Series II. Subject Files, 1910-1946, undated

Arranged alphabetically by subject, this series contains subject files pertaining to a cross-section of Ernst Berl’s business and professional activities. Files regarding Berl’s business dealings, most notably those concerning Maurice A. Knight Company (an Akron, Ohio-based ceramics company that manufactured “Berl Saddles” under license), make up the largest component of this series. This series also contains a few files pertaining to topics of scientific interest to Berl, including, but not limited to, Berl’s method of synthesizing hydrogen peroxide. A handful of files documenting Berl’s participation in two patent dispute cases are also preserved in this series. Two files pertaining to Berl’s tenure with the Tubize Artificial Silk Factory and one small file documenting his tenure at the Carnegie Institute of Technology are preserved in this series. Three files documenting Berl’s service as a chemistry consultant to the Tennessee Valley Authority are found in this series as well.

The contents of the Subject Files consist of a variety of materials, including correspondence, reports, legal documents, and financial documents. Copies of patents, photographs, notes, article reprints, blueprints, and drawings are found in these files as well.
