Early Life

McDowell was born in Columbus, Ohio, son of Abram Irvin McDowell and Eliza Seldon McDowell. He was a cousin-in-law of John Buford, and his brother, John Adair McDowell, served as the first colonel of the 6th Iowa Volunteer Infantry Regiment during the Civil War. Irvin initially attended the College de Troyes in France before graduating from the United States Military Academy in 1838, where one of his classmates was P.G.T. Beauregard, his future adversary at First Bull Run. He was commissioned a second lieutenant and posted to the 1st U.S. Artillery. McDowell served as a tactics instructor at West Point, before becoming aide-de-camp to General John E. Wool during the Mexican-American War. He was brevetted captain at Buena Vista and served in the Adjutant General's department after the war. While in that department he was promoted to major on May 31, 1856.

Between 1848 and 1861, McDowell generally served as a staff officer to higher-ranking military leaders, and developed experience in logistics and supply. He developed a close friendship with General Winfield Scott while serving on his staff. He also served under future Confederate general Joseph E. Johnston.
