He was active as a pacifist in the First World War and did social work with the Quakers, in particular with the Friends’ War Relief organisation in Poland. He worked for the rest of his life for Anthroposophy with a special interest in the scientific side as well as developing the social aspects. He interpreted Steiner’s lectures in England and later translated many of them into English. He discovered how to describe Steiner’s findings about negative space in geometric terms. He worked particularly with projective geometry and the application of path curves.
