Henry Flad

Henry Flad (1823 Bavaria - 1898) was a German-born civil engineer who mostly worked in the United States.

Biography
He was educated at the College of Spire, Rhenish Bavaria, and at the University of Munich, where he graduated in 1846. He became assistant engineer on various government public works, chiefly with improvement of the Rhine, but in 1849 became a captain of the Baden revolutionary army. The failure of the revolutions of 1848/49 rendered his position in Germany insecure and he fled to the United States, where he was engaged in the engineering departments of several railroads until the outbreak of the Civil War, when he enlisted and rose to the rank of colonel of engineers.

From 1867 to 1874 he was chief assistant to James Eads on the great bridge over the Mississippi River at St. Louis. After 1877, he was president of the Board of Public Improvements of St. Louis and for many years served as member of the Mississippi River Commission.
