The contents of this collection reflect the varied interests of Louis Alewel, an American who participated in German-American organizations and promoted German culture. The materials include correspondence, notes, records, books and booklets, pamphlets, publications, and clippings that cover an array of cultural topics from the U.S. railrood to multiple sclerosis to elections from 1923 to 1969.

Of particular interest are the items advocating for relief for Germany after World War II. A number of correspondences and records are in connection with the Steuben Society of America, an organization for which Alewel was the secretary, and the American Relief for Germany organization. An additional highlight in the collection includes Alewel's records and documents for development of the Jeffersnn National Expansion Memorial, the area incorporating what is today the Gateway Arch in St. Louis.
