Cyrille Duquet

Who is Cyrille Duquet?

Cyrille Duquet is the inventor of the first telephone handset, or transceiver, in 1878.

Even though he is less known in the history of the invention of the telephone, the handset he created is still in use worldwide on land-line PSTN telephones. Originally working in the field of clocks and watches, he was also a passionate jewellery collector. He is credited for inventing the first telephone that had a combined system of the transmitter and the receiver in a single unit. Duquet sold his patent later for just over 2,000 dollars.
