Vivianite.. Named by Abraham Gottlob Werner in 1817 after John Henry Vivian (August 9, 1785 - February 10, 1855), an English (Welsh-Cornish) politician, mine owner, and mineralogist living in Truro, Cornwall and discoverer of the mineral. (Note: Many references erroneously state that the mineral was named for J. G. Vivian, but the middle initial seems to have been a typographical error.) www.minerals.net
