(New York) (Letter asks if Kunz can get plates burnished and if it can’t be done he will come for them. Mackintosh states that he doesn’t want to invest too much capital in copper), 1885

The collection contains 17 letters, one registry return receipt, and one envelope. Two of the letters are typewritten, the remaining material is handwritten. All of the letters have a letterhead either of Lehigh University departments, American Electrochemical Society, Economic Geology and J. B. Mackintosh, E.M. All of the letters are addressed to George F. Kunz (1856-1932), a well-known gemologist and vice-president of Tiffany & Co. in response to inquiries from Kunz. The letters from Kunz making the inquiries are not in the collection. How the original letters from Lehigh personnel sent to Kunz were returned to Lehigh is not certain. According to “The Curious Lore of George Frederick Kunz” by Lawrence H. Conklin, a mineralogist, relates that in 1973 many “letters to Kunz” were offered for sale by the bookseller, Raphael Gould, trading as the American Library Service and marketing groups of “letters to Kunz” to interested parties. Perhaps during this time Lehigh University archive was offered these “letters to Kunz” specifically because of the Lehigh University notation.
