Franz Sigel
Franz Sigel (November 18, 1824 – August 21, 1902) was a German American military officer, revolutionary and immigrant to the United States who was a teacher, newspaperman, politician, and served as a Union major general in the American Civil War. His ability to recruit German-speaking immigrants to the Union armies received the approval of President Abraham Lincoln, but he was strongly disliked by General-in-Chief Henry Halleck.
