Samuel Smith (July 27, 1752April 22, 1839) was an American Senator and Representative from Maryland, a mayor of Baltimore, Maryland, and a general in the Maryland militia. He was the older brother of cabinet secretary Robert Smith. Smith served twice as President pro tempore of the United States Senate, first from 1805 to 1808 and later from 1828 to 1831. Biography Samuel Smith was born in Carlisle in the Province of Pennsylvania. His grandfather, also named Samuel Smith (1698–1784), was born in Ireland and settled in the Province of Maryland. Smith moved with his family to Baltimore, Maryland, in 1759. He attended a private academy, and engaged in mercantile pursuits until the American Revolutionary War, at which time he served as captain, major, and lieutenant colonel in the Continental Army. Prior to the war, as a young captain, he was sent to Annapolis to arrest Governor Eden and seize his papers. On September 23 with Philadelphia on the verge of capture, Washington sent Smith, then a Lieutenant Colonel of the 4th Maryland Regiment with a detachment of Continentals into the fort on Mud Island on the Delaware River. Smith's force numbered 200 soldiers plus Major Robert Ballard of Virginia, Major Simeon Thayer of Rhode Island, and Captain Samuel Treat of the Continental Artillery. However, another account stated that Thayer did not reach Fort Mifflin until October 19. With the British army closing in on Philadelphia, the small force had to reach Fort Mifflin by a circuitous route. On the last leg of their journey, reinforcements for Mud Island had to be ferried across the Delaware from Red Bank, New Jersey under the protection of the Pennsylvania Navy river flotilla commanded by John Hazelwood. The fort was eventually overwhelmed by weeks of British bombardment and was abandoned. After his service in the war, Smith engaged in the shipping business. Colonel Smith was admitted as an original member of The Society of the Cincinnati of Maryland when it was established in 1783. He went on to serve as the vice president (1804-1828) and president of the Maryland Society (1828-1839), serving in the latter capacity until his death. From 1790 to 1792, Smith was a member of the Maryland House of Delegates. At the time of the threatened war with France in 1794, he was appointed brigadier general of the Maryland militia and commanded Maryland's quota during the Whiskey Rebellion. Smith entered into
