The Telettrofono Company" was the first company in the history that was set up with the aim of exploiting the telephone, as invented by Antonio Meucci. It was set up by an agreement stipulated between:

  • Antonio Meucci, the inventor,
  • Angelo Zilio Grandi, Secretary of the Italian Consulate in New York,
  • Angelo Antonio Tremeschin, an entrepreneur in the field of civil constructions,
  • Sereno G. P. Breguglia, owner of the Cigar Stand of the Hoffman Cafe in New Street, NY, where many businessmen from the nearby New York Stock Exchange convened.

The agreement was fostered and notarized by Angelo Bertolino, a Notary Public of New York, and friend of Antonio Meucci, on 12 December 1871, a few weeks before the filing of Meucci's caveat "Sound Telegraph".

Though the company lived shortly -- two of the partners, Grandi and Tremeschin, having left the United States and the third, Breguglia, having died in the summer of the following year (1872) -- the content of the agreement reported below is enlightening as to how farsighted was Meucci's vision of the telephone.

It may be interesting to compare this agreement with the like one signed over three years later between Alexander Graham Bell and his two backers, Thomas Sanders and Gardiner G. Hubbard, that we reproduce below.
