W. B. (William Benjamin) Gregory

William Benjamin Gregory (1871–1945) was an American engineer known for technical writing on hydraulics, pumping plants, drainage, and related civil engineering subjects. Records tied to his published work show that he wrote government and professional material on pump testing and drainage systems, and he is also associated with the book Hydraulic Engineering.

Contemporary reference material describes him as a specialist in hydraulic engineering and notes that he received the Worcester Reed Warner Medal in 1940 for distinguished work in the field. A scientific news notice also identifies him as professor emeritus of experimental engineering and hydraulics at Tulane University, suggesting that teaching as well as consulting formed an important part of his career.

For audiobook listeners, he is best understood not as a literary author in the usual sense, but as a clear technical explainer. His surviving books belong to the world of early twentieth-century engineering, where careful measurement, field testing, and practical design mattered most.
