Name:
Named in honor of Pavel Vladimirovitch Jeremejev (Павел Владимирович Еремеев) (9 March 1830 - 6 January 1899, St. Petersburg, Russian Empire), Russian mineralogist, engineer, and Professor at the St. Petersburg Academy of Sciences. He collected the first specimens and suspected that they were a new mineral.
A synthetic OH-analogue is known (Stachiowak & Schreyer, 1998).
