Élisabeth de Gramont had grown up among the highest aristocracy; when she was a child, according to Janet Flanner, "peasants on her farm... begged her not to clean her shoes before entering their houses". She looked back on this lost world of wealth and privilege with little regret, and became known as the "red duchess" for her support of socialism and feminism.She was a close friend, and sometimes critic of writer Marcel Proust, whom she first met in 1903.

Charles-François-Prosper Guérin (1875 in Sens – 1939) was a French post-impressionist painter.
Guérin studied with Gustave Moreau in the l'École des Beaux Arts à Paris, and had one exhibition at the Grafton Galleries in 1910; in a review Huntly Carter wrote of his "daring extravagance" and that he "show[ed] how the strongest primary colours can be used without crudity, and whose work has a decorative value which the average muddy and colourless work of our day does not possess".Guérin attained some historic notoriety for sitting on the jury of the Salon d'Automne of 1908, which rejected almost all of the paintings of Georges Braque. The other jury members were Henri Matisse, Georges Rouault, and Albert Marquet, all of whom had also been students of Moreau.: 254 p.  The jury's action caused Braque—who had been a great success the year before—to withdraw completely from the Salon. Braque subsequently entered into an exclusive contract with the dealer Daniel-Henry Kahnweiler requiring him (and Picasso) to avoid salons, during which time Braque and Picasso developed cubism.
Guérin was teaching at the Académie de La Palette in 1907 when Henri Hayden studied there and at the Académie Moderne in 1913 when Blanche Lazzell enrolled there, as well as at the Académie de la Grande Chaumière.

On 23 January 1941, he was made a member of the National Council of Vichy France. A few months after the liberation of France in mid-1944, he was elected to the Académie française, taking the vacant seat of Gabriel Hanotaux (who had been elected in 1897).

Paul Pfeiffer (21 April 1875 – 4 March 1951) was an influential German chemist. He received his Ph.D. at the University of Zurich, studying under Alfred Werner, the "father of coordination chemistry". His thesis, submitted in 1898, dealt with adducts of tin halides.
Pfeiffer was considered Werner's most successful student and became Werner's assistant until, due to a dispute with his mentor, he left first for Rostock, then Karlsruhe, and finally Bonn. At Bonn, where he had studied as an undergraduate, he occupied Kekulé's chair.
Pfeiffer's work spanned many themes. The Pfeiffer effect, which involves interactions between chiral solutes, is named after his discoveries. His group first made the salen ligands, which gave the first artificial oxygen carriers. He recognized that crystals, e.g. of zinc sulfide, are large molecules.
