Josef Rodenstock
Josef Rodenstock (11 April 1846 – 18 February 1932) was a German industrialist and the founder of Rodenstock, a manufacturer of optical systems. Josef Rodenstock was born in Ershausen, in the Prussian Province of Saxony. The eldest son of the "wool comber, master mechanic and merchant" Georg Rodenstock (1819-1894), he was 14 years old when he started selling haberdashery, without trader's or travel's licence, to support his family. He learned soon how to refill damaged tubes of mercury barometers, which he bought from another haberdasher and sold "with some advantage" on his sale trips. He even learned how to make new barometers by himself. So the family began mass production in the early 1861. They had made the glass tubes in the Thuringian Forest and the dials - printed with the family name Rodenstock - in Würzburg. In 1877 he founded the precision workshop "G. Rodenstock" together with his brother Michael in Würzburg. They sold mathematical, physical and optical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From The Province Of Saxony
A person ( : 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 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 use as a plural form of ...

List Of Monarchs Of Prussia
The monarchs of Prussia were members of the House of Hohenzollern who were the hereditary rulers of the former German state of Prussia from its founding in 1525 as the Duchy of Prussia. The Duchy had evolved out of the Teutonic Order, a Roman Catholic crusader state and theocracy located along the eastern coast of the Baltic Sea. The Teutonic Knights were under the leadership of a Grand Master, the last of whom, Albert, converted to Protestantism and secularized the lands, which then became the Duchy of Prussia. The Duchy was initially a vassal of the Kingdom of Poland, as a result of the terms of the Prussian Homage whereby Albert was granted the Duchy as part of the terms of peace following the Prussian War. When the main line of Prussian Hohenzollerns died out in 1618, the Duchy passed to a different branch of the family, who also reigned as Electors of Brandenburg in the Holy Roman Empire. While still nominally two different territories, Prussia under the suzerainty of P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
