1920s television system, diagram
1920s television system, diagram. This is the television system used by the Scottish engineer John Logie Baird (1888-1946), and first demonstrated in 1926. The transmitting apparatus is at left, and the receiving apparatus is at right. The system used a rotating mechanical disk with 50 holes in a spiral to break up the picture into areas to record and transmit. The information was transmitted using radio waves. At the receiver, the information is used to build up the image, which is observed through the holes of another rotating disc. Diagram published in Television (Dinsdale, 1928)

EDITORS COMMENTS
This print showcases the revolutionary 1920s television system designed by Scottish engineer John Logie Baird. Published in the book "Television" by Dinsdale in 1928, this diagram provides a glimpse into the early days of television technology. The image depicts two distinct apparatuses - the transmitting apparatus on the left and the receiving apparatus on the right. At its core, Baird's system utilized a rotating mechanical disk with 50 holes arranged in a spiral pattern to break down images into smaller areas for recording and transmission purposes. These fragmented pieces of information were then transmitted using radio waves. Upon reaching the receiver, this transmitted data was skillfully reconstructed to form an image that could be observed through another rotating disc containing corresponding holes. This intricate process allowed viewers to witness moving images through their televisions. With its historical significance, this diagram highlights not only Baird's groundbreaking contributions but also represents a pivotal moment in human communication and technological advancement during the early 20th century. As we gaze upon this monochrome illustration, we are transported back to an era where electromechanical ingenuity paved the way for modern-day television systems that have become an integral part of our lives today.
