George Sears Greene
Edit ProfileEducation
Although he entered Harvard College in 1856, he left without a degree in order to study engineering under his father.
Career
During his apprenticeship he served as assistant engineer on the Croton aqueduct, on various railroads in Cuba, and with several mining companies on Lake Superior.
In 1875 he became engineer-in-chief of the department of docks, New York City, a position which he held for twenty-two years and in which he brought to completion his most notable works. These were the design and construction of the sea wall surrounding the greater part of Manhattan Island and the building of the wharves and piers in the Chelsea Improvement on the North River between Charles Street and Twenty-third Street.
Both of these undertakings involved novel and difficult problems. The mud was deeper than any that had been previously encountered, making it impossible to drive piles to a hard bottom. To meet this situation Greene developed a radical and highly successful method of construction based upon the theory that the sustaining power of piles depends partly upon their “skin resistance, ” or the friction of the mud against their sides.
The fact that this scheme permitted a slight movement of the structures resting upon the piles led to public alarm and open criticism of his work, but its success was recognized by the experts appointed to examine it. Their report made clear the magnitude of Greene’s achievements and the brilliant manner in which he utilized cement in under-water construction. During the latter part of his career he practised in New York as a consulting engineer.
From 1911 to 1914 he was a member of the board of advisory engineers of the State Barge Canal. He was also a director, treasurer, and vice-president of the American Society of Civil Engineers.
Achievements
-
His important contributions to the theory and practise of his profession were made in connection with his topographical surveys of Westchester County, New York, and of Long Island. As a result of his experience he devised a drifting head for transits, which has proved especially valuable, and introduced other changes in surveying instruments which have since become standard.
