Yvelines (French pronunciation: [ivlin]) is a French department in the region of Île-de-France.

Yvelines was created from the western part of the defunct department of Seine-et-Oise on 1 January 1968 in accordance with a law passed on 10 January 1964 and a décret d'application (a decree specifying how a law should be enforced) from 26 February 1965.

It gained the communes of Châteaufort and Toussus-le-Noble from the adjacent department of Essonne in 1969.

The departmental capital, Versailles, which grew up around Louis XIV's château, was also the French capital for more than a century under the Ancien Régime and again between 1871 and 1879 during the early years of the Third Republic. Since then the château has continued to welcome the parlement when called upon to sit in a congressional sitting, jointly with the upper house in order to enact constitutional changes or, as happened most recently in June 2009, to listen to a formal declaration by the president.

Yvelines is bordered by the departments of Val-d'Oise on the north, Hauts-de-Seine on the east, Essonne on the southeast, Eure-et-Loir on the southwest, and Eure on the west.

Gilbert Montagné (born 28 December 1951 in Paris) is a French musician, both a pianist and organist, as well as a singer. Blind from birth, he is best remembered for his international hit "The Fool", which was a number 1 single across Europe in 1971. In France he is still a popular albums and concert artist, having toured with the likes of Johnny Hallyday.

Jacques Dutronc (born 28 April 1943 in Paris; French pronunciation: [ʒak dytʁɔ̃]) is a French singer, songwriter, guitarist, composer, and actor. He has been married to singer Françoise Hardy since 30 March 1981 and the two have a son (jazz guitarist Thomas Dutronc, born 1973). He also has been a longtime songwriting collaborator with Jacques Lanzmann. Some of Dutronc best known hits include "Il Est Cinq Heures, Paris S'éveille" (a chanson tune akin to "Waterloo Sunset" by The Kinks that All Music Guide has called "his finest hour"), "Le Responsable", and "Les Cactus".

Dutronc played guitar in the rock group El Toro et les Cyclones. He wrote successful songs for Françoise Hardy in the 1960s before moving on to pursue a successful solo career. His music incorporated traditional French pop and French rock as well as styles such as psychedelic rock and garage rock. He later branched out into film acting, starting in 1973. He earned a Cesar for Best Actor for the leading role in Van Gogh, which was directed by Maurice Pialat. According to the All Music Guide, Dutronc is "one of the most popular performers in the French-speaking world", although he "remains little known in English speaking territories" aside from a cult following in the U.K.

This article is about the political philosopher. For the singer, see Yves Simon (singer).

Yves René Marie Simon (March 14, 1903–1961) was a French Catholic political philosopher.

Simon studied under Jacques Maritain at the Institut Catholique de Paris. He taught at the Institut Catholique de Lille from 1930 to 1938. In 1938, he came to the University of Notre Dame in South Bend, Indiana, as a visiting professor. He was unable to return to France because of World War II, and after the war he remained as a professor at Notre Dame until 1948. He then joined the Committee on Social Thought, at the University of Chicago. He remained at the University of Chicago until his death. In 1975, Maurice Cranston called him one of the world's "most original and distinguished political theorists."

Simon left many materials unfinished at his death, and many of his publications have only appeared after his death. His son, Anthony O. Simon, has taken on the role of director of the Yves R. Simon Institute, which contributes to the effort to publish such materials. Simon's papers are at the University of Notre Dame.
