William L. Marcy (1845–1849): Secretary of War

William Learned Marcy was born in 1786 in Worcester County, Massachusetts. He graduated from Brown University in 1808, studied the law, was admitted to the New York state bar, and opened a law practice in Troy, New York.

During the War of 1812, Marcy became an ensign in the 155th New York Regiment and distinguished himself in battle before returning home to resume his law practice. Over the next fifteen years, Marcy served as Troy’s city recorder, as an adjutant-general of the state, as comptroller of the state, and as an associate justice on the state supreme court.

In 1831, Marcy won a seat in the United States Senate but resigned it after only two years to serve as New York’s governor. He served three terms in Albany before losing the election of 1838. He was then tapped by President Martin Van Buren to join the Mexican Claims Commission.

After returning to his law practice in 1842, Marcy worked for only two years as an attorney before President James K. Polk nominated him to head the War Department. Marcy accepted the cabinet position and served as secretary of war from 1845 to 1849. Though he returned to New York following that stint, Marcy was back in Washington, D.C., within four years, this time serving in President Franklin Pierce’s cabinet as secretary of state. After leaving office in March 1857, William Learned Marcy died four months later in July 1857.
