William Murdoch is producing coal gas from…
1794 CE
An employee of Boulton and Watt, Murdoch had first begun experimenting with the use of gas, derived from the heating of coal and other materials, for lighting in 1792.
Many believe this experimenting took place in a cave.
There is some uncertainty as to when he first demonstrated this process in practice; however, most sources identify this as between 1792 and 1794.
To use gas for practical purposes it is first necessary to develop a working method for the production and capture of the gas.
There is considerable doubt as to the date by which this process was perfected.
