Presenter: Howard Heitner: “The Tilly Foster Mine”: A Classic Mineral Locality. The speaker has been collecting minerals for sixty years. He started as a field collector, collecting in New York, New Jersey, Maine and other states. Later he started purchasing specimens. He purchased several old collections and became interested in the history of mineral collecting and dealing in the United States. His other interests include fluorescent minerals and pseudomorphs. He was the president of the Stamford Mineralogical Society for many years. In his professional career he was a chemist specializing in water soluble polymers. Most of his career was spent at Cytec Industries in the development of new products used to process minerals. His post retirement mineral time has been spent finally organizing and cataloging his collection and as a volunteer at the AMNH in New York.

The Hudson valley was the center of American iron mining and production through the 1860’s.  The ore was massive magnetite.  A small iron mine in Putnam County New York worked in the late 1800’s produced many high quality crystallized mineral specimens in the relatively short time it was worked. The unique mineralogy was brought to the attention of mineralogists by chance. Among these minerals were magnetite, chondrodite, clinochlore and titanite.  Many pseudomorphs were also found there. The talk covers the geology and mineralogy of the mine.  Also covered are the history of the mine itself, the relatively modern mining methods used and the sudden end of mining in 1896.
