Gas lighting was a popular way to get light source in cities and suburbs before electrical lighting was invented. Gas lighting was a process of getting light source by burning coal gas or natural gas. Gas lighting provides artificial light source to whomever and whenever they needed. William Murdoch was the first one who discovered that gas can be used as a flammable for lighting. In the 1790s, he experienced with various materials and concluded that coal gas worked the best. After the gas lighting became a successful process in getting artificial light sources, streets had gas lamps, which decreased the crime rate and built safer towns. Another impact of the gas lighting was that it allowed factories to work even longer hours. Since workers could now work twenty four hours, productions were increased. Gas lighting was brighter than candles and oil burning and it lasted much longer. Because of this, learning and literacy improved.
