Maybe you blame your smartphone or your open office for the fact that you can’t concentrate at work. But distraction isn’t exactly a new problem: In the 1920s, Hugo Gernsback published a design for a creepy-looking helmet that blocks out sound and vision so someone can focus on their work. As a writer, editor and inventor, he had a lot to do and no time for distractions. And yet, they lurked everywhere he looked. So, he created something he called “The Isolator”.
Later, the inventor added an oxygen tank when it was found wearers were getting sleepy inside the quiet, dark and – as it turns out – carbon-dioxide-filled helmet.
