Sub-series 1. Correspondence Files, 1952-1991, undated

Arranged alphabetically by subject, this sub-series contains Nuclide Corporation’s business correspondence files. The files in this sub-series document Nuclide’s various business activities over the course of its existence.

Correspondence with scientists, many of whom were Nuclide customers and/or users of Nuclide instruments, makes up the largest component of this sub-series. Smaller, but noticeable, amounts of Nuclide’s correspondence with investors, potential investors, investment firms, and scientific instrument companies are also found in the Correspondence Files. Several files of correspondence written by Leonard F. Herzog himself are present in this sub-series. Small amounts of correspondence with consultants, United States government agencies, and other miscellaneous individuals and entities are also preserved here.

The contents of the Correspondence Files consist mainly of letters and internal memoranda. A significant amount of accompanying materials, including, but not limited to, magazine and newspaper clippings (mostly photocopies), financial documents, legal documents, brochures, notes, and phone reports are found in this sub-series as well.
