Talk:Ludwig Carl Christian Koch

Notability
In continuation of the recent AfD, it is noteworthy that Ludwig is not in Allgemeine Deutsche Biographie, (here), even though he clearly is notable.

I have removed the following sentence: because the BEMON source itself is uncertain, quote: "or the malacologist Friedrich Carl Ludwig Koch, 1799-1852, (the son of the former?) may be the honoured person?"
 * Friedrich Carl Ludwig Koch, (1799-1852), a malacologist and possibly his brother ,

I find no other mention of this Friedrich, neither in the German wiki or in ADB,. I can find a likely Google match (name and years match) in the Darwin correspondence project, where he appears as a German mineralogist (not malacologist), here and "Koch, Friedrich Karl Ludwig and Dunker, Wilhelm. 1837. Beiträge zur Kenntniss des norddeutschen Oolithgebildes und dessen Versteinerungen. Braunschweig." here - Note the spelling Karl, not Carl. The sources are too uncertain for mentioning of Friedrich here. - Power.corrupts (talk) 08:27, 2 January 2009 (UTC)
