NICOLAS-JOSEPH CUGNOT

'Nicolas-Joseph Cugnot' (26 February, 1725 – 2 October, 1804) was a French inventor. He is believed to have built the first self-propelled mechanical vehicle or automobile. This claim is disputed by some sources, however, which suggest that Ferdinand Verbiest, as a member of a Jesuit mission in China, may have been the first to build a 'car' around 1672.^[1][2]

Background

Cugnot was born in Void, Lorraine, (now ''departement'' of Meuse), France. He trained as a military engineer. He experimented with working models of steam-engine-powered vehicles for the French Army, intended for transporting cannon, starting in 1765.

The first car?

Cugnot was one of the first to successfully employ a device for converting the reciprocating motion of a steam piston into rotary motion by means of a ratchet arrangement. A small version of his three-wheeled ''fardier à vapeur'' ran in 1769. (A ''fardier'' was a massively built two-wheeled horse-drawn cart for transporting very heavy equipment such as cannon barrels).
The following year, a full-size version of the ''fardier à vapeur'' was built, specified to be able to handle 4 tons and cover 2 ''lieues'' (7.8 km or or 4.8 miles) in one hour: but which it never achieved in practice. The vehicle weighed about 2.5 tonnes tare had two wheels at the rear and one in the front where the horses would normally have been; this front wheel supported the steam boiler and was steered by means of a tiller. In 1771, this second vehicle is said to have gone out of control and knocked down part of a wall, (the first known automobile accident?). However according to Georges Ageon ^[3], the earliest mention of this occurrence is in 1801 and it does not feature in contemporary accounts.
The vehicle was reported to have been very unstable due to poor weight distribution - which would have been a serious disadvantage seeing that it was intended that the ''fardier'' should be able to traverse rough terrain and climb steep hills. Boiler performance was also particularly poor, even by the standards of the day, with the fire needing to be relit and steam raised again every quarter of an hour or so, considerably reducing overall speed.
After running a small number of trials variously described as being between Paris and Vincennes and at Meudon, the project was abandoned and the French Army's experiment with mechanical vehicles came to an end. Even so in 1772, King Louis XV granted Cugnot a pension of 600 ''livres'' a year for his innovative work and the experiment was judged interesting enough for the ''fardier'' to be kept at the Arsenal until transferred to the Conservatoire National des Arts et Métiers in 1800, where it can still be seen today.

Later life

With the French Revolution, Cugnot's pension was withdrawn in 1789, and the inventor went into exile in Brussels, where he lived in poverty. Shortly before his death, he was invited back to France by Napoleon Bonaparte and Nicolas-Joseph Cugnot returned to Paris, where he died on October 2, 1804.
