Daniel,
On the origins of the Metro station names, they are named
after historical sites (battles) eg., Danube, Wagram, Iena, Solferino, Austerlitz, Alma, Bir Hakeim,
Stalingrad, Ourcq, Liege, Alesia; famous generals, eg.,Kleber, Cambronne, Hoche, Galleni, Foch, Bolivar, Caulaincourt,Ch. de Gaulle; writers, scientists, politicians, (Louis Blanc, Voltaire, Gambetta, Mirabeau, Victor Hugo, E.Zola, Pasteur, A. Dumas, FD Roosevelt, Garibaldi, Juares,)
Some of the names are from the Napoleonic era, eg, Campo Formio, the treaty of.
I hope this helps a little in finding out the origins of the stations.
