Germany-Democratic Republic | KM# 127 | J-1624 | Commemorating the 500th birthday of Thomas Muentzner Thomas Müntzer (c. 1489 – 27 May 1525) was a German preacher and radical theologian of the early Reformation whose opposition to both Martin Luther and the Roman Catholic Church led to his open defiance of late-feudal authority in central Germany. Müntzer was foremost amongst those reformers who took issue with Luther's compromises with feudal authority. He became a leader of the German peasant and plebeian uprising of 1525 commonly known as the German Peasants' War. He was captured after the Battle of Frankenhausen, tortured and executed.

1974 20 Mk Kant PR69DCAM PCGS #395523

Germany-Democratic Republic | KM# 53 | J-1549 | Commemorating the 250th birthday of Immanuel Kant. Immanuel Kant (22 April 1724 – 12 February 1804) was an influential German philosopher in the Age of Enlightenment. In his doctrine of transcendental idealism, he argued that space, time, and causation are mere sensibilities; "things-in-themselves" exist, but their nature is unknowable. In his view, the mind shapes and structures experience, with all human experience sharing certain structural features. In one of his major works, the Critique of Pure Reason (1781; second edition 1787), he drew a parallel to the Copernican revolution in his proposition that worldly objects can be intuited a priori ('beforehand'), and that intuition is therefore independent from objective reality.

1983-A 20 Mk Marx PR69DCAM PCGS #395665

Germany-Democratic Republic | KM# 95 | J-1592 | Commemorating the 100th obit of Karl Marx. Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary. Born in Trier, Germany, Marx studied law and philosophy at university. He married Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and publish his writings, researching in the reading room of the British Museum. His best-known titles are the 1848 pamphlet, The Communist Manifesto, and the three-volume Das Kapital (1867–1883). His political and philosophical thought had enormous influence on subsequent intellectual, economic and political history, and his name has been used as an adjective, a noun and a school of social theory. Marx's critical theories about society, economics and politics – collectively understood as Marxism – hold that human societies develop through class conflict. In capitalism, this manifests itself in the conflict between the ruling classes (known as the bourgeoisie) that control the means of production and the working classes (known as the proletariat) that enable these means by selling their labour power in return for wages. Employing a critical approach known as historical materialism, Marx predicted that, like previous socio-economic systems, capitalism produced internal tensions which would lead to its self-destruction and replacement by a new system known as socialism. For Marx, class antagonisms under capitalism, owing in part to its instability and crisis-prone nature, would eventuate the working class' development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers.[14] Marx actively pressed for its implementation, arguing that the working class should carry out organised revolutionary action to topple capitalism and bring about socio-economic emancipation.[15] Marx has been described as one of the most influential figures in human history, and his work has been both lauded and criticised. His work in economics laid the basis for much of the current understanding of labour and its relation to capital, and subsequent economic thought. Many intellectuals, labour unions, artists and political parties worldwide have been influenced by Marx's work, with many modifying or adapting his ideas. Marx is typically cited as one of the principal architects of modern social science.

Luther was ordained to the priesthood in 1507. He came to reject several teachings and practices of the Roman Catholic Church; in particular, he disputed the view on indulgences. Luther proposed an academic discussion of the practice and efficacy of indulgences in his Ninety-five Theses of 1517. His refusal to renounce all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Holy Roman Emperor.

Germany-Democratic Republic | KM# 110 | J-1609 | Sanssouci Sanssouci is a historical building in Potsdam, near Berlin. Built by Frederick the Great, King of Prussia, as his summer palace, it is often counted among the German rivals of Versailles. While Sanssouci is in the more intimate Rococo style and is far smaller than its French Baroque counterpart, it too is notable for the numerous temples and follies in the park. The palace was designed/built by Georg Wenzeslaus von Knobelsdorff between 1745 and 1747 to fulfill King Frederick's need for a private residence where he could relax away from the pomp and ceremony of the Berlin court. The palace's name emphasises this; it is a French phrase (sans souci), which translates as "without concerns", meaning "without worries" or "carefree", symbolising that the palace was a place for relaxation rather than a seat of power. The name in past times reflected a play on words, with the insertion of a comma visible between the words Sans and Souci, viz. Sans, Souci. Kittsteiner theorizes that this could be a philosophical play on words, meaning "without a worry/concern" or it could be some secret personal message which nobody has interpreted, left to posterity by Frederick II.

The descriptive term was often applied to all multilateral activities involving members of the organization, rather than being restricted to the direct functions of Comecon and its organs. This usage was sometimes extended as well to bilateral relations among members because in the system of communist international economic relations, multilateral accords – typically of a general nature – tended to be implemented through a set of more detailed, bilateral agreements. Comecon was set up initially to prevent countries in the Soviet sphere of influence from moving towards that of the United States. It was the Eastern Bloc's response to the formation in Western Europe of the Marshall Plan and the OEEC, which later became the OECD.

Germany-Federal Republic | KM# 182 | J-457 | Commemorating the 50th anniversary of the attempt on Hitler On 20 July 1944, Claus von Stauffenberg and other conspirators attempted to assassinate Adolf Hitler, Führer of Nazi Germany, inside his Wolf's Lair field headquarters near Rastenburg, East Prussia. The name Operation Valkyrie—originally referring to part of the conspiracy—has become associated with the entire event. The apparent aim of the assassination attempt was to wrest political control of Germany and its armed forces from the Nazi Party (including the SS) and to make peace with the Western Allies as soon as possible. The details of the conspirators' peace initiatives remain unknown, but they would have included unrealistic demands for the confirmation of Germany's extensive annexations of European territory. The plot was the culmination of efforts by several groups in the German resistance to overthrow the Nazi German government. The failure of the assassination attempt and the intended military coup d'état that was to follow led the Gestapo to arrest more than 7,000 people, of whom they executed 4,980.

Germany-Federal Republic | KM# 160 | J-435 | Commemorating the 150th anniversary of the Zollverein The Zollverein (pronounced [ˈtsɔlfɛɐ̯ˌʔaɪn]), or German Customs Union, was a coalition of German states formed to manage tariffs and economic policies within their territories. Organized by the 1833 Zollverein treaties, it formally started on 1 January 1834. However, its foundations had been in development from 1818 with the creation of a variety of custom unions among the German states. By 1866, the Zollverein included most of the German states. The foundation of the Zollverein was the first instance in history in which independent states consummated a full economic union without the simultaneous creation of a political federation or union. Prussia was the primary driver behind the creation of the customs union. Austria was excluded from the Zollverein because of its highly protected industry and also because Prince von Metternich was against the idea. By the founding of the North German Confederation in 1867, the Zollverein covered states of approximately 425,000 square kilometres, and had produced economic agreements with several non-German states, including Sweden-Norway. After the founding of the German Empire in 1871, the Empire assumed the control of the customs union. However, not all states within the Empire were part of the Zollverein until 1888 (Hamburg for example). Conversely, though Luxembourg was a state independent of the German Reich, it remained in the Zollverein until 1919.

Germany-Federal Republic | KM# 139 | J-414 | Commemorating the 250th birthday of Immanuel Kant Immanuel Kant (22 April 1724 – 12 February 1804) was an influential German philosopher in the Age of Enlightenment. In his doctrine of transcendental idealism, he argued that space, time, and causation are mere sensibilities; "things-in-themselves" exist, but their nature is unknowable. In his view, the mind shapes and structures experience, with all human experience sharing certain structural features. In one of his major works, the Critique of Pure Reason (1781; second edition 1787), he drew a parallel to the Copernican revolution in his proposition that worldly objects can be intuited a priori ('beforehand'), and that intuition is therefore independent from objective reality.

Beethoven remains one of the most admired composers in the history of Western music; his works rank amongst the most performed of the classical music repertoire. His works span the transition from the classical period to the romantic era in classical music. His career has conventionally been divided into early, middle, and late periods. The "early" period, during which he forged his craft, is typically considered to have lasted until 1802. From 1802 to around 1812, his "middle" period showed an individual development from the "classical" styles of Joseph Haydn and Wolfgang Amadeus Mozart, and is sometimes characterized as "heroic". During this time he began to suffer increasingly from deafness. In his "late" period from 1812 to his death in 1827, he extended his innovations in musical form and expression.

Germany-Federal Republic | KM# 119.1 | J-394 | Commemorating the 250th obit of Gottfried Wilhelm Leibniz Gottfried Wilhelm (von) Leibniz, 1 July 1646 [O.S. 21 June] – 14 November 1716) was a prominent German polymath and one of the most important logicians, mathematicians and natural philosophers of the Enlightenment. As a representative of the seventeenth-century tradition of rationalism, Leibniz developed, as his most prominent accomplishment, the ideas of differential and integral calculus, independently of Isaac Newton's contemporaneous developments. Mathematical works have consistently favored Leibniz's notation as the conventional expression of calculus.[citation needed] It was only in the 20th century that Leibniz's law of continuity and transcendental law of homogeneity found mathematical implementation (by means of non-standard analysis). He became one of the most prolific inventors in the field of mechanical calculators. While working on adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 1685 and invented the Leibniz wheel, used in the arithmometer, the first mass-produced mechanical calculator. He also refined the binary number system, which is the foundation of nearly all digital (electronic, solid-state, discrete logic) computers, including the Von Neumann machine, which is the standard design paradigm, or "computer architecture", followed from the second half of the 20th century, and into the 21st. In philosophy, Leibniz is most noted for his optimism, i.e. his conclusion that our universe is, in a restricted sense, the best possible one that God could have created, an idea that was often lampooned by others such as Voltaire. Leibniz, along with René Descartes and Baruch Spinoza, was one of the three great 17th-century advocates of rationalism. The work of Leibniz anticipated modern logic and analytic philosophy, but his philosophy also assimilates elements of the scholastic tradition, notably that conclusions are produced by applying reason to first principles or prior definitions rather than to empirical evidence. Leibniz made major contributions to physics and technology, and anticipated notions that surfaced much later in philosophy, probability theory, biology, medicine, geology, psychology, linguistics, and computer science. He wrote works on philosophy, politics, law, ethics, theology, history, and philology. Leibniz also contributed to the field of library science. While serving as overseer of the Wolfenbüttel library in Germany, he devised a cataloging system that would serve as a guide for many of Europe's largest libraries. Leibniz's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters, and in unpublished manuscripts. He wrote in several languages, primarily in Latin, French and German but also in English

He was the long-time chairman of the Christian Social Union in Bavaria (CSU) from 1961 until 1988, member of the federal cabinet in different positions between 1953 and 1969 and minister-president of the state of Bavaria from 1978 until 1988. Strauss is also credited as a co-founder of European aerospace conglomerate Airbus. After the 1969 federal elections, West Germany's CDU/CSU alliance found itself out of power for the first time since the founding of the Federal Republic. At this time, Strauss became more identified with the regional politics of Bavaria. While he ran for the chancellorship as the candidate of the CDU/CSU in 1980, for the rest of his life Strauss never again held federal office. From 1978 until his death in 1988, he was the head of the Bavarian government. His last two decades were marked by a fierce rivalry with CDU chairman Helmut Kohl.

During a period of political instability and fragile, short-lived governments, he was generally seen as the most influential cabinet member in most of the Weimar Republic's existence. During his political career, he represented three successive liberal parties; he was the dominant figure of the German People's Party during the Weimar Republic.

Germany-Federal Republic | KM# 116 | J-392 | Max Planck Max Karl Ernst Ludwig Planck, (23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. Planck made many contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes. In 1948 the German scientific institution Kaiser Wilhelm Society (of which Planck was twice president) was renamed Max Planck Society (MPS). The MPS now includes 83 institutions representing a wide range of scientific directions.
