventor of the Hansen Writing Ball, and Agerskov undertook a thorough investigation of the facts, together with her sister, Engelke Wiberg.
