Innocenzo Manzetti

From Wikipedia, the free encyclopedia
Italian inventor (1826–1877)
Innocenzo Manzetti

Innocenzo Vincenzo Bartolomeo Luigi Carlo Manzetti[1] (Italian pronunciation:[innoˈtʃɛntsomanˈdzetti]; 17 March 1826 – 15 March 1877) was anItalianinventor born inAosta. Following his primary school studies he went to theJesuit-run Saint Bénin Boarding School and then on toTurin where he was awarded a diploma in land surveying before returning toAosta.

Inventions

[edit]

Automaton

[edit]
The flute-player (1840)

In 1840 he constructed aflute-playingautomaton, in the shape of a man, life-size, seated on a chair. Hidden inside the chair were levers, connecting rods andcompressed air tubes, which made the automaton's lips and fingers move on the flute according to a program recorded on a cylinder similar to those used inplayer pianos. The automaton was powered by clockwork and could perform 12 different arias. As part of the performance, it would rise from the chair, bow its head, and roll its eyes.

Later he managed to get his automaton to play any piece performed by a musician on an organ by muting the organ's keys and connecting them to the automaton's fingers. A complex automaton was described in the same 1865 news article that described Manzetti's telephone.[2] He also built, as a toy for his daughter, a wooden flying parrot which would beat its wings then, reportedly, rise into the air and hover for two or three minutes before settling on a shelf.

Hydraulics

[edit]

In 1855 Manzetti invented ahydraulic machine to empty water from the wells of theOllomont Mines, which were previously unworkable.[citation needed]

Steam car

[edit]

In 1864 he built asteam-powered car, some 27 years before that built inParis byLéon Serpollet. He also built the first Zamboni from that technology.[3]

Speaking telegraph (telephone)

[edit]

In 1843 Manzetti first mooted the idea of a "speaking telegraph", ortelephone, but didn't pursue the idea at the time. In 1864, to give his automaton the power of speech, Manzetti is reported to have invented his speaking telegraph –some reports state that he didn't actually get it working until the following year.[citation needed] Although he did not patent his device it was reported in Paris,[2] and likely in the press around the world.

On 22 November 1865 a description of a telephone device attributed to Manzetti appeared in theParisian newspaper,Le Petit Journal, extracted from a similar article in the Sardinia Courier ("Il Corriere di Sardegna").[2] The article very briefly wrote of an electrical telephone that could reproduce music and loudly spoken vowels with good quality, but could only produce softly spoken speech confusingly.[2] The article's author wrote:

"Manzetti transmits directly the word by means of the ordinary telegraphic wire, with an apparatus simpler than the one which is now used for dispatches. Now, two merchants will be able to discuss their business instantly fromLondon toCalcutta, announce each other speculations, propose them, conclude them. Many experiments have been made already. They were successful enough to establish the practical possibility of this discovery. Music can already be perfectly transmitted; as for the words, the sonorous ones are heard distinctly."

Earlier, on 22 August 1865,La Feuille d'Aoste had reported:[4]

"It was also rumoured thatEnglish technicians to whom Manzetti illustrated his method for transmitting spoken words on the telegraph wire intended to apply the invention on several private telegraph lines in England."

Suggestions of the allegedintellectual property theft appear unsubstantiated, as there were no historical records of English technicians or companies implementing 'speaking telegraphs' in the U.K., or elsewhere, in that period. TheUnited Kingdom did not see its first telephone demonstrations untilA.G. Bell demonstrated one of his early devices toQueen Victoria and others in 1877. Well-documented sources record that Bell first conceptualized and invented electrical telephony inCanada in July 1874,[5] and did not actually build a working model until March 1876, thus mooting the suggestion of the invention's theft from Manzetti by Bell or others although contacts between Bell andMeucci prior to Bell's patent filings are confirmed.

Miscellaneous inventions

[edit]

Other machines invented by Manzetti included:

Family

[edit]

Manzetti married Rosa Sofia Anzola in 1864. His first daughter, Maria Sofia, died in 1867 at the age of two. Manzetti himself died in Aosta on his 51st birthday, poor and largely unrecognized, one year after the death of his second and last daughter, Marina Fortunata.
