At the end of the war, he sold his interest in the Westliche Post and returned to Europe on account of ill health, settling in Zurich.

In 1867, Arthur Olshausen[4] acquired an interest, and in May of that year Carl Schurz became a partner and an associate of Emil Preetorius in the editorial management.

In April 1874, the paper moved to a commodious and convenient building at the corner of Fifth and Market Streets, the property having been purchased May 27, 1871, for about $90,000.

[5] At the close of the Civil War, he settled in St. Louis and became assistant editor of the Westliche Post, where he remained until his death.

Joseph Pulitzer published his first news story in the Westliche Post and worked on it as a cub reporter.

Preetorius had noticed his skill and industry at the Mercantile Library where they both spent leisure time, and city editor Louis Willich was the recipient of many aptly chosen pieces of news which Pulitzer gathered from immigrants while working as secretary at the Deutsche Gesellschaft (German Society).

On June 1, 1898, the Westliche Post consolidated with the Anzeiger des Westens, which had previously absorbed the local Tribune.

Under the consolidation, both papers, the Morning Westliche Post and the Evening Anzeiger, were issued by the German-American Press Association, the stockholders being Emil Preetorius, Carl Daenzer, Edwin C. Kehr, Charles Nagel and Paul F. Coste; John Schroers was business manager.
