Born in Holland in 1893, Zeylmans van Emmichoven was one of the original pioneers of anthroposophy, the science of spirit established by Rudolf Steiner. As General Secretary of the Anthroposophical Society in the Netherlands, he worked closely with Steiner. A medical doctor and founder of the Rudolf Steiner Clinic in Scheveningen, he also conducted important research into the influence of colours, the psychology of peoples and nations, and individual human psychology. Emanuel Zeylmans' biography of his father draws on some beautifully written and moving autobiographical extracts as well as numerous other first-hand source materials. He traces Zeylmans' remarkable life from his upbringing in Holland and his first contact with Rudolf Steiner to his later attendance at the momentous Christmas Foundation Meeting and his many travels around the world to further anthroposophy. He examines the spiritual conflicts in which Zeylmans became embroiled, his life during the war years, and his innovative work in many fields. The author also catalogues Zeylmans' written works, and gives a full chronology of his life. Willem Zeylmans van Emmichoven is a compelling documentation of a leading figure connected with Rudolf Steiner. It brings to life the context of his biography - an exciting and yet difficult time in the development of new spiritual ideas - and the vibrant individuals around him. Zeylmans is portrayed as a warm, dynamic and fascinating individual, with enormous interest in people from widely differing cultures and backgrounds. A real 'world citizen', he recognized that every nation has its own particular task and importance.
