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 late 2000. Mindat.org now uses the MediaWiki software for its online manual.
- Robert Lavinsky (Lavinsky), a well-known mineral collector and dealer, donated his complete picture database on mindat.org to Wikimedia Commons, over 50,000 photos of minerals. The mineral lavinskyite (IMA 2012-028) was named after him.
