Alexandre Florian Joseph, Count Colonna-Walewski (French pronunciation: [alɛksɑ̃dʁ kɔlɔna valɛvski]; Polish: Aleksander Florian Józef Colonna-Walewski; 4 May 1810 – 27 September 1868), also Count of the Empire, was a Polish and French politician and diplomat, the unacknowledged son of French emperor Napoleon I.

Élisabeth Félix (21 February 1821 – 3 January 1858), better known only as Mademoiselle or Madame Rachel or simply Rachel, was a French actress. She became a prominent figure in French society, and was the mistress of, among others, Napoleon III and Prince Napoléon, both nephews of Napoleon I, and of Alexandre Colonna-Walewski, the illegitimate son of Napoleon I. Efforts by newspapers to publish pictures of her on her deathbed led to the introduction of privacy rights into French law.
