- Frederick Graff (1775-1847) was a hydraulic engineer best known for designing Philadelphia, Pennsylvania's landmark Fairmount Water Works in the 1810s. He subsequently served as consulting engineer for water works in New York, Boston, and many other cities. After Graff's death in 1847, his son, Frederick Graff, Jr. (1817-1890), took over the role of chief engineer for the Philadelphia Water Department. Frederick Graff maps, technical drawings, and plans on Philadelphia (Pa.) water engineering projects, circa 1683-1875, consist of maps, drawings, and plans related to both the elder and younger Graff's work as water engineers. Most of the materials relate to the Fairmount Water Works, but some pertain to other water engineering projects in Philadelphia.
