Moberly–Jourdain incident

The Moberly–Jourdain incident (also the Ghosts of Petit Trianon or Versailles, French: les fantômes du Trianon / les fantômes de Versailles) is a claim of time travel and hauntings made by Charlotte Anne Moberly (1846–1937) and Eleanor Jourdain (1863–1924). In 1911, Moberly and Jourdain published a book entitled An Adventure under the names of "Elizabeth Morison" and "Frances Lamont".
