Television at the 1933 Chicago Worlds Fair
The 1933/34 Chicago Worlds Fair was titled “A Century of Progress.” At the Hall of Science U. A. Sanabria had a large screen television demonstration. Here is a description of the exhibit:
|
The principle of television was demonstrated in an exhibit constructed by M. L. Hayes. The process involved breaking down a picture into elements of light and dark in the transmitter, and then using the same elements to build up the picture in the receiver. In this exhibit is included a television transmitter and receiver specially designed in order to demonstrate the operations step by step. As the exhibit runs through its cycle, a series of lantern slides are projected to explain each operation." |
A recollection of the exhibit, from John N. Cox:
|
The boys' disappointment was only momentary because there were so many other marvels to see at the Chicago World's Fair of 1933. The boys repeatedly went to see one of the first television sets ever displayed in public. At each television demonstration, a person from the audience was invited on stage to stand in front of a camera and appear on television. At one show, Bob was selected and became the first person in the Cox family to appear on TV. |
