thread_title:  What did he die of 

message: From the French Wikipedia version of this article:
Son nom s'écrit aussi L'Hospital. Contrairement à ce qu'on pourrait croire, l'accent circonflexe n'est pas un anachronisme : si son livre ne comporte pas de nom d'auteur, son ami Varignon, dans les compléments qu'il publia au livre (1725), écrit toujours son nom avec l'accent circonflexe, et dans l'encyclopédie de D'Alembert-Diderot, c'est « L'Hopital » qu'on trouve, sans accent ni s.
My translation:
His name is also written as "l'Hospital."  Contrary to what one might think, the circumflex accent is not an anachronism: even though his book did not carry his name, his friend Varignon, in the supplements that he published for the book (1725), always wrote his name with the circumflex accent, and in the encyclopedia of D'Alembert-Diderot, it is "L'Hopital" that one finds, without either the accent or the s.
What is the truth about the spelling of his name and the origin of the differing versions?
:: the current description in the (english) article is correct (he spelled himself with a (silent) s, but the french spelling rules have changed since his time).--84.174.207.73 (talk) 21:53, 7 January 2009 (UTC)
thread_title:  Spelling: French version 

message: I totally don't understand what this person talks about.
1. It is wrong. If you don't require the numerator to converge at all, then what about cos x/x when x -> infinity? The limit is of course 0, but you gent divergent function if you differentiate both the numerator and the denominator.
2. It is out of place in the formatting. It looks like it mean to be some kind of talk, but it is in the main page, below "See also".
3. Any detailed description of the theorem should go the page of L'Hôpital's rule.
If there is no reaction to this, I'll remove that edit.

thread_title:  What is this comment at the end of the article? 

message: Speaking of which, can we get French and Anglicized pronunciations of his name in the article? I'd do it myself if I only had a clue. --/ˈwɪkiwaʊ/. 02:48, 19 October 2009 (UTC)
thread_title: Pronunciation

message: This article appears to have been very poorly written and contains little besides repeated assertions about l'Hôpital's rule. I've spent quite a bit of time tidying it up, but, frankly, it would have been better just to rewrite it from scratch using a reputable source. In any case, issues of proper target to link calculus seem infinitesimal compared to the Gargantuan task of creating a reasonable biographical article. Arcfrk (talk) 05:17, 21 July 2010 (UTC)

text: The claim that his father was Duc d'Orléans: that seemed a bit too far-fetched to be true when I first put it in, but I forgot to double-check. The name of the l'Hôpital's estate, Oucques, is misspelt there, too. By the way, here is an article about l'Hôpital written by Abraham Robinson. I haven't used it in writing my revision, but do you think it should be added as a reference? Arcfrk (talk) 01:19, 23 July 2010 (UTC)
replies: text: Thanks for the link, I did not know about it.  It has valuable information about the book "Analyse etc".  Some of it should be added at the wiki page for the book.  Note that Robinson spells the title without the definite article.  The second edition, which is online, spells it the same way.  Later editions added the definite article, as in "l'analyse".  Has anyone seen the first edition?  There seems to be a systematic error in the literature (one historian copying from the earlier one) in citing the title with the definite article.  Unless, of course, the first edition also had the l'. Tkuvho (talk) 03:48, 23 July 2010 (UTC)

text: You are correct about the book's title, good catch! And I see that you have already corrected the title of the article about the book by removing the article from the title of the article which is the title of the book (ugh!) |15px Arcfrk (talk) 06:42, 23 July 2010 (UTC)
replies: text: Thanks.  It would be good for someone to get around to adding the information from the Dictionary of scientific biography to the book page.  Also, the controversy involving l'H and Bernoulli is reported in contradictory ways on the two biography pages.  Should the whole thing be moved to the book page? Tkuvho (talk) 11:49, 23 July 2010 (UTC)

text: I think that some description of the controversy is warranted at both bio pages. "Signed a contract" (at Bernoulli page) is misleading, but the short paragraph there is easy enough to fix (and I scratched my head trying to understand how "L'Hôpital controversy" is a part of his "Scientific contribution" — one might think that besides quarreling with l'Hôpital, he accomplished little else).

thread_title:  Quality assessment 

message: There are a number of uncited claims in the Calculus Textbook section (basically all of it is uncited). I have added "Citation needed" markers in the last two sentences of that section because I think that those claims are basically undisprovable. Rest is factual, but does not lead to a source of any sort. This section, if cleaned up and referenced, would present a breve but clear account of the chronology of l'Hopital's books.  — Preceding unsigned comment added by 128.178.125.49 (talk) 13:56, 24 February 2014 (UTC)

message: The quality of the portrait in this article is not up to the standards of Wikipedia. It is grainy, low resolution, and has evidence of severe compression.— Preceding unsigned comment added by 96.228.248.198 (talk) 21:54, 8 January 2016 (UTC)
