The Famous Bulgarians: Dimitar Tchernev


He changed the way people listen to music

This man of science began his career as an engineer at Radio Sofia, where he set out and succeeded to better the recording and broadcasting technology being used. He single-handedly made an electromagnetic recording using a celluloid medium, which was the only one of its kind outside the German innovators AGFA and BASF. Even the Americans hadn’t gonе wireless yet! After winning a competition against over 300 other candidates, Dimitar Tchernev becomes junior associate to the Bulgarian Science Academy. This is the first step in his plan to escape to the US (the political climate in Bulgaria wasn’t exactly sunshine and blue skies for this guy). After spending time in refugee camps in Germany alongside actual criminals, then moving to France, he finally attracts the right kind of attention and is invited to become assistant to the future Nobel prize winner Dr. Dennis Gabor in Stanford, Connecticut. As scientific record has it, this is where he creates the first compact tape cassette. Yeah, that’s right, tell your dad who to thank for making the mix-tape he used to swoon the ladies with. They…didn’t do that in Bulgaria, did they? Alright, well, they still listened to the Rolling Stones and the Beetles, we weren’t THAT far behind. It doesn’t end there, though. Seriously, they don’t call him a genius for nothin’! He also created the mythical cathode ray tube (used in TVs), which has the ability to record and transfer images. That same technology is used in all present-day smart phones.


The fridge that saved the children of Africa   

Just keep… inventing. Yes, that’s a Finding Nemo reference. Unlike Dory, my man Dim (no one calls him that) does not suffer from short term memory loss at all. Not only did his fully functioning super-brain come up with game-changing technology in the IT sector, but it also made history in medicine for less developed countries. Back in 1974, Dimitar Tchernev invented something revolutionary for its time – the solar-powered fridge. This incredibly innovative creation worked using the mineral zeolite, which used the sun’s energy to transform heat into ultimate coolness, oh yeah! As you can imagine, since this strong, independent fridge didn’t need no electricity to make it happen, it proved invaluable to the UN. They used it in missions across Africa in regions that had no access to electrical power to store life-saving vaccines that gave millions of children a chance for survival. Thanks, good guy Tchernev! After that incredible win for science and humanity, Saudi Arabia and Bahrain used his refrigeration technology in massive industrial warehouses, a French company began a substantial project to further develop it and the US media exploded with the news of the new invention!
