 Examples of literary executors include Sir Edward Marsh for Rupert Brooke, Robert Baldwin Ross for Oscar Wilde, Robert Hayward Barlow for H. P. Lovecraft, Rush Rhees, G. H. von Wright and G. E. M. Anscombe for Ludwig Wittgenstein, Otto Nathan for Albert Einstein, Regine Olsen for Søren Kierkegaard and Paul Williams for Philip K. Dick.A particularly notorious example is Elisabeth Förster-Nietzsche for Friedrich Nietzsche, as she resorted to fraud to make her brother's "Nachlass" more compatible with Nazi ideology.An exceptionally productive example is that of Rudolf Steiner.
