Jonathan Dayton

Jonathan Dayton fought in the Revolution, signed the Constitution at age twenty-six in 1787, and rose in the 1790s to the speakership of the House of Representatives.

Born October 16, 1760 / Died October 9, 1824

On October 16, 1760, in Elizabethtown, Province of New Jersey, Jonathan Dayton was born into a prominent family headed by Elias Dayton, a Patriot officer. He studied at the College of New Jersey but left as the Revolutionary War intensified and entered military service instead. That wartime experience gave him national connections before he reached middle age.

Dayton fought at Brandywine, Germantown, and Monmouth, then joined the Constitutional Convention in 1787 as the youngest signer of the Constitution. In the 1790s he served in the House of Representatives and became Speaker, helping organize national legislative politics under the new frame of government. His later entanglement in Aaron Burr's western conspiracy ended the clean upward trajectory of his public career.

Dayton's early rise showed how quickly Revolutionary officers could move into the civilian institutions created by the Constitution. The Burr affair of 1807 also linked his name to the first great crisis over western separatism and treason in the young republic.
