Having a post office was vital to any community, no matter how small. Some maps would not recognize a communityâs existence if they did not have a post office. The postmaster was the go-to person for information, complaints and keeping mail moving in and out of that post office to suit the government and its customers/patrons. Nine men were appointed El Campo postmaster between 1890 and 1936. Christian Bruns was appointed March 17, 1890. A land agent for Weimar Land Co., he resigns as more people arrive and more land is sold. Eckhard Rauch is appointed July 26, 1890 (the first clerk is John Engholm). August Natho replaces Rauch on Jan. 25, 1892.
