b. 1865
Best known for a practical early-20th-century engineering book on sewage treatment, this British civil engineer wrote with a clear eye for how public works were actually built and run. His surviving work feels grounded, technical, and closely tied to the fast-changing infrastructure needs of his time.

by William Charles Easdale
William Charles Easdale (1865–1947) is chiefly remembered today for Sewage Disposal Works: Their Design and Construction, a technical work that was later preserved by Project Gutenberg. The book focuses on the planning and building of sewage-disposal systems, suggesting he wrote for engineers, students, and others working directly with public sanitation projects.
A biographical note preserved by Grace's Guide identifies him as a civil engineer and partner in the firm of Shenton and Easdale, and lists professional affiliations including F.I.S.E., M.S.E., and M.R.San.I. That same source notes that he was born in 1865 and educated at Darlington Grammar School, which helps place him within the world of British engineering and sanitary reform in the late Victorian and Edwardian eras.
Only a small amount of easily confirmed biographical information appears to be available online, so much of his life remains lightly documented in public sources. What does come through clearly is his connection to practical civil engineering and sanitation—fields that mattered enormously as growing towns and cities needed safer, more reliable public health systems.
