Johannes Tautz
Together with a young friend, Thomas Meyer, he visited the daughter of Walter Johannes Stein, Clarissa Johanna Muller, in Ireland where she was living in order to look through her father's literary estate. They found the typscript of Stein's dissertation annotated by Rudolf Steiner, letters and meditations of Steiner for Stein, his mother and for his brother, who fell in a mysterious manner in World War I. Letters and notes of Ludwig Polzer-Hoditz, Eliza von Moltke, Ita Wegman, D.N Dunlop and many other personalities were discovered and formed the basis of Tautz's biography of Stein in 1989
