January 7th in stamps Tesla, von Stephan, Reis, Ludwig III of Bavaria

Here are some events that happened on January 7th. It could be an event or a person that died or was born on that day

1831 Born: Heinrich von Stephan, German postman, founded the Universal Postal Union (d. 1897)

Ernst Heinrich Wilhelm von Stephan (Born Heinrich Stephan, January 7, 1831 – April 8, 1897) was a general post director for the German Empire who reorganized the German postal service. He was integral in the founding of the Universal Postal Union in 1874, and in 1877 introduced the telephone to Germany.

When Stephan began his work as a postal worker, Germany was divided into 17 independent states, each with its own separate policies and fees. He worked early on to establish a uniform postage rate throughout Germany, to facilitate easier mailing. His general goal of standardization and internationalization is evident in his work to combine the postal service with the telegraph service in Germany, and in his efforts to organize the International Postal Conference in Bern in 1874, in which the Universal Postal Union was established. He introduced the postcard (which he had initially suggested in 1865) to Germany after Chancellor Otto von Bismarck promoted him in 1870: the postcard came into widespread use in the subsequent Franco-Prussian War of 1870-71 as a method of communication between units in the field. He is also credited with having introduced the telephone to Germany.

1834 Born: Johann Philipp Reis, German physicist and academic, invented the Reis telephone (d. 1874)

Johann Philipp Reis (January 7, 1834 – January 14, 1874) was a self-taught German scientist and inventor. In 1861, he constructed the first make-and-break telephone, today called the Reis telephone.

In 1878, four years after his death and two years after Bell received his first telephone patent, European scientists dedicated a monument to Philip Reis as the inventor of the telephone.

Documents of 1947 in London's Science Museum later showed that after their technical adjustments, engineers from the British firm Standard Telephones and Cables (STC) found Reis' telephone dating from 1863 could transmit and "reproduce speech of good quality, but of low efficiency".

Sir Frank Gill, then chairman of STC, ordered the tests to be kept secret, as STC was then negotiating with AT&T, which had evolved from the Bell Telephone Company, created by Alexander Graham Bell. Professor Bell was generally accepted as having invented the telephone and Gill thought that evidence to the contrary might disrupt the ongoing negotiations.

1845 Born: Ludwig III of Bavaria (d. 1921)

Ludwig III (Ludwig Luitpold Josef Maria Aloys Alfried; 7 January 1845 – 18 October 1921) was the last king of Bavaria, reigning from 1913 to 1918. He served as regent and de facto head of state from 1912 to 1913, ruling for his cousin, Otto. After the Bavarian parliament passed a law allowing him to do so, Ludwig deposed Otto and assumed the throne himself. He led Bavaria into World War I, and lost his throne along with the other rulers of the German states at the end of the war.

On 7 November 1918, Ludwig fled from the Residenz Palace in Munich with his family and took up residence in Schloss Anif, near Salzburg, for what he hoped would be a temporary stay. He was the first of the monarchs in the German Empire to be deposed. The next day, the People's State of Bavaria was proclaimed.

On 12 November 1918, a day after the Armistice, Prime Minister Dandl went to Schloss Anif to see the King. Ludwig gave Dandl the Anif declaration (Anifer Erklärung) in which he released all government officials, soldiers and civil officers from their oath of loyalty to him. He also stated that as a result of recent events, he was "no longer in a position to lead the government." The declaration was published by the newly formed republican government of Kurt Eisner when Dandl returned to Munich the next day. Ludwig's declaration was not a statement of abdication, as Dandl had demanded. However, Eisner's government interpreted it as such and added a statement that Ludwig and his family were welcome to return to Bavaria as private citizens as long as they did not act against the "people's state." This statement effectively dethroned the Wittelsbachs and ended the family's 738-year rule over Bavaria.

1943 Died: Nikola Tesla, Serbian-American physicist and engineer (b. 1856)

Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Born and raised in the Austrian Empire, Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He emigrated in 1884 to the United States, where he would become a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company would eventually market.

Here are some events that happened on January 5th. It could be an event or a person that died or was born on that day


1524 Died: Marko Marulić, Croatian poet (b. 1450)

Marko Marulić Splićanin (18 August 1450 – 5 January 1524), was a Croatian poet and Renaissance humanist. He coined the term "psychology".

The Latin word psychologia was first used by the Croatian humanist and Latinist Marko Marulić in his book, Psichiologia de ratione animae humanae in the late 15th century or early 16th century. The earliest known reference to the word psychology in English was by Steven Blankaart in 1694 in The Physical Dictionary which refers to "Anatomy, which treats the Body, and Psychology, which treats of the Soul."

Very little is actually known about his life, and the few facts that have survived to this day are fairly unreliable. It is certain that he attended a school run by a humanist scholar Tideo Acciarini in his hometown. Having completed it, he is then speculated to have graduated law at the Padua University, after which he spent much of his life in his home town. Occasionally he visited Venice (to trade) and Rome (to celebrate the year 1500).

He lived for about two years in Nečujam on the island of Šolta. In Split, Marulić practised law, serving as a judge, examinator of notarial entries and executor of wills. Owing to his work, he became the most distinguished person of the humanist circle in Split.

He is regarded as the Croatian national poet and has been called the "crown of the Croatian medieval age" and the "father of the Croatian Renaissance".

1578 Died: Giulio Clovio, Dalmatian painter (b. 1498)

Giorgio Giulio Clovio or Juraj Julije Klović (1498 – 5 January 1578) was an illuminator, miniaturist, and painter born in the Kingdom of Croatia, who was mostly active in Renaissance Italy.  He is considered the greatest illuminator of the Italian High Renaissance, and arguably the last very notable artist in the long tradition of the illuminated manuscript, before some modern revivals.

1762 Died: Empress Elizabeth of Russia (b. 1709)

Elizabeth Petrovna (Russian: Елизаве́та (Елисаве́та) Петро́вна) (29 December 1709 – 5 January 1762), also known as Yelisaveta or Elizaveta, was the Empress of Russia from 1741 until her death. She led the country during the two major European conflicts of her time: the War of Austrian Succession (1740–48) and the Seven Years' War (1756–63).

Her domestic policies allowed the nobles to gain dominance in local government while shortening their terms of service to the state. She encouraged Mikhail Lomonosov's establishment of the University of Moscow and Ivan Shuvalov's foundation of the Imperial Academy of Arts in Saint Petersburg. She also spent exorbitant sums of money on the grandiose baroque projects of her favourite architect, Bartolomeo Rastrelli, particularly in Peterhof and Tsarskoye Selo. The Winter Palace and the Smolny Cathedral in Saint Petersburg are among the chief monuments of her reign. She remains one of the most popular Russian monarchs due to her strong opposition to Prussian policies and her decision not to execute a single person during her reign

1876 Born: Konrad Adenauer, German lawyer and politician, Chancellor of West Germany (d. 1967)

Konrad Hermann Joseph Adenauer (German: [ˈkɔnʁaːt ˈʔaːdənaʊɐ] (About this soundlisten); 5 January 1876 – 19 April 1967) was a German statesman who served as the first Chancellor of the Federal Republic of Germany (West Germany) from 1949 to 1963. He was co-founder and first leader of the Christian Democratic Union (CDU) (until 1966), a Christian Democratic party that under his leadership became one of the most influential parties in the country.

In the early years of the Federal Republic he switched focus from denazification to recovery and led his country from the ruins of World War II to becoming a productive and prosperous nation that forged close relations with France, the United Kingdom and the United States.  During his years in power, West Germany achieved democracy, stability, international respect and economic prosperity ("Wirtschaftswunder", German for "economic miracle").

Adenauer belied his age by his intense work habits and his uncanny political instinct. He displayed a strong dedication to a broad vision of market-based liberal democracy and anti-communism. A shrewd politician, Adenauer was deeply committed to a Western-oriented foreign policy and restoring the position of West Germany on the world stage. He worked to restore the West German economy from the destruction of World War II to a central position in Europe, presiding over the German Economic Miracle together with his Minister of Economics, Ludwig Erhard. He was a driving force in re-establishing national military forces (the Bundeswehr) in West Germany since 1955. Adenauer opposed rival East Germany and made his nation a member of NATO and a member of the Western Alliance.

Adenauer, who was Chancellor until age 87, was dubbed "Der Alte" ("the elder"). British politician and historian Roy Jenkins says he was "the oldest statesman ever to function in elected office." He remains the oldest head of government for a major country.

A devout Roman Catholic and member of the Catholic Centre Party, he was a leading politician in the Weimar Republic, serving as Mayor of Cologne (1917–1933) and as president of the Prussian State Council (1922–1933).

1933 Died: Calvin Coolidge, American lawyer and politician, 30th President of the United States (b. 1872)

Calvin Coolidge  (July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.

Coolidge restored public confidence in the White House after the scandals of his predecessor's administration, and left office with considerable popularity.  As a Coolidge biographer wrote: "He embodied the spirit and hopes of the middle class, could interpret their longings and express their opinions. That he did represent the genius of the average is the most convincing proof of his strength".

Scholars have ranked Coolidge in the lower half of those presidents that they have assessed. He is praised by advocates of smaller government and laissez-faire economics, while supporters of an active central government generally view him less favorably, though most praise his stalwart support of racial equality.

1970 Died: Max Born, German physicist and mathematician, Nobel Prize laureate (b. 1882)

Max Born (11 December 1882 – 5 January 1970) was a German-Jewish physicist and mathematician who was instrumental in the development of quantum mechanics. He also made contributions to solid-state physics and optics and supervised the work of a number of notable physicists in the 1920s and 1930s. Born won the 1954 Nobel Prize in Physics for his "fundamental research in quantum mechanics, especially in the statistical interpretation of the wave function".

Born entered the University of Göttingen in 1904, where he found the three renowned mathematicians Felix Klein, David Hilbert, and Hermann Minkowski. He wrote his Ph.D. thesis on the subject of "Stability of Elastica in a Plane and Space", winning the University's Philosophy Faculty Prize. In 1905, he began researching special relativity with Minkowski, and subsequently wrote his habilitation thesis on the Thomson model of the atom. A chance meeting with Fritz Haber in Berlin in 1918 led to discussion of the manner in which an ionic compound is formed when a metal reacts with a halogen, which is today known as the Born–Haber cycle.

In the First World War, after originally being placed as a radio operator, he was moved to research duties regarding sound ranging due to his specialist knowledge. In 1921, Born returned to Göttingen, arranging another chair for his long-time friend and colleague James Franck. Under Born, Göttingen became one of the world's foremost centres for physics. In 1925, Born and Werner Heisenberg formulated the matrix mechanics representation of quantum mechanics. The following year, he formulated the now-standard interpretation of the probability density function for ψ*ψ in the Schrödinger equation, for which he was awarded the Nobel Prize in 1954. His influence extended far beyond his own research. Max Delbrück, Siegfried Flügge, Friedrich Hund, Pascual Jordan, Maria Goeppert-Mayer, Lothar Wolfgang Nordheim, Robert Oppenheimer, and Victor Weisskopf all received their Ph.D. degrees under Born at Göttingen, and his assistants included Enrico Fermi, Werner Heisenberg, Gerhard Herzberg, Friedrich Hund, Pascual Jordan, Wolfgang Pauli, Léon Rosenfeld, Edward Teller, and Eugene Wigner.

In January 1933, the Nazi Party came to power in Germany, and Born, who was Jewish, was suspended from his professorship at the University of Göttingen. He emigrated to the United Kingdom, where he took a job at St John's College, Cambridge, and wrote a popular science book, The Restless Universe, as well as Atomic Physics, which soon became a standard textbook. In October 1936, he became the Tait Professor of Natural Philosophy at the University of Edinburgh, where, working with German-born assistants E. Walter Kellermann and Klaus Fuchs, he continued his research into physics. Born became a naturalised British subject on 31 August 1939, one day before World War II broke out in Europe. He remained at Edinburgh until 1952. He retired to Bad Pyrmont, in West Germany, and died in hospital in Göttingen on 5 January 1970.

Here are some events that happened on December 18th. It could be an event or a person that died or was born on that day

1737 Died: Antonio Stradivari, Italian instrument maker (b. 1644)

Antonio Stradivari (1644 – 18 December 1737) was an Italian luthier and a crafter of string instruments such as violins, cellos, guitars, violas, and harps. The Latinized form of his surname, Stradivarius, as well as the colloquial Strad are terms often used to refer to his instruments. It is estimated that Stradivari produced 1,116 instruments, 960 of which were violins. Around 650 instruments survived, including 450 to 512 violins.

1863 Born: Archduke Franz Ferdinand of Austria (d. 1914)

Archduke Franz Ferdinand Carl Ludwig Joseph Maria of Austria (18 December 1863 – 28 June 1914) was the heir presumptive to the throne of Austria-Hungary. His assassination in Sarajevo precipitated Austria-Hungary's declaration of war against Serbia, which in turn triggered a series of events that eventually led to Austria-Hungary's allies and Serbia's declaring war on each other, starting World War I.

1878 Born: Joseph Stalin, Georgian-Russian marshal and politician, 4th Premier of the Soviet Union (d. 1953)

Joseph Vissarionovich Stalin (18 December 1878 – 5 March 1953) was a Georgian revolutionary and Soviet politician who led the Soviet Union from the mid–1920s until 1953 as the general secretary of the Communist Party of the Soviet Union (1922–1952) and premier of the Soviet Union (1941–1953). Despite initially governing the Soviet Union as part of a collective leadership, he eventually consolidated power to become the country's de facto dictator by the 1930s. A communist ideologically committed to the Leninist interpretation of Marxism, Stalin formalised these ideas as Marxism–Leninism, while his own policies are known as Stalinism.

Born to a poor family in Gori in the Russian Empire (now Georgia), Stalin joined the Marxist Russian Social Democratic Labour Party as a youth. He edited the party's newspaper, Pravda, and raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings, and protection rackets. Repeatedly arrested, he underwent several internal exiles. After the Bolsheviks seized power during the 1917 October Revolution and created a one-party state under Lenin's newly renamed Communist Party, Stalin joined its governing Politburo. Serving in the Russian Civil War before overseeing the Soviet Union's establishment in 1922, Stalin assumed leadership over the country following Lenin's 1924 death. Under Stalin, "Socialism in One Country" became a central tenet of the party's dogma. Through the Five-Year Plans, the country underwent agricultural collectivisation and rapid industrialisation, creating a centralised command economy. This led to significant disruptions in food production that contributed to the famine of 1932–33. To eradicate accused "enemies of the working class", Stalin instituted the "Great Purge", in which over a million were imprisoned and at least 700,000 executed between 1934 and 1939. By 1937, he had complete personal control over the party and state.

Stalin's government promoted Marxism–Leninism abroad through the Communist International and supported European anti-fascist movements during the 1930s, particularly in the Spanish Civil War. In 1939, it signed a non-aggression pact with Nazi Germany, resulting in the Soviet invasion of Poland. Germany ended the pact by invading the Soviet Union in 1941. Despite initial setbacks, the Soviet Red Army repelled the German incursion and captured Berlin in 1945, ending World War II in Europe. The Soviets annexed the Baltic states and helped establish Soviet-aligned governments throughout Central and Eastern Europe, China, and North Korea. The Soviet Union and the United States emerged from the war as global superpowers. Tensions arose between the Soviet-backed Eastern Bloc and U.S.-backed Western Bloc which became known as the Cold War. Stalin led his country through the post-war reconstruction, during which it developed a nuclear weapon in 1949. In these years, the country experienced another major famine and an anti-semitic campaign peaking in the doctors' plot. After Stalin's death in 1953 he was eventually succeeded by Nikita Khrushchev, who denounced his predecessor and initiated the de-Stalinisation of Soviet society.

Widely considered one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement which revered him as a champion of the working class and socialism. Since the dissolution of the Soviet Union in 1991, Stalin has retained popularity in Russia and Georgia as a victorious wartime leader who established the Soviet Union as a major world power. Conversely, his totalitarian government has been widely condemned for overseeing mass repressions, ethnic cleansing, deportations, hundreds of thousands of executions, and famines which killed millions.

1913 Born: Willy Brandt, German politician, 4th Chancellor of Germany, Nobel Prize laureate (d. 1992)

Willy Brandt (18 December 1913 – 8 October 1992) was a German statesman who was leader of the Social Democratic Party of Germany (SPD) from 1964 to 1987 and served as Chancellor of the Federal Republic of Germany (West Germany) from 1969 to 1974. He was awarded the Nobel Peace Prize in 1971 for his efforts to strengthen cooperation in western Europe through the EEC and to achieve reconciliation between West Germany and the countries of Eastern Europe. He was the first Social Democrat chancellor since 1930.

Fleeing to Norway and then Sweden during the Nazi regime and working as a left-wing journalist, he took the name Willy Brandt as a pseudonym to avoid detection by Nazi agents, and then formally adopted the name in 1948. Brandt was originally considered one of the leaders of the right wing of the SPD, and earned initial fame as Governing Mayor of West Berlin. He served as Foreign Minister and as Vice Chancellor in Kurt Georg Kiesinger's cabinet, and became chancellor in 1969. As chancellor, he maintained West Germany's close alignment with the United States and focused on strengthening European integration in western Europe, while launching the new policy of Ostpolitik aimed at improving relations with Eastern Europe. Brandt was controversial on both the right wing, for his Ostpolitik, and on the left wing, for his support of American policies, including the Vietnam War, and right-wing authoritarian regimes. The Brandt Report became a recognised measure for describing the general North-South divide in world economics and politics between an affluent North and a poor South. Brandt was also known for his fierce anti-communist policies at the domestic level, culminating in the Radikalenerlass (Anti-Radical Decree) in 1972.

Brandt resigned as chancellor in 1974, after Günter Guillaume, one of his closest aides, was exposed as an agent of the Stasi, the East German secret service.

1936 Died: Andrija Mohorovičić, Croatian meteorologist and seismologist (b. 1857)

Andrija Mohorovičić (23 January 1857 – 18 December 1936) was a Croatian meteorologist and seismologist. He is best known for the eponymous Mohorovičić discontinuity and is considered as one of the founders of modern seismology.

On 8 October 1909 there was an earthquake with its epicentre in the Pokuplje region, 39 km southeast of Zagreb. A number of seismographs had been installed beforehand and these provided invaluable data, upon which he made new discoveries. He concluded that when seismic waves strike the boundary between different types of material, they are reflected and refracted, just as light is when striking a prism, and that when earthquakes occur, two waves—longitudinal and transverse—propagate through the soil with different velocities. By analyzing data from more observation posts, Mohorovičić concluded that the Earth has several layers above a core. He was the first to establish, based on the evidence from seismic waves, the discontinuity that separates the Earth's crust from its mantle. This is now called the Mohorovičić discontinuity or (because of the complexity of that name) Moho. According to Mohorovičić, a layered structure would explain the observation of depths where seismic waves change speed and the difference in chemical composition between rocks from the crust and those from the mantle. From the data, he estimated the thickness of the upper layer (crust) to be 54 km. We know today that the crust is 5–9 km below the ocean floor and 25–60 km below the continents, which are carried on tectonic plates. Subsequent study of the Earth's interior confirmed the existence of the discontinuity under all continents and oceans.

Mohorovičić assumed that the velocity of seismic waves increases with the depth. The function he proposed to calculate the velocity of seismic waves is called the Mohorovičić law. He developed a method for determining earthquake epicenters and constructed curves giving the travel times of seismic waves over distances of up to 10,000 miles from the source. He also proposed the construction of a new type of seismograph for recording the ground horizontal movement, but due to lack of funds the project was never realized.

As early as 1909 Mohorovičić started giving lectures that both architects and building contractors should follow, ahead of his time setting some of the basic principles of earthquake-resistant design. Mohorovičić's theories were visionary and were only truly understood many years later from detailed observations of the effects of earthquakes on buildings, deep focus earthquakes, locating earthquake epicenters, Earth models, seismographs, harnessing the energy of the wind, hail defence and other related elements of the geological body of knowledge known as geoscience.

December 13th in stamps Donatello, Tasman, Siemens, Senoa

Here are some events that happened on December 13th. It could be an event or a person that died or was born on that day

1466 Died: Donatello, Italian painter and sculptor (b. 1386)


Donato di Niccolò di Betto Bardi (c. 1386 – 13 December 1466), better known as Donatello was an Italian sculptor of the Renaissance. Born in Florence, he studied classical sculpture and used this to develop a complete Renaissance style in sculpture, whose periods in Rome, Padua and Siena introduced to other parts of Italy a long and productive career. He worked with stone, bronze, wood, clay, stucco and wax, and had several assistants, with four perhaps being a typical number. Though his best-known works were mostly statues in the round, he developed a new, very shallow, type of bas-relief for small works, and a good deal of his output was larger architectural reliefs.

1642 – Abel Tasman is the first recorded European to sight New Zealand.

Abel Janszoon Tasman (1603 – 10 October 1659) was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was the first known European explorer to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand, and to sight the Fiji islands.

Tasman's ten-month voyage in 1642–43 had significant consequences. By circumnavigating Australia (albeit at a distance) Tasman proved that the small fifth continent was not joined to any larger sixth continent, such as the long-imagined Southern Continent. Further, Tasman's suggestion that New Zealand was the western side of that Southern Continent was seized upon by many European cartographers who, for the next century, depicted New Zealand as the west coast of a Terra Australis rising gradually from the waters around Tierra del Fuego. This theory was eventually disproved when Captain Cook circumnavigated New Zealand in 1769.

1816 Born: Werner von Siemens, German engineer and businessman, founded Siemens (d. 1892)

Ernst Werner Siemens (von Siemens from 1888; 13 December 1816 – 6 December 1892) was a German electrical engineer, inventor and industrialist. Siemens's name has been adopted as the SI unit of electrical conductance, the siemens. He was also the founder of the electrical and telecommunications company Siemens.

Ernst Werner Siemens was born in Lenthe, today part of Gehrden, near Hannover, in the Kingdom of Hanover in the German Confederation, the fourth child (of fourteen) of a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. He was a brother of Carl Heinrich von Siemens and Carl Wilhelm Siemens, sons of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839).


After finishing school, Siemens intended to study at the Bauakademie Berlin. However, since his family was highly indebted and thus could not afford to pay the tuition fees, he chose to join the Prussian Military Academy's School of Artillery and Engineering, between the years 1835-1838, instead, where he received his officers training. Siemens was thought of as a good soldier, receiving various medals, and inventing electrically-charged sea mines, which were used to combat a Danish blockade of Kiel.

Upon returning home from war, he chose to work on perfecting technologies that had already been established and eventually became known worldwide for his advances in various technologies. In 1843 he sold the rights to his first invention to Elkington of Birmingham. Siemens invented a telegraph that used a needle to point to the right letter, instead of using Morse code. Based on this invention, he founded the company Telegraphen-Bauanstalt von Siemens & Halske on 1 October 1847, with the company opening a workshop on 12 October.

The company was internationalised soon after its founding. One brother of Werner represented him in England (Sir William Siemens) and another in St. Petersburg, Russia (Carl von Siemens), each earning recognition. Following his industrial career, he was ennobled in 1888, becoming Werner von Siemens. He retired from his company in 1890 and died in 1892 in Berlin.

The company, reorganized as Siemens & Halske AG, Siemens-Schuckertwerke and – since 1966 – Siemens AG was later led by his brother Carl, his sons Arnold, Wilhelm, and Carl Friedrich, his grandsons Hermann and Ernst and his great-grandson Peter von Siemens. Siemens AG is one of the largest electrotechnological firms in the world. The von Siemens family still owns 6% of the company shares (as of 2013) and holds a seat on the supervisory board, being the largest shareholder.

Apart from the pointer telegraph Siemens made several contributions to the development of electrical engineering and is therefore known as the founding father of the discipline in Germany. He built the world's first electric elevator in 1880. His company produced the tubes with which Wilhelm Conrad Röntgen investigated x-rays. He claimed invention of the dynamo although others invented it earlier. On 14 December 1877 he received German patent No. 2355 for an electromechanical "dynamic" or moving-coil transducer, which was adapted by A. L. Thuras and E. C. Wente for the Bell System in the late 1920s for use as a loudspeaker. Wente's adaptation was issued US patent 1,707,545 in 1929. Siemens is also the father of the trolleybus which he initially tried and tested with his "Elektromote" on 29 April 1882.

1881 Died: August Šenoa, Croatian author and poet (b. 1838)

August Ivan Nepomuk Eduard Šenoa (14 November 1838 – 13 December 1881) was a novelist. Born to an ethnic German and Slovak family, Šenoa became a key figure in the develoment of an independent literary tradition in the Croatian language and shaping the emergence of the urban Croatian identity of Zagreb and its surroundings at a time when Austrian control was weaning. He was a literary transitional figure, who helped bring Croatian literature from Romanticism to Realism and introduced the historical novel to Croatia. He wrote more than ten novels, among which the most notable are:

Zlatarovo zlato (Goldsmith's gold; 1871)
Čuvaj se senjske ruke (Pirates of Senj; 1876)
Seljačka buna (Peasants' revolt; 1877)
Diogenes (1878)

Šenoa was one of the most popular Croatian novelists and the author of the popular patriotic song "Živila Hrvatska".
