Cosimo Alessandro Collini (Florence 14 October 1727-Mannheim, 21 March 1806) was an Italian historian and Voltaire's secretary from 1752 to 1756.

The city is at the centre of the larger densely populated Rhine-Neckar Metropolitan Region which has a population of 2,400,000 and is Germany's eighth-largest metropolitan region.

Voltaire French writer, historian, and philosopher

François-Marie Arouet, known by his nom de plumeVoltaire, was a French Enlightenment writer, historian and philosopher famous for his wit, his criticism of Christianity, especially the Roman Catholic Church, and his advocacy of freedom of religion, freedom of speech, and separation of church and state.



Born into a noble family, he studied law and met Voltaire in Berlin in 1750 and was taken on as his secretary in April 1752. [1] When Voltaire left the service of Frederick the Great Collini accompanied him, and was confined with him and Madame Denis on Frederick’s orders for three weeks in Frankfurt. [2] In 1755 the young Jean-Louis Wagnière was made his assistant, and just over a year later, took Collini's place when he was dismissed from Voltaire's service for insulting Madame Denis. [3]

Berlin Capital of Germany

Berlin is the capital and largest city of Germany by both area and population. Its 3,748,148 (2018) inhabitants make it the second most populous city proper of the European Union after London. The city is one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with its capital, Potsdam. The two cities are at the center of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of more than 30,000 km², Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions.

Frederick the Great king of Prussia

Frederick II ruled the Kingdom of Prussia from 1740 until 1786, the longest reign of any Hohenzollern king. His most significant accomplishments during his reign included his military victories, his reorganization of Prussian armies, his patronage of the arts and the Enlightenment and his final success against great odds in the Seven Years' War. Frederick was the last Hohenzollern monarch titled King in Prussia and declared himself King of Prussia after achieving sovereignty over most historically Prussian lands in 1772. Prussia had greatly increased its territories and became a leading military power in Europe under his rule. He became known as Frederick the Great and was nicknamed Der Alte Fritz by the Prussian people and eventually the rest of Germany.

Frankfurt Place in Hesse, Germany

Frankfurt is a metropolis and the largest city of the German federal state of Hesse, and its 746,878 (2017) inhabitants make it the fifth-largest city of Germany after Berlin, Hamburg, Munich, and Cologne. On the River Main, it forms a continuous conurbation with the neighbouring city of Offenbach am Main, and its urban area has a population of 2.3 million. The city is at the centre of the larger Rhine-Main Metropolitan Region, which has a population of 5.5 million and is Germany's second-largest metropolitan region after the Rhine-Ruhr Region. Since the enlargement of the European Union in 2013, the geographic centre of the EU is about 40 km (25 mi) to the east of Frankfurt's central business district. Like France and Franconia, the city is named after the Franks. Frankfurt is the largest city in the Rhine Franconian dialect area.

He then entered the service of Charles Theodore, Elector of Bavaria as his private secretary and historiographer. In 1763 he became a member of the Palatine Academy of Sciences and director of the Mannheim Cabinet of Natural History. In 1764 he was the first person to describe the pterosaur that Georges Cuvier went on the identify, seventeen years later, as a flying reptile.

Charles Theodore, Elector of Bavaria German nobleman and elector

Charles Theodore reigned as Prince-elector and Count Palatine from 1742, as Duke of Jülich and Berg from 1742 and also as prince-elector and Duke of Bavaria from 1777 to his death. He was a member of the House of Palatinate-Sulzbach, a branch of the House of Wittelsbach.

Pterosaur Flying reptiles of the extinct clade or order Pterosauria

Pterosaurs were flying reptiles of the extinct clade or order Pterosauria. They existed during most of the Mesozoic: from the late Triassic to the end of the Cretaceous. Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger.

Georges Cuvier French naturalist, zoologist and paleontologist (1769–1832)

Jean Léopold Nicolas Frédéric, Baron Cuvier, known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils.

In his later years, he denounced the fanaticism of the French revolutionary wars and in 1799 he defended the collections in his cabinet from destruction, and managed to have them transferred, four years later, to Munich.

A street in Mannheim is named after him, as is the Collini-Center development in the city.

Thomas Arthur, comte de Lally Governor of french India

Thomas Arthur, comte de Lally, baron de Tollendal was a French general of Irish Jacobite ancestry. Lally commanded French forces, including two battalions of his own red-coated Regiment of Lally of the Irish Brigade, in India during the Seven Years' War. After a failed attempt to capture Madras he lost the Battle of Wandiwash to British forces under Eyre Coote and then was forced to surrender the remaining French post at Pondicherry. After a time spent as a prisoner of war in Britain, Lally voluntarily returned to France to face charges where he was beheaded for his alleged failures in India. Ultimately the jealousies and disloyalties of other officers, together with insufficient resources and limited naval support prevented Lally from securing India for France. In 1778, he was publicly exonerated by Louis XVI of his alleged crime.

<i>Dictionnaire philosophique</i> philosophical dictionary by Voltaire

The Dictionnaire philosophique is an encyclopedic dictionary published by Voltaire in 1764. The alphabetically arranged articles often criticize the Roman Catholic Church, Judaism, Islam, and other institutions. The first edition, released in June 1764, went by the name of Dictionnaire philosophique portatif. It was 344 pages and consisted of 73 articles. Later versions were expanded into two volumes consisting of 120 articles. The first editions were published anonymously in Geneva by Gabriel Grasset. Due to the volatile content of the Dictionnaire, Voltaire chose Grasset over his usual publisher to ensure his own anonymity. There were many editions and reprints of the Dictionnaire during Voltaire's lifetime, but only four of them contained additions and modifications. Furthermore, another work published in 1770, Questions sur l'Encyclopédie, which contained reshaped and modified articles from the Encyclopédie always in alphabetical order, led many following editors to join this and the Dictionnaire in a unique opus. The Dictionnaire was a lifelong project for Voltaire. It represents the culmination of his views on Christianity, God, morality and other subjects.

<i>Samson</i> (opera) opera

Samson was an opera by the French composer Jean-Philippe Rameau with a libretto by Voltaire. The work was never staged due to censorship, although Voltaire later printed his text. Rameau intended the opera on the theme of Samson and Delilah as the successor to his debut Hippolyte et Aricie, which premiered in October 1733. Like Hippolyte, Samson was a tragédie en musique in five acts and a prologue. Voltaire had become a great admirer of Rameau's music after seeing Hippolyte and suggested a collaboration with the composer in November 1733. The opera was complete by late summer 1734 and went into rehearsal. However, a work on a religious subject with a libretto by such a notorious critic of the Church was bound to run into controversy and Samson was banned. An attempt to revive the project in a new version in 1736 also failed. The score is lost, although Rameau recycled some of the music from Samson in his later operas.
