About Schefferite
Formula:
(Ca,Mn)(Mg,Fe,Mn)Si2O6
Name:
Named in 1862 by Johann Andreas Christian Michaelson in honor of Henrik Teofilus Scheffer [December 28, 1710, Stockholm, Sweden - August 10, 1759, Stockholm, Sweden], a Swedish physician, botanist, and chemist who made studies of platinum before it was established as a new element. He was a student of Celsius and Brandt.
