Frederick Dent Grant
Frederick Dent Grant was a soldier and United States minister to AustriaHungary. Grant was the first son of General of the Army and President of the United States Ulysses S. Grant and Julia Grant. He was named after his uncle, Frederick Tracy Dent. The Grant family came from a line of Scottish and Irish heritage.
His father was in the United States Army when Frederick was born in St. Louis, Missouri. The family moved as the senior Grant was assigned to posts in Michigan and New York. Frederick spent his early childhood at his paternal grandparents house while his father was stationed on the West Coast. After his fathers resignation from the army, the family lived in St. Louis and in Galena, Illinois. He attended public school in Galena until the outbreak of the American Civil War in 1861. Grants father organized a volunteer regiment and was made colonel. Frederick accompanied his father when the regiment was sent to northern Missouri, but he was sent home when it arrived. He then rejoined his father off and on at several campaigns during the war.
