Question: When was the brand opened in Alexander Koenig's birthplace?

full_context: Document 1: 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 2: 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 3: Alexander Koenig: Koenig was born at St Petersburg, Russia where his father was a successful merchant. He grew up in Bonn. Koenig became interested in natural history at an early age and started to collect specimens.
Document 4: 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]
Document 5: 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 6: 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 7: Georg Ossian Sars: Georg Ossian Sars was born on 20 April 1837 in Kinn, Norway (now part of Flora), the son of Pastor Michael Sars and Maren Sars; the historian Ernst Sars was his elder brother, and the singer Eva Nansen was his younger sister. He grew up in Manger, Hordaland, where his father was the local priest. He studied from 1852 to 1854 at Bergen Cathedral School, from 1854 at Christiania Cathedral School, and joined the university at Christiana (now the University of Oslo) in 1857. He indulged his interest in natural history while studying medicine; having collected water fleas in local lakes with Wilhelm Lilljeborg's works, he discovered new species, and this resulted in his first scientific publication. Georg Ossian Sars had a good memory and excellent drawing skills, and illustrated some of his father's zoological works.
Document 8: Alfred Nobel: Born in Stockholm, Alfred Nobel was the third son of Immanuel Nobel (1801–1872), an inventor and engineer, and Carolina Andriette (Ahlsell) Nobel (1805–1889). The couple married in 1827 and had eight children. The family was impoverished, and only Alfred and his three brothers survived past childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702), and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age. Alfred Nobel's interest in technology was inherited from his father, an alumnus of Royal Institute of Technology in Stockholm.
Document 9: 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 10: Abraham Roentgen: Roentgen was born in Mülheim am Rhein, Germany. He learned cabinet making from his father. At age 20, he traveled to Den Haag, Rotterdam and Amsterdam, learning from established cabinet makers.
Document 11: Nicolai Ivanovich Andrusov: He was born in Odessa, then a part of Russia. He studied geology and zoology at the Novorossia University in Odessa. He then traveled across Russia and central Europe to collect fossil specimens.
Document 12: Andreas von Tuhr: Von Tuhr was born in St Petersburg to a Russian family of German ethnicity on 14 February 1864. When he was still a child, they moved to Germany. He studied at the universities of Heidelberg, Leipzig and Strasbourg and was much influenced by Bernhard Windscheid and Ernst Bekker.
Document 13: 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 14: Søren Kierkegaard: Kierkegaard was born to an affluent family in Copenhagen. His mother, Ane Sørensdatter Lund Kierkegaard, had served as a maid in the household before marrying his father, Michael Pedersen Kierkegaard. She was an unassuming figure: quiet, plain, and not formally educated, but Henriette Lund, her granddaughter, wrote that she "wielded the sceptre with joy and protected [Søren and Peter] like a hen protecting her chicks". She also wielded influence on her children so that later Peter said that his brother preserved many of their mother's words in his writings. His father, on the other hand, was a well-to-do wool merchant from Jutland. He was a "very stern man, to all appearances dry and prosaic, but under his 'rustic cloak' demeanor he concealed an active imagination which not even his great age could blunt". He was also interested in philosophy and often hosted intellectuals at his home. The young Kierkegaard read the philosophy of Christian Wolff. He also preferred the comedies of Ludvig Holberg, the writings of Georg Johann Hamann, Gotthold Ephraim Lessing, Edward Young, and Plato, especially those referring to Socrates.
