Notes for Frederick GRAFF
Frederick Graff was an engineer and architect. Born August 27, 1774, in Philadelphia, he was the son of Maria Shinkle and Jacob Graff, Jr., and the third in a line of American builders, contractors, and engineers. In 1797, Graff began his apprenticeship as a draftsman for the Philadelphia waterworks (often referred to as the Fairmount Waterworks), and in 1805 he became superintendent. Graff contributed to its success for the remainder of his life, remaining chief engineer until his death in 1847. His son, Frederick Graff (1817-1890), was his successor. The Philadelphia waterworks was the first steam powered waterworks in the United States. It was noted for its efficient hydraulic system developed by Graff with practically no data on which to base his calculations. Graff designed the waterworks' neo-classical buildings as well as its machinery.
