Sub-series 1. E Numbered Files, 1900-1988, undated

Arranged numerically by file number, this sub-series consists of a large, but incomplete, portion of W.L. Badger Associates’ “E” numbered subject files. The files in this sub-series were created by W.L. Badger Associates and the following corporate predecessors: W.L. Badger Consulting Chemical Engineer and Dow Chemical Company’s Consulting Engineering Division.

The E Numbered Files primarily concern the firm’s business activities. They mainly document the consultant work the firm performed for its clients and provide an extensive amount of technical information about many of the projects it worked on between the 1930s and 1980s. A handful of files regarding a proposed book by Walter L. Badger and Gordon E. Seavoy are also present in this sub-series. A few files pertaining to articles, book chapters, and papers written by Walter L. Badger and Ferris C. Standiford are also found here.

The contents of the E Numbered Files consist mainly of correspondence, blueprints, and reports. A significant amount of photocopied articles, article reprints, notes, graphs, tables, and drawing reproductions are also found in these files. Article and book chapter manuscripts, indexes, drawings, legal documents, miscellaneous printed materials, photographs, photo negatives, and photo reproductions are preserved in this sub-series as well.
