Read the following passage.
The cinematograph is a motion picture film camera which also serves as a film projector and developer. It was invented in the 1890s, but there is much dispute as to the identity of its inventor.
Some argue that the device was first invented and patented as "Cinématographe Léon Bouly" by French inventor Léon Bouly on February 12, 1892. Bouly coined the term “cinematograph”, which translates in Greek to “writing in movement”. It is said that Bouly was not able to pay the rent for his patent the following year, and that the brothers Auguste and Louis Lumière bought the licence.
A more popular version of events is that Louis Lumière was the first to conceptualise the idea. The Lumière brothers shared the patent, and they made their first film, Sortie de l'usine Lumière de Lyon, in 1894.
