Henry Flad
Henry Flad was a Germanborn civil engineer who served as an engineering officer in the Union Army during the American Civil War, as a railroad engineer before and during the civil war, and later as a civil engineer after the war. He helped found and was first president of the Engineers Club of Saint Louis, and in 1886 was president of the American Society of Civil Engineers.
Henry Flad was born July 30, 1824 in the Grand Duchy of Baden near the university town of Heidelberg. His father, Jacob Flad, dying within the same year, his mother Francisca Brunn Flad, very soon afterwards removed to the town of Speyer a few miles distant upon the left bank of the Rhine in the Rhine Palatinate, a province belonging to Bavaria. After passing through the preparatory schools of Speyer, young Henry entered the University of Munich, in Bavaria where he took the polytechnic course.
