^ abSteiner's autobiography gives his date of birth as 27 February 1861. However, there is an undated autobiographical fragment written by Steiner, referred to in a footnote in his autobiography in German (GA 28), that says, "My birth fell on 25 February 1861. Two days later I was baptized." See Christoph Lindenberg, Rudolf Steiner, Rowohlt 1992, ISBN3-499-50500-2, p. 8.
