Jasper Ewing Brady was a nineteenth-century American lawyer, administrator, and politician who served as a Whig representative for Pennsylvania in the United States Congress. Born in Sunbury, Pennsylvania, in 1797, Brady initially trained in the hatter's trade and worked as a schoolteacher in Franklin County. He subsequently turned his attention to the legal profession, studying law and gaining admission to the bar in 1827, after which he established a practice in Chambersburg.
Brady's political career began with local service as the treasurer of Franklin County, followed by his election to the Pennsylvania House of Representatives, where he served from 1844 to 1845. He achieved national office upon his election to the Thirtieth Congress of the United States. Following an unsuccessful bid for reelection in 1848, Brady relocated to Pittsburgh to resume his legal practice.
During the American Civil War and its immediate aftermath, Brady contributed to the Union war effort as a clerk in the office of the paymaster general within the War Department in Washington, D.C., serving from 1861 until his retirement in 1869. He remained in Washington until his death in 1871.
