Carl Zeiss
Carl Zeiss (; 11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman. In 1846 he founded his workshop, which is still in business as Carl Zeiss AG. Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world. Birth and family His father Johann Gottfried August Zeiss (1785–1849) was born in Rastenberg, where his forefathers had worked as artisans for over 100 years. August moved with his parents to Buttstädt, a small regional capital north of Weimar, where he married Johanna Antoinette Friederike Schmith (1786–1856). Ca ...

Saxe-Weimar-Eisenach
Saxe-Weimar-Eisenach (german: Sachsen-Weimar-Eisenach) was a historical German state, created as a duchy in 1809 by the merger of the Ernestine duchies of Saxe-Weimar and Saxe-Eisenach, which had been in personal union since 1741. It was raised to a grand duchy in 1815 by resolution of the Vienna Congress. In 1903, it officially changed its name to the Grand Duchy of Saxony (german: Großherzogtum Sachsen), but this name was rarely used. The Grand Duchy came to an end in the German Revolution of 1918–19 with the other monarchies of the German Empire. It was succeeded by the Free State of Saxe-Weimar-Eisenach, which was merged into the new Free State of Thuringia two years later. The full grand ducal style was Grand Duke of Saxe-Weimar- Eisenach, Landgrave in Thuringia, Margrave of Meissen, Princely Count of Henneberg, Lord of Blankenhayn, Neustadt and Tautenburg. The Saxe-Weimar-Eisenach branch has been the most genealogically senior extant branch of the House ...

Joseph Von Fraunhofer
Joseph Ritter von Fraunhofer (; ; 6 March 1787 – 7 June 1826) was a German physicist and optical lens manufacturer. He made optical glass, an achromatic telescope, and objective lenses. He also invented the spectroscope and developed diffraction grating. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines. The German research organization Fraunhofer Society, which is Europe's biggest Society for the advancement of applied research, is named after him. Biography Joseph Fraunhofer was the 11th child, born into a Roman Catholic family in Straubing, in the Electorate of Bavaria, to Franz Xaver Fraunhofer and Maria Anna Fröhlich. He was orphaned at the age of 11 and started working as an apprentice to a harsh glassmaker named Philipp Anton Weichelsberger.

Paternalistic
Paternalism is action that limits a person's or group's liberty or autonomy and is intended to promote their own good. Paternalism can also imply that the behavior is against or regardless of the will of a person, or also that the behavior expresses an attitude of superiority. Paternalism, paternalistic and paternalist have all been used as a pejorative for example in the context of societal and/or political realms and references. Some such as John Stuart Mill think paternalism to be appropriate towards children, saying: Paternalism towards adults is sometimes thought of as treating them as if they were children. Etymology The word ''paternalism'' derives from the adjective ''paternal'', which entered the English language in the 15th century from Old French ''paternel'' (cf. Old Occitan ''paternal'', as in Catalan, Spanish and Portuguese), itself from Medieval Latin ''paternalis''. The classical Latin equivalent was ''paternus'' "fatherly", from ''pater'' "father".

Thaler
A thaler (; also taler, from german: Taler) is one of the large silver coins minted in the states and territories of the Holy Roman Empire and the Habsburg monarchy during the Early Modern period. A ''thaler'' size silver coin has a diameter of about and a weight of about 25 to 30 grams (roughly 1 ounce). The word is shortened from ''Joachimsthaler'', the original ''thaler'' coin minted in Joachimstal, Bohemia, from 1520. While the first standard coin of the Holy Roman Empire was the '' Guldengroschen'' of 1524, its longest-lived coin was the '' Reichsthaler (Reichstaler)'', which contained Cologne Mark of fine silver (or 25.984 g), and which was issued in various versions from 1566 to 1875. From the 17th century a lesser-valued '' North German thaler'' currency unit emerged, which by the 19th century became par with the '' Vereinsthaler''. The ''thaler'' silver coin type continued to be minted until the 20th century in the form of the Mexican peso until 1914, the fi ...

Career Matthias Jakob Schleiden was born in Hamburg. on 5 April 1804. His father was the municipal physician of Hamburg. Schleiden pursued legal studies graduating in 1827. He then established a legal practice but after a period of emotional depression and attempted suicide, he changed professions. He studied natural science at the University of Göttingen in Göttingen, Germany, but transferred to the University of Berlin in 1835 to study plants. Johann Horkel, Schleiden's uncle, encouraged him to study plant embryology. He soon developed his love for botany and cats into a full-time pursuit. Schleiden preferred to study plant structure under the microscope. As a professor of botany at the University of Jena, he wrote ''Contributions to our Knowledge of Phytogenesis'' (1838), in which he stated that all plants are ...
