<P> The United States Sanitary Commission (USSC) was a private relief agency created by federal legislation on June 18, 1861, to support sick and wounded soldiers of the United States Army (Federal / Northern / Union Army) during the American Civil War . It operated across the North, raised an estimated $25 million in Civil War era revenue (assuming 1865 dollars, $391.14 million in 2017) and in - kind contributions to support the cause, and enlisted thousands of volunteers . The president was Henry Whitney Bellows, and Frederick Law Olmsted acted as executive secretary . It was modeled on the British Sanitary Commission, set up during the Crimean War (1853 - 1856), and from the British parliamentary report published after the Indian Rebellion of 1857 ("Sepoy Rebellion"). </P> <P> Henry Whitney Bellows, (1814 - 1882), a Massachusetts clergyman, planned the USSC and served as its only president . According to The Wall Street Journal, "its first executive secretary was Frederick Law Olmsted, (1822 - 1903), the famed landscape architect who designed New York's Central Park". George Templeton Strong, (1820 - 1875), New York lawyer and diarist, helped found the commission and served as treasurer and member of the executive committee . </P> <P> In June 1861, the Sanitary Commission set up its central office inside the United States Treasury Building, just east of the Executive Mansion (now the White House), on Pennsylvania Avenue and 15th Street in central Washington, D.C. By late October 1861, the USSC Central Office and the U.S. War Department had received detailed studies and reports from the Sanitary Inspectors of more than four hundred regimental camp inspections . The rapidly crowded events of those first six months of the war displayed the sheer gravity of the situation in which the adjustment to the means and agencies were desperately needed to ensure a high health - rate in all those untrained Union Army regiments . </P>
