Baltasar Hidalgo de Cisneros
The news of the fall of the Junta of Seville reached Buenos Aires in May 1810. With both the king of Spain and the Junta removed of power, many people thought that Cisneros had no legitimacy to govern, starting the May Revolution. Cisneros tried to calm down the population, to no avail. He called the commanders of the local armies and requested their support, but they denied it. Cisneros was ultimately forced to allow an open cabildo, which would discuss what to do. Although those meetings were usually composed of the wealthiest population, the army and a group of rioters plotted to prevent the entry of many wealthy people and allow common people instead.
Gaston Diehl
In October 1943, during the Nazi Occupation, Diehl founded the May Salon in Paris in a café on the Palais Royal, in opposition to the ideology of Nazism and its condemnation of degenerate art. Its other founder-members were Henri-Georges Adam, Emmanuel Auricoste, Lucien Coutaud, Robert Couturier, Jacques Despierre, Marcel Gili, Leon Gischia, Francis Gruber, René Iché, Jean Le Moal, Alfred Manessier, André Marchand, Edouard Pignon, Gustave Singier, Claude Venard and Roger Vieillard. Several of them (Coutaud, Gischia, Iché, Le Moal, Manessier, Marchand, Pignon, Singier) had in 1941 participated in the exhibition of Twenty young painters of French tradition. The first May Salon took place at the Galerie Pierre Maurs from May 29 to June 29, 1945.
