 During these Austrian years, Schlegel was, among other things, the editor of an anti-Napoleonic newspaper, founder of two other prominent journal projects (the Deutsches Museum and Concordia) and an apparently popular public lecturer on a wide range of topics. Metternich asked him in 1813 to draw up proposals for a future German constitution, and Schlegel served (until he was recalled) as first secretary of the Austrian legation to the Diet of Frankfurt. He died in Vienna in January 1829.
