Jean_Luc_Godard

Jean-Luc Godard (UK: GOD-ar, US: goh-DAR; French: [ʒɑ̃ lyk ɡɔdaʁ]; 3 December 1930 – 13 September 2022) was a French and Swiss film director, screenwriter, and film critic. He rose to prominence as a pioneer of the French New Wave film movement of the 1960s, alongside such filmmakers as François Truffaut, Agnès Varda, Éric Rohmer and Jacques Demy. He was arguably the most influential French filmmaker of the post-war era. According to AllMovie, his work "revolutionized the motion picture form" through its experimentation with narrative, continuity, sound, and camerawork. His most acclaimed films include Breathless (1960), Vivre sa vie (1962), Contempt (1963), Band of Outsiders (1964), Alphaville (1965), Pierrot le Fou (1965), Masculin Féminin (1966), Weekend (1967) and Goodbye to Language (2014).During his early career as a film critic for the influential magazine Cahiers du Cinéma, Godard criticised mainstream French cinema's "Tradition of Quality", which de-emphasised innovation and experimentation. In response, he and like-minded critics began to make their own films, challenging the conventions of traditional Hollywood in addition to French cinema. Godard first received global acclaim for his 1960 feature Breathless, helping to establish the New Wave movement. His work makes use of frequent homages and references to film history, and often expressed his political views; he was an avid reader of existentialism and Marxist philosophy, and in 1969 formed the Dziga Vertov Group with other radical filmmakers to promote political works. After the New Wave, his politics were less radical, and his later films came to be about human conflict and artistic representation "from a humanist rather than Marxist perspective."Godard was married three times, to actresses Anna Karina and Anne Wiazemsky, both of whom starred in several of his films, and later to his longtime partner Anne-Marie Miéville. His collaborations with Karina — which included such critically acclaimed films as Vivre sa vie (1962), Bande à part (1964) and Pierrot le Fou (1965) — were called "arguably the most influential body of work in the history of cinema" by Filmmaker magazine. In a 2002 Sight & Sound poll, Godard ranked third in the critics' top ten directors of all time. He is said to have "generated one of the largest bodies of critical analysis of any filmmaker since the mid-twentieth century." His work has been central to narrative theory and has "challenged both commercial narrative cinema norms and film criticism's vocabulary." In 2010, Godard was awarded an Academy Honorary Award.

William,_German_Crown_Prince

Wilhelm, German Crown Prince, Crown Prince of Prussia (Friedrich Wilhelm Victor August Ernst; 6 May 1882 – 20 July 1951) was the eldest child of the last Kaiser, Wilhelm II, German Emperor, and his consort Augusta Victoria of Schleswig-Holstein, and thus a great-grandson of Queen Victoria, and distant cousin to many British Royals, such as Queen Elizabeth II. As Emperor Wilhelm's heir, he was the last Crown Prince of the German Empire and the Kingdom of Prussia, until the abolition of the monarchy.
Wilhelm became crown prince at the age of six in 1888, when his grandfather Frederick III died and his father became emperor. He was crown prince for 30 years until the fall of the empire on 9 November 1918. During World War I, he commanded the 5th Army from 1914 to 1916 and was commander of the Army Group German Crown Prince for the remainder of the war. After his return to Germany in 1923, he fought the Weimar Republic and campaigned for the reintroduction of the monarchy in Germany. After his plans to become president had been blocked by his father, Wilhelm supported Adolf Hitler's rise to power, but when Wilhelm realised that Hitler had no intention of restoring the monarchy, their relationship cooled. Wilhelm became head of the House of Hohenzollern on 4 June 1941 following the death of his father and held the position until his own death on 20 July 1951.

Emperor_Taishō

Yoshihito (Japanese: 嘉仁, 31 August 1879 – 25 December 1926), posthumously honored as Emperor Taishō (大正天皇, Taishō-tennō), was the 123rd emperor of Japan, according to the traditional order of succession, reigning from 1912 until his death in 1926. The era he presided over is known as the Taishō era.
Born to Emperor Meiji and his concubine Yanagiwara Naruko, Yoshihito was proclaimed crown prince in 1888, his two older siblings having died in infancy. In 1900, he married Kujō Sadako, a member of the Kujō family of the Fujiwara clan. The couple had four children: Hirohito, Yasuhito, Nobuhito and Takahito. Upon the death of his father in 1912, Yoshihito ascended the Chrysanthemum Throne. Suffering from neurological issues for the better part of his life, he played only a limited role in politics and from 1919 on undertook no official duties. His reign was characterized by a liberal and democratic shift in political power known as Taishō Democracy. It also saw Japan's entrance in the First World War and the Great Kantō earthquake of 1923.
Yoshihito's declining health led to the appointment of Crown Prince Hirohito as prince regent in 1921. He spent the rest of his life as a recluse. In 1926, Yoshihito died of a heart attack at the age of 47 following a bout of pneumonia. He was succeeded by his eldest son, Hirohito, as Emperor of Japan.

Wilhelm_Roentgen

Wilhelm Conrad Röntgen (; German pronunciation: [ˈvɪlhɛlm ˈʁœntɡən] ; 27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901. In honour of Röntgen's accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him. The unit of measurement roentgen was also named after him.

G.F._Watts

George Frederic Watts (23 February 1817 – 1 July 1904) was a British painter and sculptor associated with the Symbolist movement. He said "I paint ideas, not things." Watts became famous in his lifetime for his allegorical works, such as Hope and Love and Life. These paintings were intended to form part of an epic symbolic cycle called the "House of Life", in which the emotions and aspirations of life would all be represented in a universal symbolic language.

Oscar_II_of_Sweden

Oscar II (Oscar Fredrik; 21 January 1829 – 8 December 1907) was King of Sweden from 1872 until his death in 1907 and King of Norway from 1872 to 1905.
Oscar was the son of King Oscar I and Queen Josephine. He inherited the Swedish and Norwegian thrones when his brother died in 1872. Oscar II ruled during a time when both countries were undergoing a period of industrialization and rapid technological progress. His reign also saw the gradual decline of the Union of Sweden and Norway, which culminated in its dissolution in 1905. In 1905, the throne of Norway was transferred to his grandnephew Prince Carl of Denmark under the regnal name Haakon VII. When Oscar died in 1907, he was succeeded in Sweden by his eldest son, Gustaf V.
Oscar II is the paternal great-great-grandfather of King Carl XVI Gustaf of Sweden. King Frederik X of Denmark is Oscar II's descendant through his son Gustaf V. King Harald V of Norway; King Philippe of the Belgians; and Henri, Grand Duke of Luxembourg are also descendants of Oscar II, all through his third son Prince Carl, Duke of Västergötland.

Helen_Moody

Helen Newington Wills (October 6, 1905 – January 1, 1998), also known by her married names Helen Wills Moody and Helen Wills Roark, was an American tennis player. She won 31 Grand Slam tournament titles (singles, doubles, and mixed doubles) during her career, including 19 singles titles.
Wills was the first American woman athlete to become a global celebrity, making friends with royalty and film stars despite her preference for staying out of the limelight. She was admired for her graceful physique and for her fluid motion. She was part of a new tennis fashion, playing in knee-length pleated skirts rather than the longer ones of her predecessors, and was known for wearing her hallmark white visor. Unusually, she practiced against men to hone her craft, and she played a relentless predominantly baseline game, wearing down her female opponents with power and accuracy. In February 1926 she played a high-profile and widely publicised match against Suzanne Lenglen which was called the Match of the Century.
Wills had a 180-match win streak from 1927 until 1933. In 1933, she beat the eighth-ranked US male player in an exhibition match. Her record of eight wins at Wimbledon was not surpassed until 1990 when Martina Navratilova won her ninth. She was said to be "arguably the most dominant tennis player of the 20th century", and has been called by some (including Jack Kramer, Harry Hopman, Mercer Beasley, Don Budge, and AP News) the greatest female player in history.
