Description: Benjamin Franklin Isherwood (October 6, 1822 – June 19, 1915) was an engineering officer in the United States Navy during the early days of steam-powered warships. He served as a ship's engineer during the Mexican–American War, and after the war did experimental work with steam propulsion. Rising to the rank of rear admiral, as Engineer-in-Chief of the Navy during the Civil War, he helped to found the Navy's Bureau of Steam Engineering. At the age of 22, Isherwood was appointed first assistant engineer in the Navy May 23, 1844, serving aboard General Taylor from 1846 to 1847. During the Mexican–American War, he served on the Princeton, and later was senior engineer of the Spitfire. When the Mexican–American War ended, Isherwood was assigned to the Washington Navy Yard, where he assisted Charles Stuart in designing engines and experiments with steam as a source of power for propelling ships. Throughout the 1850s, Isherwood compiled operational and performance data from steam engines in American and foreign commercial vessels and warships. He used these empirical data to analyze the efficiency of engine types then in use. In the twelve years between the Mexican–American War and the Civil War, Isherwood published 55 technical and scientific articles on steam engineering and vessel propulsion in the prestigious Journal of the Franklin Institute. In 1859 the engineer published the results of his own original thermodynamic experiments in the two-volume Engineering Precedents for Steam Machinery. Isherwood was the nation's most prolific antebellum technical writer. Isherwood went to sea during the period between the wars, serving as Chief Engineer of the steam frigate San Jacinto on a cruise of more than three years on the Asiatic Station. During this cruise he was stricken with dysentery, prompting his return to the United States. Shortly after the outbreak of the Civil War, Isherwood was appointed Engineer-in-Chief of the Navy, and so important were his services considered that the Bureau of Steam Engineering was created under his direction. When the Civil War began, the Navy had 28 steam vessels, and during the war, the number grew to 600. Isherwood conducted the design and construction of the machinery necessary to accomplish this. He designed ships that were fast enough to pursue the blockade runners. In 1863 and 1865, Isherwood published the first and second volumes of Experimental Researches in Steam Engineering, which were translated into six languages and became a standard engineering text upon which future steam experimentation was based.
