Henry Green (1834-1908) of the Preston Gas Co
1909 Obituary 
Later, he was associated with his father as an assistant, and in 1861 he was appointed Engineer and manager to the Preston Gas Company, the office of secretary being added 2 years later. He continued to discharge these duties until his death, which occurred on the 30th August, 1908, in his seventy-fifth year.
During this period of 47 years, the undertaking with which he was connected, the first of its kind in the provinces, practically quadrupled its annual output, which in 1861 stood at 134 million cubic feet. This growth necessitated considerable development and extension of the plant, and these works were designed and carried out by Mr. Green with ability and success. He also introduced several notable improvements into the process of gas-manufacture, especially in the construction of purifiers and the manufacture of sulphate of ammonia from gas liquor.
In private life he devoted himself to various local interests, served on the Commission of the Peace, was an active Freemason, and, up to the time of his last illness, an enthusiastic cyclist.
Mr. Green was elected an Associate Member of The Institution on the 1st April, 1879.
