Question: What man is credited eith inventing both the Leyden jar and the Tribometer?

Passages:
A jar was an early unit of capacitance once used by the British Royal Navy.  The term originated as the capacitance of a Leyden jar.  Its value is such that one farad is jars and one jar is 1111 picofarads. Christopher Henry Gibbs (born 29 July 1938) is a British antiques dealer and collector who was also an influential figure in men's fashion and interior design in 1960s London.  He has been credited with inventing Swinging London, and has been called the "King of Chelsea" and "London's most famous antiques dealer".  The "New York Times" described him as a "man of infinite taste, judgment and experience, the one who introduced a whole generation to the distressed bohemian style of interior design." Franklin's electrostatic machine is a high-voltage static electricity generating device used by Benjamin Franklin in the mid-eighteenth century for research into electrical phenomena.  Its key components are a glass globe which turned on an axis via a crank; a cloth pad in contact with the spinning globe; a set of metal needles to conduct away the charge developed on the globe by its friction with the pad; and a Leyden jara high-voltage capacitorto accumulate the charge.  Franklin's experiments with the machine eventually led to new theories about electricity and inventing the lightning rod. A Leyden jar, or Leiden jar, is a device that "stores" static electricity between two electrodes on the inside and outside of a glass jar.  A Leyden jar typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil.  It was the original form of a capacitor (originally known as a "condenser"). The Old Jar Craftsman (독짓는 늙은이 - "Dokjinneun neulgeuni") "aka" Old Man Making a Jar is a 1969 South Korean film directed by Choi Ha-won.  It was awarded Best Film at the Blue Dragon Film Awards ceremony.  The film was selected as the South Korean entry for the Best Foreign Language Film at the 42nd Academy Awards, but was not accepted as a nominee. The Man is a graphic novella for children, written and illustrated by Raymond Briggs and published by Julia MacRae Books in 1992.  It tells the humorous story of a boy, John, who is visited by the titular Man, a minuscule human (homunculus) who arrives in the boy's bedroom unclothed and hungry.  After getting over his initial shock, the boy starts to take care of him.  The story follows their relationship over the next few days between John and 'Man', with the Man showing himself to be demanding, bossy and messy, but nevertheless a bond forms between the pair.  Their time together involves many funny and peculiar moments, such as an odd obsession with Frank Cooper's Oxford marmalade, using socks for jumpers, and a near-death collision with a marmalade jar. Franklin bells (also known as Gordon’s Bells or lightning bells) are an early demonstration of electric charge designed to work with a Leyden jar.  Franklin bells are only a qualitative indicator of electric charge and were used for simple demonstrations rather than research.  This was the first device that converted electrical energy into mechanical energy in the form of continuous mechanical motion, in this case, the moving of a bell clapper back and forth between two oppositely charged bells. Spurius Carvilius Ruga (fl.  230 BC) was the freedman of Spurius Carvilius Maximus Ruga.  He is often credited with inventing the Latin letter G.  His invention would have been quickly adopted in the Roman Republic, because the letter C was, at the time, confusingly used both for the /k/ and /g/ sounds.  For example, Ruga's own name contained this confusion: "SPVRIVS CARVILIVS RVCA" (At that time, "U" and "V" were also the same letter).  Ruga was also the first man in recorded history to open a private elementary school. Pieter van Musschenbroek (14 March 1692 – 19 September 1761) was a Dutch scientist.  He was a professor in Duisburg, Utrecht, and Leiden, where he held positions in mathematics, philosophy, medicine, and astronomy.  He is credited with the invention of the first capacitor in 1746: the Leyden jar.  He performed pioneering work on the buckling of compressed struts.  Musschenbroek was also one of the first scientists (1729) to provide detailed descriptions of testing machines for tension, compression, and flexure testing.  An early example of a problem in dynamic plasticity was described in the 1739 paper (in the form of the penetration of butter by a wooden stick subjected to impact by a wooden sphere). A tribometer is an instrument that measures tribological quantities, such as coefficient of friction, friction force, and wear volume, between two surfaces in contact.  It was invented by the 18th century Dutch scientist Musschenbroek
