full_context: Document 1: Carl Heinrich von Siemens: Carl Heinrich von Siemens (often just Carl von Siemens) (3 March 1829 in Menzendorf, Mecklenburg – 21 March 1906 in Menton, France) was a German entrepreneur, a child (of fourteen) of a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. He is a brother of Ernst Werner von Siemens and William Siemens, sons of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839). They had two more brothers, Hans Siemens (1818–1867) and Friedrich August Siemens (December 8, 1828-May 24, 1904), married and father to Friedrich Carl Siemens (6 January 1877 – 25 June 1952 in Berlin), married on May 22, 1920 in Berlin to Melanie Bertha Gräfin Yorck von Wartenburg (1 February 1899 in Klein Oels – 15 May 1950 in Berlin) (the parents of Heinrich Werner Andreas Siemens (born 28 September 1921) Annabel Siemens (born 3 May 1923), Daniela Siemens (born 31 July 1926) and Peter Siemens (born 8 November 1928).
Document 2: 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 3: Pavel Gusterin: Pavel Gusterin is a graduate of the Tver State University (Department of History; 1994), the Institute of Asian and African Countries at the Moscow State University named after Mikhail Vasilyevich Lomonosov (Department of Arab Studies; 2001), and the Diplomatic Academy of the Ministry of Foreign Affairs of the Russian Federation (Department of International relations; 2011).
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: Vikentii Trofimov: In 1899 Vikentii Trofimov graduated from Stroganov Central College of Technical Drawing (now Stroganov Moscow State University of Arts and Industry, informally named Stroganovka). He and his friend Ignaty Nivinsky were both recommended for the gold medal. As there was only one gold medal, the two friends instead were encouraged to travel and teach abroad, and they agreed. A little later Trofimov married Ignaty's sister Vera, a very talented person with abilities in theatre. Trofimov continued his painting education in the private school of Zhukovsky and Halyavin, and travelled extensively in Europe.
Document 6: Zivar bey Ahmadbeyov: In 1902, Zivar bey Ahmadbeyov graduated from Saint-Petersburg State University of Architecture and Civil Engineering. From this year to 1917, Ahmadbeyov worked as an architect in Baku Governorate, then in Baku City Council. After the establishment of the Azerbaijan Democratic Republic, Ahmadbeyov became the chief architect of Baku and held this post until 1922. Two of the largest mosques in Baku, the Baku-Blue Mosque and Taza Pir Mosque were constructed according to the projects of Ahmadbeyov. Murtuza Mukhtarov Mosque, which was constructed according to Ahmadbeyov's project in the municipality of Amirjan in Baku, was added to the list of historical monuments of UNESCO. Besides that, Ahmadbeyov is the architect of a lot of houses in Vladikavkaz and the building of the Ophthalmology Institute in Baku.
Document 7: 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 8: Vasily Radlov: Working as a schoolteacher in Barnaul, Radlov became interested in the native peoples of Siberia and published his ethnographic findings in the influential monograph "From Siberia" (1884). From 1866 to 1907, he translated and released a number of monuments of Turkic folklore. Most importantly, he was the first to publish the Orhon inscriptions. Four volumes of his comparative dictionary of Turkic languages followed in 1893 to 1911. Radlov helped establish the Russian Museum of Ethnography and was in charge of the Asiatic Museum in St. Petersburg from 1884 to 1894.
Document 9: History of mobile phones: Before the devices existed that are now referred to as mobile phones or cell phones, there were some precursors. In 1908, a Professor Albert Jahnke and the Oakland Transcontinental Aerial Telephone and Power Company claimed to have developed a wireless telephone. They were accused of fraud and the charge was then dropped, but they do not seem to have proceeded with production. Beginning in 1918, the German railroad system tested wireless telephony on military trains between Berlin and Zossen. In 1924, public trials started with telephone connection on trains between Berlin and Hamburg. In 1925, the company Zugtelephonie AG was founded to supply train telephony equipment and, in 1926, telephone service in trains of the Deutsche Reichsbahn and the German mail service on the route between Hamburg and Berlin was approved and offered to first - class travelers.
Document 10: Boris Turayev: After graduating from the University of St Petersburg (1891) Turayev studied under Gaston Maspero and Adolf Erman and worked in museums of Berlin, Paris and London. Since 1896, he delivered lectures at the University of St Petersburg. He was an ordinary professor of this university since 1911. After the establishment of the Moscow Museum of Fine Arts, Turayev persuaded Vladimir Golenishchev to sell his collection of ancient Egyptian statuary and curiosities to the museum. For a time he lived in the museum building, preparing the collection for exhibition. His own collection of Egyptian antiquities went to the State Hermitage.
Document 11: 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 12: 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 13: Zaid Orudzhev: Zaid Orudzhev was born in Baku, entered the Faculty of Philosophy at Lomonosov Moscow State University in the early 1950s, graduating in 1955. For the next 12 years, he taught at a number of educational institutions back in Baku (mainly at the state university), during which time he was awarded a doctorate for his thesis on “The problems of dialectical logic in the economic research of Karl Marx”. In 1967-1969 he founded and was at the head of the department of philosophy at the Moscow Institute of Electronic Technology.
Document 14: 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 15: 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.
