Isherwood years afterwards was elected a full academician, on the occasion of the fusion of the Academy and the Society. He joined the New York Water Color Club and the Architectural League. He belonged to the National Institute of Arts and Letters, the Century Association, the Salmagundi Club. He exhibited all over the country, served on juries, won medals, and saw paintings of his enter public museums. He was part and parcel of the art life of the United States for years, down to the day of his death at Easthampton, L. I., in 1914. Isham's diversified activity has a dual signifi- cance. It points in the first place to his living, efficient qualities as an artist, to the respect in- spired by his craftsmanship and his personality, and further it testifies to the rich experience which qualified him to write a memorable book, The History of American Painting, first pub- lished in 1905 and reissued with supplemental chapters by another hand in 1927. This book was produced as part of a series planned by Prof, John C. Van Dyke with the intention of having every contribution to it written by a practitioner of the art surveyed. Isham, as the editor of the series has said, had to be "bullied and badgered" into the composition of his volume, but when once he had undertaken it — doing most of the work in solitude in Paris — he made it the author- itative compendium in its field. Based on ex- haustive research, it is informed by the sensitive spirit of a painter, one who had a special insight into his subject, and, above all, it discloses the operation of an alert faculty of discrimination. It is sympathetic, critical, agreeable in style, a vital addition to the literature of art in the United States. [Satnttel Bttrhans, Burhans Geneal. (1894); Who's Who in America, 1914-15; Obit.

His father was a physician* The boy was sent to the Albany ( N. Y . ) Academy when he was nine, but after five years there he was returned to his home (1836) because of "serious misconduct." He was then placed in the mechanical department of the Utica & Schenec- tady Railroad under the instruction of David Isherwood Matthews, master mechanic. Upon the comple- tion of the road, he worked for a time in the of- fice of his stepfather, John Green, a civil engi- neer on the construction of the Croton Aqueduct, and then entered the employ of the Erie Rail- road, under Charles B. Stuart [g.vj, later engi- neer-in-chief of the navy, who was at that time division engineer at Susquehanna. Following this engagement, he served as engineer on the con- struction of lighthouses for the United States Treasury Department, in which connection he designed a new and efficient type of lighthouse lens and was sent to France by the department to supervise the manufacture of an order of the lenses. After a short time spent in the Novelty Iron Works, New York, acquiring the experience re- quired for admission to the newly established Engineer Corps of the United States Navy, he became in 1844 a first assistant engineer, in the original group of appointees. During the war with Mexico, he served aboard the Princeton, the first screw-propeller boat of the navy, and then aboard the Spitfire, which took part in every naval action of the war. He served at the Pensa- cola Navy Yard in 1844-45 and on board the General Taylor in 1846-47. He was promoted to the rank of chief engineer in 1848. In 1852-53 he was stationed at the Navy Department in Wash- ington, and there designed the paddle-wheels for the Water Witch, the first feathering paddle- wheels used in the United States Navy. He then served four years, 1854-58, as chief engineer on the San Jacinto, off the coast of Africa and in the East Indies. In 1859 he returned to Wash- ington, where he directed the design of a class of gunboats for the Russian government. In this year (1859) he published Engineering Precedents, in two volumes, which set forth the results of his investigations of the distribution of energy and work throughout the motive-power system of a steam vessel. These investigations, carried on in the twelve years of his active serv- ice, were the first systematic and sustained at- tempts to ascertain the distribution of energy and losses in engines and boilers, by actual measure- ments under practical, operating conditions. In 1863 and 1865 he published the first and second volumes of Experimental Researches in Steam Engineering, upon which most of his fame as an investigator and student is founded. Experimen- tal Researches consists of reports and discussions of experiments carried out aboard many ships of the navy by commissions of which Isherwood was a member and often ranking member. It in- cludes the findings of the investigation carried on aboard the U. S. S. Michigan, the results of 515
