Question: What year did the Belgian architect die? Passage 1:He returned to the factory in Kamianske during the Russian Revolution of 1905. He again joined the volunteer fire brigade. He returned to Vilnius in 1911 and organized a fire brigade in Šnipiškės in 1914. Semashko rallied the men into a militia to protect the city from hooligans and fires when the Russian Imperial Army abandoned the city during the Great Retreat in mid 1915. He became city's fire chief (brandmajor) and commanded both local and German Ober Ost firefighters during fire. At the same time, he turned away from Polish political activists towards Belarusian and Lithuanian causes. He was a contributor to the Belarusian newspaper Homan and was elected to the Rada of the Belarusian Democratic Republic in January 1918. He participated in the declaration of independence of the Belarusian People's Republic and drafted plans for establishing a Belarusian university, named after Adam Mickiewicz, in Minsk. On 23 April 1918, he participated in discussions with the Council of Lithuania regarding the territory of Lithuania and Belarus after the war and ideas on resurrecting the old Grand Duchy of Lithuania. 
 Passage 2:The Franco-German art dealer and publisher Siegfried Bing played a key role in publicizing the style. In 1891, he founded a magazine devoted to the art of Japan, which helped publicize Japonism in Europe. In 1892, he organized an exhibit of seven artists, among them Pierre Bonnard, Félix Vallotton, Édouard Vuillard, Toulouse-Lautrec and Eugène Grasset, which included both modern painting and decorative work. This exhibition was shown at the Société nationale des beaux-arts in 1895. In the same year, Bing opened a new gallery at 22 rue de Provence in Paris, the Maison de l'Art Nouveau, devoted to new works in both the fine and decorative arts. The interior and furniture of the gallery were designed by the Belgian architect Henry Van de Velde, one of the pioneers of Art Nouveau architecture. The Maison de l'Art Nouveau showed paintings by Georges Seurat, Paul Signac and Toulouse-Lautrec, glass from Louis Comfort Tiffany and Emile Gallé, jewellery by René Lalique, and posters by Aubrey Beardsley. The works shown there were not at all uniform in style. Bing wrote in 1902, "Art Nouveau, at the time of its creation, did not aspire in any way to have the honor of becoming a generic term. It was simply the name of a house opened as a rallying point for all the young and ardent artists impatient to show the modernity of their tendencies."
