JOSEPH DORNING LEIGH was born at Swinton, near Manchester, on 15th March 1822.
He was one of the first apprentices of the firm of Messrs. Nasmyth Gaskell and Co., Engineers, Bridgwater Foundry, Patricroft, near Manchester.
At the expiration of his apprenticeship he remained in the employment of the firm until April 1845, when he accepted an engagement as general manager to Messrs. Christopher Starr and Co., Engineers, Pernambuco, South America. He remained with that firm about six years, and was successfully engaged in making and erecting steam engines, sugar mills, steam dredgers, light-houses, &c.
After travelling through the States of America, and gleaning a considerable amount of information and experience, he returned to England at the end of July 1851. Here he commenced business as engineer and toolmaker, and brass and iron founder, erecting the works known as the Ellesmere Foundry, Patricroft, near Manchester. This business he carried on until the time of his death, which took place after a brief illness at his residence, Winton, Patricroft, near Manchester, on 4th December 1878, at the age of fifty-six.
He was a quick and thorough practical mechanic, and of high inventive genius.
Whilst at the Ellesmere Works he supplied machinery to several foreign governments, and also for the gold diggings and collieries in Australia.
He became a Member of the Institution in 1866.
