André Amédée Gustave Slomszynski, Słomczyński or Slomczynski, known professionally as Slom (9 July 1844[1] – 27 December 1909[2]), was a French painter, engraver, illustrator and cartographer of Polish origin.
After the Bloody Week (la semaine sanglante) in May 1871, he was sentenced to death by the Versailles army who accused him of inciting the Gardes nationaux to execute the three hostage gendarmes.
He settled in Lausanne and became the companion in misfortune of Eugène Protot, former minister of justice, who was similarly in exile, and of Maxime Vuillaume.
He gave evening classes on "imitative and ornamental drawing" (dessin d'imitation et d'ornementation) in Lausanne and then worked at Vevey with Élisée Reclus, for whom he illustrated several volumes of the Nouvelle Géographie universelle.
Under the pseudonym "Slom", he signed many drawings which were published in connection with the Exposition universelle of 1889 the Eiffel Tower, the 1931 Paris Colonial Exhibition at the Esplanade des Invalides and the entrance gate to the Quai d'Orsay.
