Rudolf Steiner found the spiritual science of anthroposophy and the many practical disciplines that arose from it. Eventually, he would write his Autobiography, although its composition would be interrupted by his unexpected death. This volume is an essential complement to Steiner's unfinished autobiography. It gathers a wealth of personal testimonies, lectures, résumés, notebook entries, a questionnaire, and biographical notes written for Édouard Schuré — much of which has not been previously published in English.
