He was born in the hamlet of Apalachin located in the Town of Owego, New York on April 26, 1830. Tracy was a lawyer active in Republican Party politics during the 1850s. He was a member of the New York State Assembly in 1862. He served in the Union Army during the Civil War, and commanded the 109th New York Infantry Regiment. At the Battle of the Wilderness in May, 1864, he was able to rally his men and hold the Union line. For his actions he subsequently was awarded the Medal of Honor. His citation reads: Tracy "seized the colors and led the regiment when other regiments had retired and then reformed his line and held it." Later that year, he became commandant of the Elmiraprisoner of war camp, before being appointed Colonel of the 127th Infantry, U.S. Colored Troops, on August 23, 1864. Tracy was discharged from the volunteer service on June 13, 1865. On January 18, 1867, President Andrew Johnson nominated Tracy for appointment to the brevet grade of brigadier general of volunteers, to rank from March 13, 1865, and the U.S. Senate confirmed the appointment on February 21, 1867. He resumed the practice of lawafter the war, and became active in New York state politics. He was United States Attorney for the Eastern District of New York from 1866 to 1877. In December 1881, he was appointed by Governor Alonzo B. Cornell to the New York Court of Appeals to fill the vacancy caused by the appointment of Judge Charles Andrews as Chief Judge after the resignation of Charles J. Folger. Tracy remained on the bench until the end of 1882 when Andrews resumed his seat after being defeated by William C. Ruger in the election for Chief Judge. In 1875, Tracy defended the well-known preacher Henry Ward Beecher during his highly publicized trial for adultery. Tracy was noted for his role in the creation of the "New Navy", a major reform of the service, which had fallen into obsolescence after the Civil War. Like President Harrison, he supported a naval strategy focused more on offense, rather than on coastal defense and commerce raiding. A major ally in this effort was naval theorist Captain Alfred Thayer Mahan, who had served as a professor at the new Naval War College. In 1890, Mahan published his major work, The Influence of Sea Power upon History, 1660–1783—a book that achieved an international readership. Drawing on historical examples, Mahan supported the construction of a "blue-water Navy" that could do battle on the high seas. Tracy also supported the construction of modern warships. On June 30, 1890, Congress passed the Naval Appropriations Act for Fiscal Year 1891, a measure which authorized the construction of three battleships. The first three were later named,, and. The battleship was authorized two years later. Tracy's wife and child died in a fire at their residence in Washington, DC in 1890. In the 1896 presidential election, Tracy was a presidential elector for William McKinley and Garret Hobart. After leaving the Navy Department, Tracy again took up his legal practice. In 1896 he defended New York City Police commissioner Andrew Parker from accusations of negligence and incompetence by fellow commissioner Theodore Roosevelt in a performance that significantly embarrassed Roosevelt. He also helped end the Venezuela Crisis of 1895 by assisting Venezuela in negotiating a settlement to their boundary dispute with Great Britain. Tracy was the Republican candidate to be the first Mayor of Greater New York City when the five boroughs consolidated in 1898. He came in third behind Democrat Robert A. Van Wyck and Seth Low of the Citizens' Union, winning 101,863 of the 523,560 votes cast in the election of 1897. On April 3, 1900, seven men from the International Banking and Trust Company were elected as directors of the North American Trust Company. They included president Oakleigh Thorne of the International, as well as Tracy.
