History of Mindat.org
Mindat was started in 1993 as a personal database project by Jolyon Ralph. He then developed further versions as a Microsoft Windows application before launching a community-editable database web site in October 2000.[1]
Mindat.org is now part of the Hudson Institute of Mineralogy, a 501(c)(3) not-for-profit educational foundation incorporated in the state of New York.
Jolyon Ralph was awarded the Mineralogical Society of America's Distinguished public service medal in 2011 for his work on Mindat.org.[2]
