# Peter Hagner

Peter Hagner (October 1, 1772 – July 16, 1850) was a clerk in the accounting office of the United States War Department, 1793–1817, and Third Auditor of the United States Department of the Treasury from 1817 to 1849; he served during the administrations of every president from George Washington to Zachary Taylor and was known as the "watchdog of the Treasury."

## Career

Hagner was born in Philadelphia, Pennsylvania on October 1, 1772.
In 1793, Hagner was appointed a clerk in the United States Department of War by President George Washington and appointed an assistant accountant in 1797, and Third Auditor of the United States Treasury by James Monroe when that office was created in 1817. He served under every administration for fifty-six consecutive years, resigning his office in 1849.
Twice by direct votes the U. S. Congress expressed its appreciation of his services in the settlement of large and important claims. This office became at one time so prominent, from the calls made upon its chief by Congress, before the institution of the court of claims, that John Randolph of Roanoke, pausing in debate for a phrase to express his sense of the influence of Nicholas I of Russia in the affairs of Europe, styled him "the great third auditor of nations." Hagner was succeeded by John S. Gallaher.

Hagner was married to Frances Randall (1787–1863), a daughter of John Randall, a Revolutionary War veteran who was Collector of the Port of Annapolis and was thrice elected Mayor of Annapolis.
