“…in 1948 Hilger amalgamated with the well-known metrology instrument manufacturer E R Watts and the company became known as Hilger & Watts…In 1993 the company became reacquainted with an old friend. Jarrell Ash who are part of the Thermo Electron group of companies. Hilger Analytical became part of Thermo Electron in that year….In order to strengthen the Crystal Materials Group of Hilger Analytical it was decided to form Hilger Crystals Ltd. in 1997…In July 2004 Thermo Electron sold Spectra Physics to Newport Corporation who are based in the US. In order to strengthen and reinforce the Hilger brand the product line was re branded back to Hilger Crystals.. a name that is 130 years old!!” Source: http://www.hilger-crystals.co.uk/history.asp ; Adam Hilger, Ltd. ; E.

Scope and Contents:
These papers are the files of the editor of "The Amateur Scientist" section of the Scientific American from 1952 to 1975. They are arranged chronologically by date of article. The feature was started in 1952 as an expansion of "The Amateur Astronomer" section of the periodical. The papers include files of Stong's predecessor and files for articles prepared but not published before his death. The files contain correspondence with authors and readers, original illustrations, and reprints of articles.
C. L. Stong (1902-1975), an electrical engineer with the Western Electric Company from 1926 to 1962, became editor of "The Amateur Scientist" feature of the Scientific American in 1957 and held that position until his death.
