Jonas Waldo Smith was an American civil engineer. He was responsible as engineer for the construction of the Boonton Dam, a twenty-two-mile aqueduct.
Background
He was born on March 9, 1861 in Lincoln, Massachussets, United States, the youngest son of Francis and Abigail Prescott (Baker) Smith. On his father's side he was descended from John Smith, who emigrated from England to Watertown, Massachussets, in 1636; on his mother's, from John and Elizabeth Baker, who arrived in America about 1720.
Education
His early education was received in public schools and at Phillips Academy at Andover, where he was graduated in 1881. Smith entered the Massachusetts Institute of Technology, where he received the degree of B. S. in civil engineering in 1887.
Career
As a youth of fifteen he worked on the construction of a water-supply system for his native town, and two years later became its chief engineer. From 1881 to 1883 he was employed in the engineering department of the Essex Company at Lawrence, Massachussets.
From 1887 and for three years, he worked for the Holyoke Water Power Company. In 1890 he joined the staff of Clemens Herschel, who was in charge of a great water development project in the rapidly growing district of northern New Jersey, thus beginning an association with the East Jersey Water Company and its affiliated companies, during which he served first as resident engineer (1890 - 92), then as principal assistant engineer (1892 - 1900), and finally as chief engineer (1900 - 03).
In 1903 he was engaged as chief engineer of the Aqueduct Commission of New York City and completed the construction of the new Croton Dam, at that time the largest masonry dam in the world. He was appointed in 1905 chief engineer of the New York City Board of Water Supply to develop plans and construct works for delivering five hundred million gallons of water daily from the Catskill Mountains to New York City.
Smith pushed the Catskill project through, in spite of geographical and political obstacles, within the stipulated time and at less than the estimated cost. Mayor George B. McClellan, at the dedicating exercises, declared: "The great Catskill Waterway is in itself certainly the greatest piece of water-supply engineering, if not the greatest engineering achievement of any kind, in the world. " Smith replied: "By the turn of fortune's wheel I had the privilege of leading a very loyal and enthusiastic organization imbued with a desire for service of the highest order. I pass the credit to that splendid, loyal band of enthusiastic workers".
He resigned as chief engineer in 1922, but continued as consulting engineer until his death. He also served in the same capacity for the Metropolitan Water District of Boston, Massachussets, and for many other cities in the United States, Canada, and Cuba. He was also consulting engineer on the Moffat Tunnel in Colorado.
Smith died of a heart attack at his home in New York City, when he was in his seventy-third year.
