Question: When was the brand opened in Alexandre Bennigsen's birthplace?

full_context: Document 1: Telecommunications in India: Telecommunications in India began with the introduction of the telegraph. The Indian postal and telecom sectors are one of the worlds oldest. In 1850, the first experimental electric telegraph line was started between Calcutta and Diamond Harbour. In 1851, it was opened for the use of the British East India Company. The Posts and Telegraphs department occupied a small corner of the Public Works Department, at that time.
Document 2: Pavel Schilling: Schilling's first electromagnetic telegraph cable line was set up in his apartment in St Petersburg. In 1832, Schilling demonstrated the long-distance transmission of signals by positioning two telegraphs of his invention—his device was said to be the first electromagnetic telegraph in the world—in two different rooms of his apartment. Schilling was the first to put into practice the idea of a binary system of signal transmissions. Schilling's contributions to electrical telegraphy were named an IEEE Milestone in 2009.
Document 3: Siemens: Siemens & Halske was founded by Werner von Siemens and Johann Georg Halske on 12 October 1847. Based on the telegraph, their invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on 12 October.In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850, the founder's younger brother, Carl Wilhelm Siemens, later Sir William Siemens, started to represent the company in London. The London agency became a branch office in 1858. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl Heinrich von Siemens, opened in St Petersburg, Russia. In 1867, Siemens completed the monumental Indo-European telegraph line stretching over 11,000 km from London to Calcutta.
Document 4: Transatlantic telegraph cable: William Cooke and Charles Wheatstone introduced their working telegraph in 1839. As early as 1840 Samuel F.B. Morse proclaimed his faith in the idea of a submarine line across the Atlantic Ocean. By 1850 a cable was run between England and France. That same year Bishop John T. Mullock, head of the Roman Catholic Church in Newfoundland, proposed a telegraph line through the forest from St. John's to Cape Ray, and cables across the Gulf of St. Lawrence from Cape Ray to Nova Scotia across the Cabot Strait.
Document 5: Alexandre Bennigsen: Bennigsen was born in St Petersburg in 1913. After the Bolshevik Revolution, his family left Russia for Estonia in 1919 and settled in Paris in 1924, where he studied at the Ecole des Langues Orientales.
Document 6: Elevator: The first electric elevator was built by Werner von Siemens in 1880 in Germany. The inventor Anton Freissler developed the ideas of von Siemens and built up a successful enterprise in Austria-Hungary. The safety and speed of electric elevators were significantly enhanced by Frank Sprague who added floor control, automatic elevators, acceleration control of cars, and safeties. His elevator ran faster and with larger loads than hydraulic or steam elevators, and 584 electric elevators were installed before Sprague sold his company to the Otis Elevator Company in 1895. Sprague also developed the idea and technology for multiple elevators in a single shaft.
Document 7: Kseniya Boguslavskaya: Born in St. Petersburg, she studied art in Paris from 1911 to 1913. She returned to St. Petersburg in 1913 and married Ivan Puni.

He also discovered the works of Rudolf Steiner. In 1920, Tomberg fled with his family to Tallinn in Estonia, where, searching for his mother who had left the house, he discovered her with her dog tied to a tree, both shot by Communist revolutionaries.

Document 11: Osip Senkovsky: Senkovsky was born into an old family of Polish szlachta. During his study in the University of Vilno he became fascinated with all things oriental. Having mastered the Arabic, Persian, Turkish, and Hebrew languages, he was assigned to the Russian mission in Constantinople, which occupation gave him ample opportunities to travel in Syria, Nubia, and Egypt.

Document 12: Sergey Oldenburg: Sergey Feodorovitch Oldenburg was born in Russia on 26 September 1863, in Byankino, Transbaikal Oblast. His father was ; his grandfather was a full general in the Imperial Russian Army. During the 1880s while at St. Petersburg University Oldenburg participated in the Scientific-Literary Association of Students, a brotherhood which shared liberal and radical ideals. Here he met Aleksandr Ulyanov as they were both in the inner circle of this organisation. Ulyanov dropped out of the inner circle when he started to plan an assassination attempt on the life of emperor Alexander III. The attempt failed, and following the execution of Ulyanov in 1887, his brother, Vladimir Lenin visited Oldenburg in St Petersburg in 1891. Oldenburg had just returned from a two-year trip to London, Paris, and Cambridge.
Document 13: Vladimir Lenin: Born to a moderately prosperous middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Russian Empire's Tsarist government, he devoted the following years to a law degree. He moved to Saint Petersburg in 1893 and became a senior Marxist activist. In 1897, he was arrested for sedition and exiled to Shushenskoye for three years, where he married Nadezhda Krupskaya. After his exile, he moved to Western Europe, where he became a prominent theorist in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1903, he took a key role in a RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Encouraging insurrection during Russia's failed Revolution of 1905, he later campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which as a Marxist he believed would cause the overthrow of capitalism and its replacement with socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia to play a leading role in the October Revolution, in which the Bolsheviks overthrew the new regime.
Document 14: Dan Petrașincu: He was born in Odessa from an Italian father and a Romanian mother. In the aftermath of the Russian Revolution, when he was ten years old, the family fled to Romania, where he went to high school in Râmnicu Sărat and Bucharest.
Document 15: Alexander Graham Bell: The value of the Bell patent was acknowledged throughout the world, and patent applications were made in most major countries, but when Bell had delayed the German patent application, the electrical firm of Siemens & Halske (S&H) managed to set up a rival manufacturer of Bell telephones under their own patent. The Siemens company produced near-identical copies of the Bell telephone without having to pay royalties. The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. The strain put on Bell by his constant appearances in court, necessitated by the legal battles, eventually resulted in his resignation from the company.[N 19]
