Some context: Jacques-Yves Cousteau  (French: [Zak iv kusto]; commonly known in English as Jacques Cousteau; 11 June 1910 - 25 June 1997) was a French naval officer, explorer, conservationist, filmmaker, innovator, scientist, photographer, author and researcher who studied the sea and all forms of life in water. He co-developed the Aqua-lung, pioneered marine conservation and was a member of the Academie francaise. Cousteau described his underwater world research in a series of books, perhaps the most successful being his first book, The Silent World: A Story of Undersea Discovery and Adventure, published in 1953.
In 1946, Cousteau and Tailliez showed the film Epaves ("Shipwrecks") to Admiral Lemonnier, who gave them the responsibility of setting up the Groupement de Recherches Sous-marines (GRS) (Underwater Research Group) of the French Navy in Toulon. A little later it became the GERS (Groupe d'Etudes et de Recherches Sous-Marines, = Underwater Studies and Research Group), then the COMISMER ("COMmandement des Interventions Sous la MER", = "Undersea Interventions Command"), and finally more recently the CEPHISMER. In 1947, Chief Petty Officer Maurice Fargues became the first diver to die using an aqualung, while attempting a new depth record with the GERS near Toulon.  In 1948, between missions of mine clearance, underwater exploration and technological and physiological tests, Cousteau undertook a first campaign in the Mediterranean on board the sloop Elie Monnier, with Philippe Tailliez, Frederic Dumas, Jean Alinat and the scenario writer Marcel Ichac. The small team also undertook the exploration of the Roman wreck of Mahdia (Tunisia). It was the first underwater archaeology operation using autonomous diving, opening the way for scientific underwater archaeology. Cousteau and Marcel Ichac brought back from there the Carnets diving film (presented and preceded with the Cannes Film Festival 1951).  Cousteau and the Elie Monnier then took part in the rescue of Professor Jacques Piccard's bathyscaphe, the FNRS-2, during the 1949 expedition to Dakar. Thanks to this rescue, the French Navy was able to reuse the sphere of the bathyscaphe to construct the FNRS-3.  The adventures of this period are told in the two books The Silent World (1953, by Cousteau and Dumas) and Plongees sans cable (1954, by Philippe Tailliez).

Some context: Kenneth Charles Loach (born 17 June 1936) is an English director of television and independent film. His socially critical directing style and socialist ideals are evident in his film treatment of social issues such as poverty (Poor Cow, 1967), homelessness (Cathy Come Home, 1966) and labour rights (Riff-Raff, 1991, and The Navigators, 2001). Loach's film Kes (1969) was voted the seventh greatest British film of the 20th century in a poll by the British Film Institute. Two of his films, The Wind That Shakes the Barley (2006) and I, Daniel Blake (2016) received the Palme d'Or at the Cannes Film Festival, making him the ninth filmmaker to win the award twice.
Loach first joined the Labour Party from the early 1960s. In 1980s, he was in the Labour Party because of the presence of "a radical element that was critical of the leadership", but Loach had left the Labour Party by the mid-1990s after being a member for 30 years. During the 1960s and 1970s, he was associated with (or a member of) the Socialist Labour League (later the Workers Revolutionary Party), the International Socialists (later the Socialist Workers Party or SWP) and the International Marxist Group.  Involved in Respect - The Unity Coalition from its beginnings in January 2004, and stood for election to the European Parliament on the Respect list in 2004. Loach was elected to the national council of Respect the following November. When Respect split in 2007, Loach identified with Respect Renewal, the faction identified with George Galloway. Later, his connection with Respect ended.  Loach supported the Trade Unionist and Socialist Coalition in the London Assembly election, 2012. With the support of the activist Kate Hudson and academic Gilbert Achcar, Loach launched a campaign in March 2013 for a new left-wing party which was founded as "Left Unity" on 30 November. Loach gave a press conference during the launch of Left Unity's manifesto for the 2015 general election.  Together with John Pilger and Jemima Khan, Loach was among the six people in court who offered surety for Julian Assange when he was arrested in London on 7 December 2010. The money was forfeited when Assange skipped bail to seek asylum in the Embassy of Ecuador, London.
