Was he born von Fraunhofer or was he later granted a title?
Nobility was granted to him in 1824. (http://www.newadvent.org/cathen/06250a.htm) Stochastic 00:52, 10 March 2006 (UTC)
[edit] Recipes in the Grave
Sorry, as a non english speaker I don't understand this phrase well. You may think this is stupid question but I don't understand.
His most valuable glassmaking recipes are thought to have gone to the grave with him.
The recipes were buried with him in the grave? or it is a metaphor of some kind? --201.151.73.104 01:43, 9 February 2006 (UTC)
Metaphor: Presumably he remembered the recipes or wrote them in a place he never revealed; therefore, the recipes were lost when he died. Stochastic 00:53, 10 March 2006 (UTC)
[edit] Fraunhofer refractor =
Because of the big impact he had on telescope design, the German-language term for achromat is "Fraunhofer". Since the achromat is the most common form of refracting telescope, I think the article should highlight this invention. Note that the German Wikipeida article on Franhofer mentions "Fraunhofer-Objektiv" (Fraunhofer-Objective) in the first paragraph. I would guess other amateur observers would also be surprised not to see mention of the achromat here.
[edit] Fraunhofer diffraction?
Single slit diffraction pattern is named Fraunhofer diffraction. Why? —The preceding unsigned comment was added by Pboudreau (talk • contribs) 02:55, 13 April 2007 (UTC).
