Theda Bara ( /ˈθiːdə ˈbærə/THEE-də BAR-ə; July 29, 1885 – April 7, 1955), born Theodosia Burr Goodman, was an American silent film actress – one of the most popular of her era, and one of cinema's earliest sex symbols. Her femme fatale roles earned her the nickname "The Vamp" (short for vampire).

Theodosia Burr Goodman was born in the Avondale section of Cincinnati, Ohio. Her father was Bernard Goodman (1853–1936), a prosperous Jewish tailor born in Poland. Her mother, Pauline Louise de Coppett (1861–1957), was born in Switzerland. Bernard and Pauline married in 1882.

Theda's siblings were a boy, Marque (1888–1954) and a girl, Esther (1897–1965), who also became a film actress as Lori Bara and married Francis W. Getty of London in 1920.

The origin of Bara's stage name is disputed; The Guinness Book of Movie Facts and Feats says it came from director Frank Powell, who learned Theda had a relative named Barranger. In promoting the 1917 film "Cleopatra", Fox Studio publicists noted that the name was an anagram of "Arab death", and her press agents claimed inaccurately that she was "the daughter of an Arab sheik and a French woman, born in the Sahara."

Camille Claudel (8 December 1864 – 19 October 1943) was a French sculptor and graphic artist. She was the elder sister of the poet and diplomat Paul Claudel.

Camille Claudel was born in Fère-en-Tardenois, Aisne, in northern France, the second child of a family of farmers and gentry. Her father, Louis Prosper, dealt in mortgages and bank transactions. Her mother, the former Louise Athanaïse Cécile Cerveaux, came from a Champagne family of Catholic farmers and priests. The family moved to Villeneuve-sur-Fère while Camille was still a baby. Her younger brother Paul Claudel was born there in 1868. Subsequently they moved to Bar-le-Duc (1870), Nogent-sur-Seine (1876), and Wassy-sur-Blaise (1879), although they continued to spend summers in Villeneuve-sur-Fère, and the stark landscape of that region made a deep impression on the children. Camille moved with her mother, brother and younger sister to the Montparnasse area of Paris in 1881, her father having to remain behind, working to support them.

François-Auguste-René Rodin (12 November 1840 – 17 November 1917), known as Auguste Rodin ( /oʊˈɡuːst roʊˈdæn/ oh-GOOST roh-DAN; French: [oɡyst ʁɔdɛ̃]), was a French sculptor. Although Rodin is generally considered the progenitor of modern sculpture, he did not set out to rebel against the past. He was schooled traditionally, took a craftsman-like approach to his work, and desired academic recognition, although he was never accepted into Paris's foremost school of art.

Sculpturally, Rodin possessed a unique ability to model a complex, turbulent, deeply pocketed surface in clay. Many of his most notable sculptures were roundly criticized during his lifetime. They clashed with the predominant figure sculpture tradition, in which works were decorative, formulaic, or highly thematic. Rodin's most original work departed from traditional themes of mythology and allegory, modeled the human body with realism, and celebrated individual character and physicality. Rodin was sensitive to the controversy surrounding his work, but refused to change his style. Successive works brought increasing favor from the government and the artistic community.

Lillian Diana Gish (October 14, 1893 – February 27, 1993) was an American stage, screen and television actress whose film acting career spanned 75 years, from 1912 to 1987. She was called "The First Lady of American Cinema".

She was a prominent film star of the 1910s and 1920s, particularly associated with the films of director D.W. Griffith, including her leading role in Griffith's seminal Birth of a Nation (1915). Her sound-era film appearances were sporadic, but included memorable roles in the controversial western Duel in the Sun (1946) and the offbeat thriller Night of the Hunter (1955). She did considerable television work from the early 1950s into the 1980s, and closed her career playing, for the first time, opposite Bette Davis in the 1987 film The Whales of August.

The American Film Institute (AFI) named Gish 17th among the greatest female stars of all time. She was awarded an Honorary Academy Award in 1971, and in 1984 she received an AFI Life Achievement Award.
