Paul Oswald Ahnert
Paul Oswald Ahnert (22 November 1897 – 27 February 1989) was a German astronomer. He first became famous in Germany for publishing the ''"Kalender für Sternfreunde"'' from 1948 until 1988, an annual calendar of astronomical events. The minor planet 3181 Ahnert is named in his honor. Ahnert was born in Chemnitz, Kingdom of Saxony. During the First World War he served as an ordinary German field-soldier. After the war he became a member of the Social Democratic Party of Germany (SPD) and was a committed opponent of the rise of militarism and right wing revanchism in Germany. Between 1919 and 1933 he worked as an elementary school teacher. In addition to this he was an ambitious amateur astronomer and in 1923 his first article was published in the scientific journal Astronomische Nachrichten (AN 219 (1923), 165–170). He reported about long period variables he had observed from his private observatory. When Adolf Hitler became Chancellor in 1933 the Nazi regime removed P ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Nazi Concentration Camps
From 1933 to 1945, Nazi Germany operated more than a thousand concentration camps, (officially) or (more commonly). The Nazi concentration camps are distinguished from other types of Nazi camps such as forced-labor camps, as well as concentration camps operated by Germany's allies. on its own territory and in parts of German-occupied Europe. The first camps were established in March 1933 immediately after Adolf Hitler became Chancellor of Germany. Following the 1934 purge of the SA, the concentration camps were run exclusively by the SS via the Concentration Camps Inspectorate and later the SS Main Economic and Administrative Office. Initially, most prisoners were members of the Communist Party of Germany, but as time went on different groups were arrested, including "habitual criminals", "asocials", and Jews. After the beginning of World War II, people from German-occupied Europe were imprisoned in the concentration camps. Following Allied military victories, the ...

People From Chemnitz
A person (plural, : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its us ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ...
