What is the Hudson Institute of Mineralogy?

The Hudson Institute of Mineralogy was formed in 2003 to offer expanded public outreach and dissemination of mineral specimens and mineralogical information at no charge to earth science teachers, students and the general public. In the ensuing dozen years since its inception, thousands of mineral specimens and significant amounts of laboratory equipment have been obtained and subsequently donated by the Institute to advance mineralogical education and awareness. The designation of Mindat.org activities as the major outreach effort of the Hudson Institute is a logical step in the development of both organizations, and it also provides Mindat.org with additional, tax exempt funding opportunities to ensure its long-term viability. The operations management of Mindat.org remains unchanged, and several Mindat managers have joined the Board of Directors of the Hudson Institute of Mineralogy.
