Day 130/365: Open! The Signage Evolution

No single person is credited as the sole inventor of the neon signs, who came up with a finished product first time. The development that took place in its evolution was gradual. It was in the year 1675 when a French astronomer, Jean Picard observed faint glow inside a mercury barometer tube he was experimenting with. At that time no one was aware of the static electricity that was causing the faint glow in the tube. Electricity was still to be discovered and so the glow was attributed to other reasons. It was in 1855 when a German physicist and glassblower, Heinrich Geissler came up with the Geissler tube. When a glass tube that contained inert gas was kept under low pressure and some electric voltage was applied then the tube started to glow.
