The obscure history of the world's first synth
Built in 1901, the world’s first synthesizer has almost entirely disappeared. No recordings of the machine exist today.
Using electrical signals to create musical notes that were sent over a phone line, generated by an electric motor that doubled as an amplifier, the synthesizer known as the Thelharmonium was the very first machine to use a technique named by its inventor (Thaddeus Cahill) “synthesizing”!
What a find by the excellent magazine Popular Mechanics.
