Boris Rtcheouloff

Boris Rtcheouloff / Rcheulishvili (Georgian: ბორის რჩეულიშვილი) was a Georgian scientist, and the inventor of “videotape”. He applied for a British patent on January 4, 1927 for a technique of recording television signals on 'a magnetic record of the Poulsen telegraphone type'. Sound would be recorded in sync on the reverse side. These ideas incorporated a way to record sound or pictures by causing a strip, disc, or cylinder of iron or other magnetic material to be magnetized. He did not pay the annual renewal fee, so his patent soon lapsed.
