Finally! Wikipedia finally has an article on Charles Porterfield Krauth, a key figure in the Evangelical Catholic branch of US Lutheranism. By rights, he should rank with John Williamson Nevin and Edward Bouverie Pusey on the list of 19th-century church reformers -- but weirdly, he is often overlooked, even by his intellectual descendants.
And by the way, he was a thoroughly Anglicized American of German extraction. His name is correctly pronounced "Krawth," not "Kraut."
