The Soyuz programme is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon.

Marguerite Durand (1864–1936) was a French stage actress, journalist, and a leading suffragette. In 1888, she gave up her career in the theatre to marry an up-and-coming young lawyer, Georges Laguerre. A friend and follower of the politically ambitious army general Georges Ernest Boulanger, her husband introduced her to the world of radical populist politics and involved her in writing pamphlets for the Boulangist movement. Her newspaper, La Fronde, was founded in 1897 to pick up where Hubertine Auclert's La Citoyenne left off. She had a pet lion, and her collected papers are now housed in the Bibliothèque Marguerite Durand in Paris. This photograph of Durand was taken in 1910.

Social grooming among primates plays a significant role in animal consolation behavior in which individuals engage in establishing and maintaining alliances through dominance hierarchies. It cements pre-existing coalitions, and is used for reconciliation after conflicts. Primates groom socially in moments of boredom as well, and the act has been shown to reduce tension and stress. This video clip depicts Japanese macaques grooming each other at the Jigokudani Monkey Park in Japan.

Thérèse is an opera in two acts by Jules Massenet to a French-language libretto by Jules Claretie. Set during the French Revolution, the plot concerns Thérèse, who is torn between duty and affection, between her husband André Thorel, a Girondist, and her lover, the nobleman Armand de Clerval. Although she had decided to follow her lover into exile, when her husband is being led to execution she shouts Vive le roi! (Long live the king!) amid the frenzied crowd and is dragged to her husband's side and marched to the guillotine. The opera first performed in Monte Carlo in 1907, and is among Massenet's lesser-known works.

Iris Calderhead (1889–1966) was a suffragist and organizer in the National Woman's Party. She became involved in the women's suffrage movement in 1915 after meeting Doris Stevens and Lucy Burns, leaders of the Congressional Union, in New York City. She spent the next several years traveling around the US, mobilizing support for a federal constitutional amendment guaranteeing women's right to vote. She was arrested twice in 1917, first for displaying a banner during a visit by President Woodrow Wilson and then for picketing the White House. The Nineteenth Amendment guaranteed women's right to vote in the United States in 1919, but Calderhead's activism continued as she campaigned for the same rights internationally.
