First commercial lighting used manufactured gas 3 June 2005
Tom Worthington, computer consultant Visiting Fellow, Computer Science, Australian National University Respond to this E-Letter: Re: First commercial lighting used manufactured gas	Schubert and Kim wrote that the first commercial technology for lighting used natural gas. However, the first commercial gaslights used manufactured gas made from coal, not natural gas. This is reflected in the name of the first gas company formed in 1812: "Chartered Gas Light and Coke of London" (1). The "coke" mentioned in the company name is a by-product of the gas manufacturing process. References A. W.
