[1] Sedelmeyer moved from Vienna to Paris in 1866 and chose to set up a small gallery at 54 Rue du Faubourg-Montmartre, in close proximity to the renowned Hôtel Drouot auction house.

[6] Galerie Sedelmeyer held an exhibition of James Tissot's series "La Femme à Paris" (The Parisian Woman) from 19 April to 15 June 1885.

The gallery exhibition was made up of two parts, the modern artists and the Old Masters, featuring works by Brožík, Charles-François Daubigny, Narcisse Virgilio Díaz, Vojtěch Hynais, Eugen Jettel, Tito Lessi, Munkácsy, and more.

[10] On 1 July 1889, the gallery was set to auction a collection of modern and Old Masters' paintings, watercolors, and drawings, which had been curated by the French art collector Eugène Secrétan.

[11] In 1890, the 'Catalogue of the Celebrated Collection of Paintings by Modern and Ancient Masters Formed by the Late Senator Prosper Crabbe of Brussels' was published by Galerie Sedelmeyer.

[3] The modern section of the collection featured works by Jean-Baptiste-Camille Corot, Alexandre-Gabriel Decamps, Eugène Delacroix, Diaz, Jules Dupré, Eugène Fromentin, Théodore Géricault, Jan August Hendrik Leys, Ernest Meissonier, Jean-François Millet, Théodore Rousseau, Alfred and Joseph Stevens, Constant Troyon, and Florent Willems.

[14] That year, the gallery initiated the publication of illustrated catalogues, each detailing a set of 100 paintings by old masters from the Dutch, Flemish, Italian, French, and English schools in their possession.

[18] The gallery displayed an altarpiece titled "Pala Colonna" by the Italian painter Raphael, which sold to American financier and art collector J. P. Morgan for over 2 million francs in April 1901.
