full_context: Document 1: John Joseph Montgomery: John Joseph Montgomery (February 15, 1858 – October 31, 1911) was an American inventor, physicist, engineer, and professor at Santa Clara University in Santa Clara, California who is best known for his invention of controlled heavier-than-air flying machines.
Document 2: George Puflea: George Puflea Craciun was an early aviator. Born in modern-day Romania, he flew in the First Balkan War, in the Mexican Revolution, in the First World War and in early American and Mexican civil aviation. He was also known under his name in Spanish, .
Document 3: UC2 Kraka: Kraka, or "UC2 Kraka" was an amateur-built midget submarine completed in 2005, the first diesel-electric amateur sub in Denmark. It was built by Peter Madsen, Claus Nørregaard and several other people. The overall length was 12.6 meters and it displaced 6 tonnes. The propulsion was diesel-electric with a 16 hp diesel engine and an 8 hp electric motor. Kraka can be seen at Denmark's Technical Museum in Elsinore (aka Helsingør).
Document 4: Zadoc Dederick: Zadoc P. Dederick was an American inventor. Along with Isaac Grass he was the creator of a steam-powered humanlike robot designed to pull a cart. The invention was patented on March 24, 1868, as patent 75874, and operated through a system of levers and cranks, attached to steam-powered pistons and a boiler. The original prototype cost $2000 (about $32,487 in modern US dollars) and was built in Newark, New Jersey. Plans to produce it for $300 never went through, making this an example of an early development in steam power that was abandoned. Nonetheless, inventions such as this one spurred interest in steam power, as exemplified by novels such as "The Steam Man of the Prairies", and by many imitations and hoaxes that appeared as a result.
Document 5: Louis Blériot: Louis Charles Joseph Blériot (1 July 1872 – 1 August 1936) was a French aviator, inventor and engineer. He developed the first practical headlamp for trucks and established a profitable business manufacturing them, using much of the money he made to finance his attempts to build a successful aircraft. In 1909 he became world-famous for making the first flight across the English Channel in a heavier than air aircraft, winning the prize of £1,000 offered by the "Daily Mail" newspaper. Blériot was also the first to make a working, powered, piloted monoplane and was the founder of a successful aircraft manufacturing company.
Document 6: Félix du Temple de la Croix: Félix du Temple de la Croix (18 July 1823 – 4 November 1890) (usually simply called Félix du Temple) was a French naval officer and an inventor, born into an ancient Normandy family. He developed some of the first flying machines and is credited with the first successful flight of a powered aircraft of any sort, a powered model plane, in 1857, and is sometimes credited with the first manned powered flight in history onboard his Monoplane in 1874,
Document 7: Berkut spacesuit: The Berkut (Russian Беркут, meaning "golden eagle") is a space suit model developed to be used for extravehicular activity for the Voskhod 2 mission aboard a Voskhod spacecraft on the first spacewalk. It was developed by NPP Zvezda in 1964-1965. It was a modified SK-1 suit. It was only used by the Voskhod 2 crew.
Document 8: Kryakutnoy: Kryakutnoy (Russian: Крякутной ) or Furtzel (Russian: Фурцель ) was a fictional early 18th-century Russian inventor, who allegedly invented the hot air balloon fifty years before the Montgolfier brothers.
Document 9: Montgolfier brothers: Joseph-Michel Montgolfier (26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (6 January 1745 – 2 August 1799) were paper manufacturers from Annonay, in Ardèche, France best known as inventors of the Montgolfière-style hot air balloon, globe aérostatique. They launched the first piloted ascent, carrying Étienne. Joseph Michel also invented the self-acting hydraulic ram (1796), Jacques Étienne founded the first paper making vocational school and the brothers invented a process to manufacture transparent paper.
Document 10: Baschet Brothers: The Baschet Brothers refers to two French brothers named François Baschet (born 30 March 1920, in Paris; died 11 February 2014) and Bernard Baschet (born 24 August 1917, Paris; died 17 July 2015) who collaborated on creating sound sculptures and inventing musical instruments, such as the "Cristal Baschet". François Baschet was a sculptor and Bernard Baschet an engineer. The Baschet Brothers invented the inflatable guitar, the aluminum piano and many other experimental musical instruments. They created an "Baschet Educational Instrumentarium" for exposing young people to musical concepts. . The Baschet‘s research started in the 1950s artistic turmoil, soon turning the two brothers into the pioneers of sound sculpture, in addition to making them highly requested by musicians, composers, experimental directors.
Document 11: Jacques Charles: Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a French inventor, scientist, mathematician, and balloonist.
Document 12: Wright brothers: The Wright brothers, Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912), were two American brothers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina. In 1904–05 the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build and fly experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
Document 13: Horten brothers: Walter Horten (born 13 November 1913; died 9 December 1998 in Baden-Baden, Germany) and Reimar Horten (born 12 March 1915; died 14 March 1994 in Villa General Belgrano, Argentina), sometimes credited as the Horten Brothers, were German aircraft pilots and enthusiasts. Although they had little, if any, formal training in aeronautics or related fields, the Hortens designed some of the most revolutionary aircraft of the 1940s, including the world's first jet-powered flying wing, the Horten Ho 229.
Document 14: Tsar Tank: The Tsar Tank (Russian: Царь-танк ), also known as the Netopyr' (Нетопырь) which stands for "Pipistrellus" (a genus of bat) or Lebedenko Tank (танк Лебеденко), was an unusual Russian armoured vehicle developed by Nikolai Lebedenko (Николай Лебеденко), Nikolai Zhukovsky (Николай Жуковский), Boris Stechkin (Борис Стечкин), and Alexander Mikulin (Александр Микулин) from 1914 onwards. The project was scrapped after initial tests deemed the vehicle to be vulnerable to artillery fire.
Document 15: Jan Wnęk: Jan Wnęk (1828 – 10 July 1869) was a Polish carver of religious statues who is claimed to have constructed and flown a glider (aircraft) in the 1860s, predating the flights of Otto Lilienthal. There is a speculative "reconstruction" of Wnek's glider in the Kraków Museum of Ethnography.
