The German Wiki has a different account of this:
- it states that Frauenhofer was signed up for a six year glass-cutter apprenticeship by his legal guardian after his parent's death
- it doesn't mention that the apprenticeship was especially harsh
- the prince was present at the rescue (not leading it)
- the prince gave him money which Frauenhofer used to buy a glass cutting machine and to buy out his apprenticeship contract
- Utzschneider (also present at the rescue) not the prince "enabled" his going to sunday school as well as his access to textbooks on optics.
In comparision the version here seems overly dramatic. Which one is real?
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)
The article implies that his death was related to metal poisoning. According to the book "150 Years of Spectroscopy", Fraunhofer died of tuberculosis. Any confirmation on this? VoijaRisa ( talk) 18:11, 23 November 2010 (UTC)
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)
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.
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).

Hi. Was not William Hyde Wolston the discoverer of black lines in the spectrum of the sun? This is stated in the book "Influential theories in science universe". Why is this attributed to Franhofer? Thanks. M-Shiri ( talk) 12:22, 15 February 2022 (UTC)
