1881 Obituary 
. . . he devoted exclusive attention, namely, that of gas manufacture and gas lighting. He was born in 1818. His father, Mr. John Evans, was one of the district engineers of the first gas company ever established, namely, the Gas Light and Coke Co (commonly called the Chartered Co), and resided at their chief station in Horseferry Road, Westminster. . . . He left it for a short time to occupy a post in the gas works at Berlin, but returned in 1839, after which time he remained with the Chartered Company till his death. In 1844 he was appointed superintendent of one of their stations in Finsbury ; and, in 1848, he removed to Westminster, occupying the position formerly held by his father.
In 1863 the late George Lowe, M. Inst. C.E., who had been the chief consulting engineer of the Company almost from its formation, retired, and Mr. Evans, having by this time gained a high reputation by the ability he had shown in the management of the works entrusted to him, became his successor. . .
