William Chadwell Mylne, FRS was a civil engineer and architect. He was descended from a Scottish family of masons and architects, and was the second son of Robert Mylne, who happened to be surveyor to the New River Company.
In 1804, Mylne was employed by the New River Company as assistant to his father, and upon his father's retirement in November 1810, he became chief engineer of the Company, a post he held until 1861. From 1819 he was engaged in laying out residential streets on the New River Company's property at New River Head in Clerkenwell, including Myddelton Square, Amwell Street, Inglebert Street, and River Street. Mylne later designed the gothic St Mark's Church, Myddelton Square (1826–1828), and Clerkenwell Parochial Charity Schools (1828).
1830-33 oversaw the construction of the East and West Reservoirs for the New River Company. 1852-6 he built the fortress-like (former) Pumping Station, where Myddleton Avenue meets Green Lanes.
One of his sons, Robert William Mylne, FRS (1817–90) also became an architect and geologist. Born London, died Great Amwell, Hertfordshire.
