The Isolator was a helmet created by Hugo Gernsback in 1925 to reduce distractions.
[1][2] The Isolator was first introduced in the July 1925 edition of the American Physical Society magazine, with which Gernsback was affiliated.
[6] Gernsback re-designed the device without wood and cut white lines into the glass so users could see out of the helmet.
[6][7] However, Gernsback also noted that the helmet could only be worn for about 15 minutes at a time as the user would become drowsy.
[8][9] Gernsback then added an oxygen tank to assist the user with breathing while wearing the helmet.
