Talk:Warren De la Rue

Untitled
It's not very consistent, but capital D/little l seems to be favored by the more authoritative sources, like present-day EB. Stan 06:39, 23 Jan 2005 (UTC)
 * According to this article in the Antiquarian Astronomer (page 30): "The literature contains various permutations of upper and lower case D and L in the name De La Rue, but Warren always signed with upper case for both letters." Earthsound (talk) 20:59, 17 August 2017 (UTC)
 * E.g., see two publications of his from 1862 and 1877 as well as the signature section of a memorandum of agreement from 1850. Earthsound (talk) 22:14, 17 August 2017 (UTC)

Development of electric light
I found a website funded by funded by the National Science Foundation which has a timeline for the development of the light bulb, which credits WDR as a forerunner of Thomas Edison. 

Light bulb
I have just removed the following footnote from the article – from the section describing De la Rue's alleged role in the invention of the incandescent light bulb – as, although good-faith, it is clearly original research. It was originally added by Doguern in this edit of July 2017, and then extended in this edit of April 2018. "In many years of studying primary sources relating to Warren De La Rue I have never found any which make this claim. De La Rue himself seems never to have referred to it, and it appears to be erroneous.The only reference of relevance is an 1855 comment by him that he proposed to use a platinum wire ignited by a voltaic battery as a guiding light for an aerial telescope (Royal Society MM11, 27, p11; and Le Conte, David (2011): Warren De La Rue, Pioneer Astronomical Photographer, in The Antiquarian Astronomer, Issue 5, p17.)"

If there is a debate over this issue which has been reported in reliable secondary sources, please cite those sources. Wikipedia is not the place for original research. GrindtXX (talk) 17:10, 16 November 2020 (UTC)
