Document 2: 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 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: World War II: When civil war broke out in Spain, Hitler and Mussolini lent military support to the Nationalist rebels, led by General Francisco Franco.  Italy supported the Nationalist to a greater extent than  National-Socialist did: altogether Mussolini sent to Spain more than 70,000 ground troops and 6,000 aviation personnel, as well as about 720 aircraft. The Soviet Union supported the existing government, the Spanish Republic. Over 30,000 foreign volunteers, known as the International Brigades, also fought against the Nationalists. Both Germany and the Soviet Union used this proxy war as an opportunity to test in combat their most advanced weapons and tactics. The Nationalists won the civil war in April 1939; Franco, now dictator, remained officially neutral during World War II but generally favoured the Axis. His greatest collaboration with Germany was the sending of volunteers to fight on the Eastern Front.
Document 5: 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 6: Vladimir Ćopić: Vladimir "Senjko" Ćopić (8 March 1891 – 19 April 1939) was a Croatian communist and leader of the Communist Party of Yugoslavia from April 1919 to August 1920. During the Spanish Civil War, in the period from 1937 to mid-1938, he was the commander of the XV International Brigade.
Document 7: Spanish Civil War: The Spanish Civil War (Spanish: Guerra Civil Española), widely known in Spain simply as The Civil War (Spanish: La Guerra Civil) or The War (Spanish: La Guerra), took place from 1936 to 1939. The Republicans, who were loyal to the democratic, left - leaning and relatively urban Second Spanish Republic, in an alliance of convenience with the Anarchists and Communists, fought against the Nationalists, a Falangist, Carlist, Catholic, and largely aristocratic conservative group led by General Francisco Franco. The war has often been portrayed as a struggle between democracy and fascism, particularly due to the political climate and timing surrounding it, but it can more accurately be described as a struggle between leftist revolution and rightist counter-revolution similar to the Finnish Civil War, the Russian Civil War, and the wars fought over the formation of the Hungarian and Slovak Soviet republics. In early 1939, the Nationalists won, and Franco ruled over all of Spain until his death in November 1975.
Document 8: 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 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: 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 11: 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 12: Vladimir Kurdyumov: Kurdyumov served in the Red Army since 1918 in World War I and the Russian Civil War. He graduated from the Frunze Military Academy in 1925 and served as military attaché in the Baltic countries. From August 1931 Kurdyumov was a commander and commissar of the 25th Rifle Division.
Document 13: The Times: Kim Philby, a Soviet double agent, was a correspondent for the newspaper in Spain during the Spanish Civil War of the late 1930s. Philby was admired for his courage in obtaining high-quality reporting from the front lines of the bloody conflict. He later joined MI6 during World War II, was promoted into senior positions after the war ended, then eventually defected to the Soviet Union in 1963.
Document 14: Georges Kopp: Georges Kopp, (St Petersburg, Russia 1902 – Marseilles, France 15 July 1951) was an engineer who had lived in Belgium for about 25 years and volunteered to fight for the Republicans in the Spanish Civil War, rising to become commander of the 3rd Regiment, Lenin Division, a militia unit belonging to the Workers' Party of Marxist Unification (POUM) which saw active service on the Aragon front, and was later incorporated into the regular army as the 29th Division of the Republican government's Popular Army. Kopp rose to become captain in the general staff of the 45th Mixed Brigade of the Spanish Republican Army.
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]
