September 7, 1927 –
Philo T. Farnsworth (all of 21 years old) succeeded in transmitting an image through purely electronic means by using an image dissector on this date.
He used an “image dissector” (the first television camera tube) to convert the image into a current, and an “image oscillite” (picture tube) to receive it.
When the simple image of a straight line was placed between the image dissector and a carbon arc lamp, it showed up clearly on the receiver in another room. His first tele-electronic image was transmitted on a glass slide at his laboratory at 202 Green Street in San Francisco. He went on to have his first public demonstrate of his invention to the press a year later, on September 3, 1928.
