Carl Daenzer [In Germany, Karl] (July 17, 1820, in Odenheim – September 23, 1906, in Neckarsulm) founded the Westliche Post and was a long-time editor of the Anzeiger des Westens, two noted German-language newspapers in St. Louis, Missouri.

With the aid of friends, Daenzer started the Westliche Post, which would be a vigorous competitor with the Anzeiger for several decades to come.

He resuscitated the old concern under the name of the Neue Anzeiger des Westens, for the publication of which a company was incorporated, including William Palm, Charles Speck and others.

A statue, Naked Truth was erected in St. Louis in memory of Daenzer and two others who worked on the Westliche Post, Carl Schurz and Emil Preetorius.

In 1870, a Carl Daenzer, perhaps the same person, released 20 Eurasian tree sparrows from Germany into Lafayette Park in St. Louis.
