1801-1880

British mineralogist who in 1839 developed a method using spherical trigonometry to describe how crystal faces were orientated about a crystal. A professor of mineralogy at Cambridge University, Miller used numbers derived from the intercepts of the crystal faces on a mineral's crystallographic axes to characterize the position of any crystal face. These numbers, known as Miller indices, define the position and orientation of a crystal face.
