The word "Pantechnicon" is an invented one, formed from the Greek "pan" ("all") and "techne" ("art").
 It was originally the name of a large establishment in Motcomb Street, Belgrave Square, London, opened around 1830.
 It combined a picture gallery, a furniture shop, and the sale of carriages, while its southern half was a sizable warehouse for storing furniture and other items.
 Seth Smith, originally from Wiltshire, was a builder in the early 19th century, and constructed much of the new housing in Belgravia , then a country area.
 Their clients required storage facilities and this was built on an awkward left-over triangular site with a Greek style Doric column façade, and called Pantechnicon, pseudo-Greek for "pertaining to all the arts or crafts".
 Subsequently, special wagons were designed with sloping ramps to more easily load furniture, with the building name on the side.
 The very large, distinctive, and noticeable horse-drawn vans that were used to collect and deliver the customers' furniture came to be known as "Pantechnicon vans."
 The building was largely destroyed by fire in 1874, but the facade still exists and the usefulness of the vans was by then well established and they had been adopted by other firms.
 As of 2015 the façade and the building behind it has been leased by its owner, Grosvenor Estates, to Cubitt House, a company specializing in pubs and restaurants in the Belgravia area, and is to be redeveloped into a "food and retail emporium" over six floors, including a basement and a roof-terrace, due to open in 2017.
Bloudkova velikanka (also: "Rožman/Bloudkova velikanka", "Old Bloudkova velikanka", "Large Rožman/Bloudek Hill") is a large ski jumping hill in Planica, Slovenia, opened in 1934 by Joso Gorec's initiative.
 The hill was originally constructed by Ivan Rožman who invented and first in the world used so called "snow cement".
 and unfairly named after Stanko Bloudek.
 The hill was renamed Rožman/Bloudkova velikanka posthumously to honor Rožman.
 A year after opening, Stanko Bloudek became the main constructor, improving the hill until his death and with his vision and skills made Planica world-famous and brought ski jumping/ski flying to a whole new dimension.
 As a builder, he is credited with 13 world records and in 1936 the first jump in history over 100 metres.
 Thus, a new sport was born right on this hill.
 Hill's axis and name are under national monument protection and cannot be changed.
 After almost a decade of inactivity, the hill was completely renovated and reopened in 2012.
 Right next to this one they built a brand new normal hill which replaced the old demolished one about 100 metres to the south.
William Halfpenny (active 1723–1755) was an English architect and builder in the first half of the 18th century, and prolific author of builder's pattern books.
 In some of his publications he described himself as "architect and carpenter", and his books concentrate on the practical information a builder would need, as well as addressing "gentleman draughtsmen" designing their own houses.
 They were a popular alternative to the very expensive architectural treatises by British authors such as Colen Campbell and James Gibbs, or foreigners such as Serlio or Palladio (Halfpenny published a short work "correcting" some of the latter's mistakes).
 He also wrote under the name of Michael Hoare.
James Beeching (1788 – 7 June 1858) was an English boat builder.
 He invented a "self-righting lifeboat", and designed a type of fishing boat which became characteristic of the port of Great Yarmouth in the 19th century.
 He also built ships for the smuggling trade.
Auguste Antoine Piccard (28 January 1884 – 24 March 1962) was a Swiss physicist, inventor and explorer, known for his record-breaking hot air balloon flights, with which he studied Earth's upper atmosphere and cosmic rays, and for his invention of the first bathyscaphe, "FNRS-2", with which he made a number of unmanned dives in 1948 to explore the ocean's depths.
Emil Strub (July 13, 1858 in Trimbach, Switzerland – December 15, 1909) was a Swiss builder, railway builder and inventor who invented the Strub rack system.
The FNRS-1 was a balloon, built by Auguste Piccard, that set a world altitude record.
 It was named after the Belgian Fonds National de la Recherche Scientifique, which funded the balloon.
The John Stephenson Car Company was an American manufacturer of carriages, horsecars, cable cars, and streetcars, based in New York City.
 It was founded by John Stephenson in 1831.
 John Stephenson invented the first streetcar to run on rails, building this in 1832, for the New York and Harlem Railroad.
 A reorganization in 1867 included shortening of the company's name to the John Stephenson Company.
 In the latter part of the 19th century, the company was a major builder of streetcars, constructing some 25,000 cars in the period 1876–1891 alone, including ones for export.
The Gölsdorf axle system is used on railway Gölsdorf locomotives to achieve quiet running and low wear-and-tear when negotiating curves.
 The axle system comprises a combination of fixed axles and axles that can slide transversely, all within a single, rigid locomotive frame.
 The system was invented by a young Austrian locomotive builder, Karl Gölsdorf, around the end of the 19th century.
 The first locomotive to use this principle entered service in 1897.
The following is a list of destroyers of Japan grouped by battle in which they were used.
 In naval terminology, a destroyer is a fast and maneuverable yet long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against smaller, powerful, short-range attackers.
 The Japanese torpedo boat "Kotaka" of 1885 was "the forerunner of torpedo boat destroyers that appeared a decade later".
 They were designed to Japanese specifications and ordered from the London Yarrow shipyards in 1885.
 The Yarrow shipyards, builder of the parts for the "Kotaka", "considered Japan to have effectively invented the destroyer".

Question: What was the name of the bathyscape invented by the builder of the FNRS-1?
Answer: FNRS-2
