Title: Dominique, comte de Cassini
Content:  Jean-Dominique, comte de Cassini (30 June 1748 – 18 October 1845) was a French astronomer, son of César-François Cassini de Thury. Cassini was born at the Paris Observatory. He succeeded his father as director of the observatory in 1784; but his plans for its restoration and re-equipment were wrecked in 1793 by the animosity of the National Assembly. His position having become intolerable, he resigned on 6 September and was thrown into prison in 1794, but released after seven months. He then withdrew to Thury, where he died in 1845. In 1770, he published an account of a voyage to America in

During this time, Cassini's method of determining longitude was used to measure the size of France accurately for the first time. The country turned out to be considerably smaller than expected, and the king quipped that Cassini had taken more of his kingdom from him than he had won in all his wars. On 14 July 1673 Cassini obtained the benefits of French citizenship. In 1674 he married Geneviève de Laistre, the daughter of the lieutenant general of the comté of Clermont. "From this marriage Cassini had two sons; the younger, Jacques Cassini, succeeded him as astronomer and geodesist under the name of Cassini II." In 1711 Cassini went blind and he died on 14 September 1712 in Paris at the age of 87.
Title: Giovanni Domenico Cassini
Content:  Giovanni Domenico Cassini, also known as Jean-Dominique Cassini (8 June 1625 – 14 September 1712) was an Italian (naturalised French) mathematician, astronomer and engineer. Cassini was born in Perinaldo, near Imperia, at that time in the County of Nice, part of the Savoyard state. Cassini is known for his work on astronomy and engineering. He discovered four satellites of the planet Saturn and noted the division of the rings of Saturn; the Cassini Division was named after him. Giovanni Domenico Cassini was also the first of his family to begin work on the project of creating a topographic map of France. The Cassini space probe, launched in 1997, was named after him and became the fourth to visit the planet Saturn and the first to orbit the planet.
Title: Jacques Cassini
Content:  Jacques Cassini (18 February 1677 – 16 April 1756) was a French astronomer, son of the famous Italian astronomer Giovanni Domenico Cassini. Cassini was born at the Paris Observatory. Admitted at the age of seventeen to membership of the French Academy of Sciences, he was elected in 1696 a fellow of the Royal Society of London, and became maître des comptes in 1706. Having succeeded to his father's position at the observatory in 1712, in 1713 he extended the Paris meridian, measuring the arc of the meridian from Dunkirk to Perpignan, and published the results in a volume entitled Traité de la grandeur et

He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1788. Cassini's Mémoires pour servir à l’histoire de l’observatoire de Paris (1810) embodied portions of an extensive work, the prospectus of which he had submitted to the Academy of Sciences in 1774. The volume included his Eloges of several academicians, and the biography of his great-grandfather, Giovanni Cassini. His youngest son Henri was a botanist of some note.

Title: Giovanni Domenico Cassini
Content:   Cassini's determinations of the rotational periods of Jupiter, Mars and Venus in 1665–1667 enhanced his fame, and in 1669, with the reluctant assent of the Pope, he moved to France and through a grant from Louis XIV of France helped to set up the Paris Observatory, which opened in 1671; he would remain the director of the observatory for the rest of his career until his death in 1712. For the remaining forty-one years of his life Cassini served as astronomer/astrologer to Louis XIV ("The Sun King"); serving the expected dual role yet focusing the overwhelming majority of his time on astronomy rather than the astrology he had studied so much in his youth. Cassini thoroughly adopted his new country, to the extent that he became interchangeably known as Jean-Dominique Cassini, although that is 
Title: Henri Cassini
Content:  Count Alexandre Henri Gabriel de Cassini (May 9, 1781 – April 23, 1832) was a French botanist and naturalist, who specialised in the sunflower family (Asteraceae) (then known as family Compositae). He was the youngest of five children of Jacques Dominique, Comte de Cassini, famous for completing the map of France, who had succeeded his father as the director of the Paris Observatory. He was also the great-great-grandson of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings. The genus Cassinia was named in his honour by the botanist Robert Brown. He named many flowering plants and new genera in the sunflower family (Asteraceae), many of them from North America. He published 65 papers and 11 reviews in the [Nouveau] Bulletin des Sciences of the  Société Philomatique de Paris between 1812 and 1821. In 1825, Cassini placed the North American taxa of Prenanthes (family Asteraceae, tribe Lactuceae) in a new genus Nabalus. In 1828 he named Dugaldia hoopesii for the Scottish naturalist Dugald Stewart (1753–1828).

In 1783, he sent a memoir to the Royal Society in which he proposed a trigonometric survey connecting the observatories of Paris and Greenwich for the purpose of better determining the latitude and longitude of the latter. His proposal was accepted, resulting in the Anglo-French Survey (1784–1790). The results of the survey were published in 1791. He visited England for the purposes of the work with Pierre Méchain and Adrien-Marie Legendre, and the three met William Herschel at Slough. He completed
