Cyril Duquet

Cyril Duquet is the inventor of the first telephone handset, or transceiver, in 1878.^[1]

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.
