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.
Germany-Democratic Republic | KM# 78 | J-1575 | Commemorating the 75th obit of Ernst Abbe Ernst Karl Abbe (23 January 1840 – 14 January 1905) was a German physicist, optical scientist, entrepreneur, and social reformer. Together with Otto Schott and Carl Zeiss, he developed numerous optical instruments. He was also a co-owner of Carl Zeiss AG, a German manufacturer of scientific microscopes, astronomical telescopes, planetariums, and other advanced optical systems.
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.
Germany-Democratic Republic | KM# 119.1 | J-1617 | Commemorating the 750th birthday of Berlin Berlin is the capital and largest city of Germany by both area and population.

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.
