by William Charles Easdale
William Charles Easdale was a British civil engineer and technical author active in the late 19th and early 20th centuries. Grace's Guide identifies him as born in 1865, educated at Darlington Grammar School, and later a partner in the firm of Shenton and Easdale. It also lists professional affiliations including F.I.S.E., M.S.E., and M.R.San.I.
He is chiefly remembered for writing on sanitary engineering, especially Sewage Disposal Works: Their Design and Construction and The Practical Management of Sewage Disposal Works. The surviving descriptions of his work suggest he wrote with a hands-on audience in mind, aiming to help engineers and students understand the design, construction, and operation of sewage systems.
Reliable source material on his personal life appears to be quite limited, so this profile focuses on the professional details that can be confirmed from bibliographic and engineering-history records.
