Carl August von Steinheil not the namegiver to Steinheilite?

There is a conflicting source (Exotic mineralogy: or, Coloured figures of foreign minerals: as a supplement to British mineralogy (1811) (Google eBook)) that claims Russian Count Fabian Steinheil to be the eponym of the mineral Steinheilite, not the German astronomer Carl August von Steinheil, by the manner that a deposit of the mineral wikt:dichroite (a synonym for Iolite, which is a variety of Cordierite) was found at Orajärvi, Finnish Lapland (spelled Orrayervi in the book, which ortography is consistent with old Swedish transcriptions of Finnish toponyms), at a time when Count Steinheil was the Governor-General of the Grand Duchy of Finland. | Chrishelenius (talk) 17:17, 14 November 2012 (UTC)[reply]

More than one source attributes it to the governor of Finland, and the 1811 date of that publication makes him much more likely as a namesake than this article's Steinheil. I've expanded that part of the article to state both the misattribution and the corrected attribution. The alternative would be to remove it from our article altogether, but I think this way gives us a better chance of correcting the record. —David Eppstein (talk) 05:07, 23 October 2013 (UTC)[reply]

Daguerreotype

according to this non-german source, Steinheils photographs were not of Daguerreos type: http://www.deutsches-museum.de/fileadmin/Content/data/020_Dokumente/040_KuT_Artikel/1978/2-4-20.pdf--Malzkorn (talk) 13:42, 13 February 2017 (UTC)[reply]
