This collection consists of correspondence, reports, and subject files concerning nuclear technology and radioactive waste sites connected to Mallinckrodt Chemical Works. Mallinckrodt developed a chemical process that led to the first nuclear chain reaction in 1942 and until 1966 processed uranium for nuclear weapons at plants in downtown St. Louis and Weldon Springs. The company dumped radioactive wastes at sites in St. Louis County.

The State Historical Society of Missouri collects materials documenting all aspects of Missouri history. Some of our paper and digital collections as well as older finding aids may include harmful or outdated language and could be considered offensive. SHSMO does not censor its collections, but we endeavor to be accurate and inclusive in how we describe them.
We are committed to revising and updating our descriptive language; however, with thousands of finding aids, this is ongoing and will take time. When processing new collections, we will occasionally re-use language provided by creators and former owners of the collection because it provides important context about the materials or appears in the formal names of organizations or titles of materials in the collection. In all finding aids, archivists work to contextualize the contents of manuscript collections.
