Alexandre Gustave Eiffel ( /ˈaɪfəl/ French pronunciation: [efɛl]) (December 15, 1832 – December 27, 1923) was a French civil engineer and architect. A graduate of the École Centrale des Arts et Manufactures, he made his name with various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France. After his retirement from engineering, Eiffel concentrated his energies on research into meteorology and aerodynamics, making important contributions in both fields.

Gustave Eiffel was born in Dijon, in the Côte-d'Or department of France, the first child of Alexandre and Catherine Eiffel. The family was originally from Germany, being descended from Jean-René Bönickhausen, who emigrated from Marmagen and settled in Paris at the beginning of the eighteenth century. The family adopted the name Eiffel as a reference to the Eifel mountains in the region from which it had come. Although the family always used the name Eiffel, Gustave's name was registered at birth as Bönickhausen, and was not formally changed to Eiffel until 1880.

William Saurin (1757 – 11 January 1839) was an Irish lawyer and politician. He was Attorney-General for Ireland from 1807 to 1822, and for much of that period effective head of the Irish administration.

Saurin was born in Ulster, the son of a Presbyterian minister of French Huguenot descent. Educated at the University of Dublin, he was called to the Bar in 1780 and after a slow start became one of its acknowledged leaders.

Saurin was a passionate opponent of the Act of Union and entered the Irish House of Commons as member for Blessington to combat it: his speeches against Union were considered among the finest on the topic. That he was appointed Attorney-General for Ireland despite his opposition to the Union and his repeated refusal to stand for the post-Union Parliament is a tribute to his legal eminence.

His tenure as Attorney-General is remarkable not only for its length but for his effective dominance of the Irish administration, a position never equalled by any other holder of the office. The fact that the Lord Lieutenant of Ireland was usually absent and that the Lord Chancellor of Ireland, Lord Manners was not familiar with the Irish political scene gave Saurin the opportunity to direct the Irish Government of which he took full advantage. As an Ulster Presbyterian it was perhaps natural that he should combine sympathy for the Orange Order with hostility to Catholic Emancipation; but his perceived bias against Catholics destroyed his popularity.

Jules François Camille Ferry (French pronunciation: [ʒyl feʁi]; 5 April 1832 – 17 March 1893) was a French statesman and republican. He was a promoter of laicism and colonial expansion.

Born in Saint-Dié, in the Vosges département, France, he studied law, and was called to the bar at Paris in 1854, but soon went into politics, contributing to various newspapers, particularly to Le Temps. He attacked the Second French Empire with great violence, directing his opposition especially against Baron Haussmann, prefect of the Seine département. A series of his articles in Le Temps were later republished as The Fantastic Tales of Haussmann (1868). Elected republican deputy for Paris in 1869, he protested against the declaration of war with Germany, and on 6 September 1870 was appointed prefect of the Seine by the Government of National Defense.

In this position he had the difficult task of administering Paris during the siege, and after the Paris Commune was obliged to resign (5 June 1871). From 1872 to 1873 he was sent by Adolphe Thiers as minister to Athens, but returned to the chamber as deputy for the Vosges, and became one of the leaders of the republican party. When the first republican ministry was formed under WH Waddington on 4 February 1879, he was one of its members, and continued in the ministry until 30 March 1885, except for two short interruptions (from 10 November 1881 to 30 January 1882, and from 29 July 1882 to 21 February 1883), first as minister of education and then as minister of foreign affairs. A leader of the Opportunist Republicans faction, he was twice premier (1880–1881 and 1883–1885). He was a Freemason and a member of the Alsace-Lorraine Lodge founded in Paris in 1782.
