Frederic Graff became the President of the American Society of Civil Engineers in January, 1885. His elevation to that distinguished office by the vote of the extended membership of this national society was accepted by him as the highest honor to which a civil engineer could aspire. His selection for that position and for the other positions of trust and confidence which he held, marked the appreciation by those with whom he was brought in contact, of the peculiar qualities with which Mr. Graff was endowed-strong common sense, excellent judgment and clearness of purpose, combined with great modesty and absence of desire for notoriety. Mr. Graff had been a member of the Society since May 7th, 1873, and took an active part in the presentation of American engineering at the Centennial Exhibition in Philadelphia in 1876, which was in charge of the Centennial Commission of the Society. The pumps and pipe service for the supply of water to the Exhibition Grounds were constructed under his direction. Mr. Graff was born in Philadelphia, May 23d, 1817, and was the son of Frederic Graff and Judith Swyer. His great-grandfather, Jacob Graff, came to Philadelphia from Germany in 1741. His grandfather, *Memoir prepared by John Bogart, M. Am. Soc. C. E. Jacob Graff, Jr., was a prosperous builder and lived in the house in Market, near 7th streets, in which Thomas Jefferson wrote the Declaration of Independence. Frederic Graff, Sr., the father of the subject of this memoir, was born in 1774, in that house. He is well known to the engineering profession as having been engaged in the construction of the city water-works of Philadelphia, first, of those in Center Square, of which he was appointed Superintendent in 1805, and afterwards as having designed and constructed the steam and water power service at Fairmount, and he continued to be the Chief Engineer of the water-works of Philadelphia until his death in 1847. Frederic Graff, his son, was made an Assistant Engineer in the Water Department in 1842, and Chief Engineer in 1847, at the death of his father, He continued to be Chief Engineer until 1856, when he resigned. In 1866, he was again elected Chief Engineer and continued to be such until 1872, then, and afterwards on several occasions, firmly declining re-election or nomination. Mr. Graff was educated in Philadelphia, and it was the desire of his father that he should enter into mercantile pursuits. He was therefore placed, after his education had been finished, in a large hardware house, but this employment was not at all congenial, and after a short time his father concluded to permit the son to follow the profession he preferred and he entered upon the study of engineering, becoming an Assistant Engineer in the Water Department in April 6th, 1842. In 1860, Mr. Graff was connected with the Port Richmond Iron Works of Philadelphia, as manager, and continued in that position for three years. In 1863 he designed and built the pipe bridge across the Wissahickon, in which the water pipe is used as a compressive member. From 1873 to 1877, he was engaged in the development of water-works and water-works machinery, in connection with Mr. Henry R. Worthington. Mr. Graff acted as Consulting Engineer and as a member of various engineering boards, on many occasions, notably as one of an expert commission in 1886, for the examination of the tunnel and other works for the water supply of Washington. He also, in company with other engineers, made trials of the pumping engines at Cambridge, Mass.; Hartford, Conn.; Providence, R. I.; Brooklyn, N. Y., and various other places. During Mr. Graff's charge of the water-works of Philadelphia, the Corinthian Avenue reservoir was built, the first turbine wheels were introduced at Fairmount, the department supplying the city with water was re-organized and the various district works combined with the principal city works; Fairmount dam was rebuilt, the Belmont reservoir on George's Hill was constructed, and the large reservoirs in the east park commenced; and the submerged main across the Schuylkill was laid. Mr. Graff, in 1851, when Chief Engineer of the Water Department of Philadelphia, presented to the City Government the suggestion of establishing a park upon the Schuylkill River and prepared plans and |
