Question: When was the first helicopter made and flown?

Disambiguated questions and answers:
context: Heinrich Focke at Focke-Wulf was licensed to produce the Cierva C.30 autogyro in 1933. Focke designed the world's first practical transverse twin-rotor helicopter, the Focke-Wulf Fw 61, which first flew on 26 June 1936. The Fw 61 broke all of the helicopter world records in 1937, demonstrating a flight envelope that had only previously been achieved by the autogyro.

context: In 1906, two French brothers, Jacques and Louis Breguet, began experimenting with airfoils for helicopters. In 1907, those experiments resulted in the "Gyroplane No.1", possibly as the earliest known example of a quadcopter. Although there is some uncertainty about the date, sometime between 14 August and 29 September 1907, the Gyroplane No. 1 lifted its pilot into the air about for a minute. The Gyroplane No.1 proved to be extremely unsteady and required a man at each corner of the airframe to hold it steady. For this reason, the flights of the Gyroplane No.1 are considered to be the first manned flight of a helicopter, but not a free or untethered flight.

context: That same year, fellow French inventor Paul Cornu designed and built the Cornu helicopter which used two counter-rotating rotors driven by a Antoinette engine. On 13 November 1907, it lifted its inventor to and remained aloft for 20 seconds. Even though this flight did not surpass the flight of the Gyroplane No. 1, it was reported to be the first truly free flight with a pilot. Cornu's helicopter completed a few more flights and achieved a height of nearly , but it proved to be unstable and was abandoned.

Long answers:
knowledge: content: In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt, a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, aluminum, the model never lifted off the ground.

content: Steam power was popular with other inventors as well. In 1878 the Italian Enrico Forlanini's unmanned vehicle, also powered by a steam engine, rose to a height of 12 meters (39 feet), where it hovered for some 20 seconds after a vertical take-off.

content: Enrico Forlanini (13 December 1848[1] – 9 October 1930) was an Italian engineer, inventor and aeronautical pioneer, known for his works on helicopters, aircraft, hydrofoils and dirigibles.

content: Henrich Focke (8 October 1890 – 25 February 1979) was a German aviation pioneer from Bremen and also a co-founder of the Focke-Wulf company. 
wikipage: Henrich Focke

content: Focke designed the world's first practical transverse twin-rotor helicopter, the Focke-Wulf Fw 61, which first flew in June 1936. The Fw 61 had flown higher than 8,000 feet (2,400 m) at speeds of 120 miles per hour (190 km/h).

content: Turbine engines revolutionized the aviation industry; and the turboshaft engine for helicopter use, pioneered in December 1951 by the aforementioned Kaman K-225, finally gave helicopters an engine with a large amount of power and a low weight penalty.

long_answer: The first helicopter was created in 1861 by the French inventor, Gustave de Ponton d'Amécourt. However, his model never took flight. The Italian engineer, Enrico Forlanini, build an unmanned version of the helicopter in 1878 that rose to a height of 12 meters (39 feet), where it hovered for about 20 seconds after a vertical take-off. The first helicopter model to carry a pilot was in 1907. Two French brothers, Jacques and Louis Breguet, built the "Gyroplane No.1" sometime between 14 August and 29 September 1907. It lifted its pilot 2 ft into the air for about a minute. The Gyroplane No.1 proved to be extremely unsteady and required a man at each corner of the airframe to hold it steady. On 13 November 1907, another French inventor, Paul Cornu, designed and built the Cornu helicopter. It lifted its inventor off the ground and remained aloft for 20 seconds. Even though this flight did not surpass in height the flight of the Gyroplane No. 1, it was reported to be the first truly free flight with a pilot as it did not need to be held steady. Almost three decades later, German aviation pioneer and co-founder of the Focke-Wulf company, invented the Fw 61. This was the world's first practical transverse twin-rotor helicopter. It first flew on 26 June 1936 to more than 8,000 feet (2,400 m) at speeds of 120 miles per hour (190 km/h). A few years later, on 11 December 1951, turbine engines started being used in helicopters. This meant the helicopter could fly with a large amount of power and a low weight penalty.

long_answer: There are a number of helicopters, including twin-rotor, turbine-powered, manned, and truly free helicopters. The first helicopter was made in 1861, while the first helicopter flew in 1878. The first manned helicopter was made and flown at a height of 2 ft for 1 minute in 1907, and the first truly free helicopter was made and flown with a pilot on 13 November 1907. The first transverse twin-rotor helicopter was made and successfully flown on 26 June 1936, and the first turbine-powered helicopter was made and flown on 11 December 1951.
