Tightrope walking in the context of Slacklining

Philippe Petit (French pronunciation: [filip pəti]; born 13 August 1949) is a French highwire artist who gained fame for his unauthorized highwire walks between the towers of Notre-Dame Cathedral in Paris in 1971 and of Sydney Harbour Bridge in 1973, as well as between the Twin Towers of the World Trade Center in New York City on August 7, 1974.

Since then, Petit has lived in New York, where he has been artist-in-residence at the Cathedral of St. John the Divine, another site of his aerial performances. He has done wire walking as part of official celebrations in New York, across the United States, and in France and other countries, as well as teaching workshops on the art. In 2008, Man on Wire, a documentary directed by James Marsh about Petit's walk between the towers, won numerous awards including the 2009 Academy Award for Best Documentary Feature. The Walk, a film based on Petit's walk, was released in September 2015, starring Joseph Gordon-Levitt as Petit and directed by Robert Zemeckis. Petit was also the subject of a children's book and an animated adaptation of it, released in 2005.

Philip Astley (8 January 1742 – 20 October 1814) was an English equestrian, circus owner, and inventor, regarded as being the "father of the modern circus". Modern circus, as an integrated entertainment experience that includes music, domesticated animals, acrobats, and clowns, traces its heritage to Astley's Amphitheatre, a riding school that Astley founded in London following the success of trick-riding displays given by him and his wife Patty Jones in 1768. Astley's first competitor was equestrian Charles Hughes, who had previously worked with Astley. Together with Charles Dibdin, a famous author of pantomimes, Hughes opened a rival amphitheatre in London, which Dibdin called the Royal Circus and Equestrian Philharmonic Academy.

Astley and his wife Patty put on their first public show on Easter Monday, 4 April 1768. extending the equestrian performance with exhibitions of warlike sabre-work and sword-play. The initial performances were done in the open air at Ha'penny (= Halfpenny) Hatch, a field in Lambeth, London, near the present site of Waterloo railway station. The Astleys also performed at other locations in London. Astley performed his stunts in a circular arena, though Astley never used the title of 'circus' for his shows. Astley's 'Ride' (he also called it 'the Circle') was a ring 65 ft (19 metres) in diameter. Later, the size evolved to become standardised at 42 feet (13 metres) which is the size used by circuses ever since. Leasing more permanent premises at Westminster Bridge from 1769, he improved conditions for audiences with a covered stands. The performances themselves, however, were still performed in the open. In 1770 he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between acts. and so initiated the format which we now know as a 'circus' and which has since spread to many countries.

Vander Clyde Broadway (December 19, 1899 – August 5, 1973), stage name Barbette, was an American female impersonator, high-wire performer, and trapeze artist born in Texas. Barbette attained great popularity throughout the United States but his greatest fame came in Europe and especially Paris, in the 1920s and 1930s.

Barbette began performing as an aerialist at around the age of 14 as one-half of a circus act called The Alfaretta Sisters. After a few years of circus work, Barbette went solo and adopted his exotic-sounding pseudonym. He performed in full drag, revealing himself as male only at the end of his act.

Jolly Jumper is a horse character in the Franco-Belgian comics series Lucky Luke, created by Belgian artist Morris. Described as "the smartest horse in the west" and able to perform tasks such as chess-playing and tightrope walking, Jolly Jumper accompanies his cowboy in their travels across the Wild West, and delivers frequent quips.

Much like Lucky Luke, the English-language alliterating Jolly Jumper is rarely renamed in translated versions. Although in the Greek version of the series, Jolly Jumper is female and is called "Dolly". In the Turkish version the character is called "Düldül".
