↑ Steiner's autobiography gives his date of birth as ngày 27 tháng 2 năm 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 the 25th of February 1861. Two days later I was baptized." See Christoph Lindenberg, Rudolf Steiner, Rowohlt 1992, ISBN 3-499-50500-2, p. 8. In 2009 new documentation appeared supporting a date of 27 Feb.: see Günter Aschoff, "Rudolf Steiners Geburtstag am 27. Februar 1861 - Neue Dokumente", Das Goetheanum 2009/9, pp. 3ff
