爱迪生发明了死人交谈记录仪吗？
Thomas Edison may have succeeded in inventing a device to record the voices of the living but he failed to pick up sounds from the dead.
According to a long-lost chapter from the American’s memoirs, which is being republished in France, the inventor of the phonograph spent some time trying to come up a way of hearing the talks of those who had died.
When the missing chapter is reproduced, French readers will be able to read the details of his trying in the magic world.
In 1870, Edison explained the sound from his phonographs -in an attempt to find a basis for his theory that the voices of the dead could be recorded. He also made a deal with an engineer, William Walter Dinwiddie, that whoever died first would try to send a message back.
Philippe Baudouin, a French radio presenter, who writes a commentary to the chapter in the new book, said: “(Edison) imagined being able to record the voice of another being, to be able to make audible that which isn’t - the voice of the dead.”
