Edwin Augustus Stevens
Formula:
(Ca,Na)xMg3-x(Si4O10)(OH)2
Colour:
White, Pale Yellow, Pale Brown, Pale Pink
Lustre:
Waxy, Earthy
Hardness:
2½
Specific Gravity:
2.15 - 2.57

Member of:
Smectite Group
Name:
Named after Edwin Augustus Stevens [July 28, 1795- August 8, 1868], founder of the Stevens Institute of Technology, Hoboken, New Jersey (USA). The mineral "stevensite" was named for Edwin Augustus Stevens in recognition of the high technical expertise achieved by engineering graduates of his college. Stevens was a co-founder of the Union Line Transportation Company in 1823, but which began operation in the 1830's with one of the first railroads in the USA.
