Name:
Named after Heikki Allen Väyrynen (1888-1956), professor of mineralogy, Technical High School, Helsinki (Finland).
The manganese-beryllium-phosphate väyrynenite was first recognized in 1939 as a possible new mineral by Oleg von Knorring (1915-1994). However, it was first described as a new mineral by Volborth (1954), from Viitaniemi, Eräjärvi, Finland. Additional mineralogical data and new chemical analysis was given by Mrose and von Knorring (1959).
