August Picard (1812-1872) seems to be a very interesting fellow! A detailed profile of him appears in Memoirs of American Jews 1775-1876 by J R Marcus (end of Volume I). In that book, his profile is followed by an 18-page translated (from French) excerpt from his autobiography, whose manuscript is (or was) in the American Jewish Archives. He was a soldier, lover, businessman, and father. His autobiography contains many anecdotes of his life and times. Worth looking up, good luck!
