a lawyer and author. He is known for support of Karl Wilhelm Naundorff, a Prussian watchmaker who claimed to be the real Louis XVII of France. The 1809 work "The First Book of Napoleon" by "Eliakim the Scribe" is tentatively attributed to Gruau, though Gruau would have been about fourteen years old in 1809. Between March 1839 and April 1840, Graua wrote for the periodical "The Voice of an Outlaw".
