Robert Pierre André Sténuit (born 1933 in Brussels, Belgium) is a Belgian journalist, writer, and underwater archeologist. In 1962 he spent 24 hours on the floor of the Mediterranean Sea in the submersible "Link Cylinder" developed by Edwin Link, thus becoming the world's first aquanaut.

Sténuit began spelunking at the age of seventeen. He discovered diving in 1953, when he began scuba diving in flooded caves in Belgium. He subsequently became interested in speleology, and went on to spend many years exploring the Caves of Han-sur-Lesse.

Sténuit had a passion for history. At the age of 20, after reading 600 Milliards Sous les Mers by Harry Reiseberg, a work of fiction about shipwrecks and treasure diving, Sténuit left the Free University of Brussels, where he was studying political and diplomatic science in preparation for a career as a lawyer. In 1954 Sténuit began looking for the treasures of the Spanish fleet sunk in 1702 at the Battle of Vigo Bay by English and Dutch warships. He searched without success, finding only modern wrecks.

John Lethbridge (1675–1759) invented the first underwater diving machine in 1715. He lived in the county of Devon in South West England and reportedly had 17 children.

John Lethbridge was a wool merchant based in Newton Abbot who invented a diving machine in 1715 that was used to salvage valuables from wrecks. This machine was an airtight oak barrel that allowed “the diver” to submerge long enough to retrieve underwater material. In Lethbridge’s words:

It is made of wainscot perfectly round, about 6 feet in length, about 2 feet and a half diameter at the head, and about 18 inches diameter at the foot, and contains about 30 gallons; it is hooped with iron hoops without and within to guard against pressure. There are two holes for the arms, and a glass about 4 inches diameter, and an inch and a quarter thick to look though, which is fixed in the bottom part, so as to be in a direct line with the eye, two airholes upon the upper part, into one of which air is conveyed by a pair of bellows, both which are stopt with plugs immediately before going down to the bottom. At the foot part there’s a hole to let out water. Sometimes there’s a large rope fixed to the back or upper part, by which it’s let down, and there’s a little line called the signal line, by which the people above are directed what to do, and under is fix’d a piece of timber as a guard for the glass. I go in with my feet foremost, and when my arms are got through the holes, then the head is put on, which is fastened with screws. It requires 500 weight to sink it, and take but 15 pound weight from it and it will buoy upon the surface of the water. I lie straight upon my breast all the time I am in the engine, which hath many times been more than 6 hours, being frequently refreshed upon the surface by a pair of bellows. I can move it about 12 foot square at the bottom, where I have stayed many times 34 minutes. I have been 10 fathoms deep many a hundred times, and have been 12 fathom, but with great difficulty

Dr. Henry Walton "Indiana" Jones, Jr. is a fictional character and the protagonist of the Indiana Jones franchise. George Lucas and Steven Spielberg created the character in homage to the action heroes of 1930s film serials. The character first appeared in the 1981 film Raiders of the Lost Ark, to be followed by Indiana Jones and the Temple of Doom in 1984, Indiana Jones and the Last Crusade in 1989, The Young Indiana Jones Chronicles from 1992 to 1996, and Indiana Jones and the Kingdom of the Crystal Skull in 2008. Alongside the more widely known films and television programs, the character is also featured in novels, comics, video games, and other media. Jones is also featured in the theme park attraction Indiana Jones Adventure, which exists in similar forms at Disneyland and Tokyo DisneySea.

Jones is most famously played by Harrison Ford and has also been portrayed by River Phoenix (as the young Jones in The Last Crusade), and in the television series The Young Indiana Jones Chronicles by Corey Carrier, Sean Patrick Flanery, and George Hall. Doug Lee has supplied Jones's voice to two LucasArts video games, Indiana Jones and the Fate of Atlantis and Indiana Jones and the Infernal Machine, while David Esch supplied his voice to Indiana Jones and the Emperor's Tomb and John Armstrong in Indiana Jones and the Staff of Kings.

William Shakespeare (baptised 26 April 1564; died 23 April 1616) was an English poet and playwright, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His surviving works, including some collaborations, consist of about 38 plays, 154 sonnets, two long narrative poems, and several other poems. His plays have been translated into every major living language and are performed more often than those of any other playwright.

Shakespeare was born and brought up in Stratford-upon-Avon. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna, and twins Hamnet and Judith. Between 1585 and 1592, he began a successful career in London as an actor, writer, and part owner of a playing company called the Lord Chamberlain's Men, later known as the King's Men. He appears to have retired to Stratford around 1613 at age 49, where he died three years later. Few records of Shakespeare's private life survive, and there has been considerable speculation about such matters as his physical appearance, sexuality, religious beliefs, and whether the works attributed to him were written by others.
