HAYWARD, James, civil engineer, born in Concord, Massachusetts, 12 June, 1786; died in Boston, Massachusetts, 27 July, 1866. He was graduated at Harvard in 1819, and was a tutor in mathematics there for six years. In 1826 he became a professor of mathematics and natural philosophy at Harvard, but in 1829 he severed his relations with the college to enter on the practice of civil engineering. The original survey of the Boston and Providence railroad was made by him. Later he was professionally retained by the Boston and Maine railroad, projecting and having entire charge of the construction of this road, including the building of the bridge at Haverhill, and ultimately being made president of the corporation. Professor Hayward was recognized as a high authority in his profession, and was a frequent co-laborer with Loammi Baldwin, with whom and Lemuel Shaw he was se-leered, as a commission of three, to determine the water-power question that was at issue between the Boston and Roxbury water-power company and the Boston iron company. He published "Elements of Geometry, upon the Inductive Method" (Cambridge, 1829).
