On this date in 1925 Bonnie John Logie Baird demonstrated the first live motion television transmission in Great Britain. Baird built what was to become the world’s first working television set using an old hat box, a pair of scissors, some darning needles, a few bicycle light lenses, an old tea chest, sealing wax and glue amongst other items.
Baird was a tinkerer who occasionally hit the mark with his inventions. His other ventures included:
- A glass razor blade (Unsuccessful, it was terribly brittle, but ceramic would have worked.)
- Thermal undersocks (Cotton liners which absorbed moisture, successful.)
- Video recording (To wax disk at 78 RPM, some survive.)
- Fiber optics (About 30 years before its time.)
- A radio reflection system (A harbinger of radar.)
- Infrared night object detection (Successful.)
- Radio direction finding (Finding a radiating source, successful.)
- Color television (His color wheel system was used by broadcasters as late as 1952 when RCA finally came up with a synchronization process (audio/video) entirely contained in the receiver.)
Baird developed working models of each of these concepts, but grew tired of what he had done, once the concept passed its initial stages.
