Following Elisabeth Förster-Nietzsche's death, it became known within the Archiv that she had forged some documents and anecdotes relating to her brother Friedrich; this fact was not made public, however. In fact, Oehler seems to have publicly renounced only one of Förster-Nietzsche's legends: in 1937, he showed in an article that the Nietzsche family did not descend from Polish nobility, as was claimed by both Elisabeth and Friedrich Nietzsche himself on occasion. Oehler's conclusion is accepted as correct today, and was very much approved by Nazi ideology.
