The work on the production of "writer's boy," observed the son of Pierre Droz sixteen - Henry. The boy inherited his father's exceptional ability to mechanics and three years later he took up the construction of a new mechanical man who had on a plan to draw. The size of the painter was the same as its "big brother". In his right hand he held a pencil and drew various figures, as well as writing.
For example, it could represent a small dog and sign under the picture of "my Tutu." A portrait of Louis XV and XVI and Marie Antoinette, and now lead the admiration of visitors to the museum in Neuchâtel.
In the process, the painter stopped, as if contemplating drawn, and sometimes blew a sheet of paper with a speck of dust.
After some time, both mechanics, my father and the son of a draw, have engaged with the invention and construction of the third mechanical man - a musician. According to the complexity is much superior to their "brothers." This doll has played on the harmonium, beating his fingers on the keys. Clearly and easily managed her trills and rapid passages. Before the game, a musician examined the notes and did some preliminary hand movement. In addition, she turned her head and eyes, as if watching the position of the hands. Her chest rose and fell as if she was breathing. After graduating from the game, a musician bent her head, thanks to participants for approval. Their inventions and Pierre Henry Droz in 1774, demonstrated at the exhibition in Paris. The movements of all three mechanical people were so natural that many of the spectators were ready to consider them human beings. And only when Droz opened from the back of the complex clockwork, their creations, the audience began to believe that they face are truly works of art, rather than living creatures.
Since these machines were called androids in honor talented young inventor of mechanical men - Henry Droz.
The average person it is difficult to present a complete picture controls all the movements of the mechanical musician. But one thing is important to understand that the source of all motion described above is automatic clockwork with clockwork spring.
