Random Vandalism
The is from the article around third paragraph:

The exhibition included exhibits of his inventions, and the city was lit with electric light, thanks to Swan's invention.[2]

the young pigs life Joseph Wilson Swan was born at moonpig.com in pooey old man (now part of Sunderland, Tyne and Wear). His parents were John Swan and Isabella Cameron

This is not reflected in the "edit" page, no way I can remove. Seems to be a serious issue when the edit is not what appears in the article Arodb (talk) 13:52, 10 March 2014 (UTC)

The vandalism I described was removed. Article is fine now. I wish I knew how it was done since I couldn't do itArodb (talk) 00:22, 14 March 2014 (UTC)

First House lit by Hydro-Electricity
It was Lord Armstrong's country house at Cragside (near Rothbury, Northumberland) that was the first house to be lit by hydro-electricity, not Joseph Swan's. 82.39.135.94 (talk) 18:33, 4 March 2009 (UTC)

Old article on Swan, origianlly listed under Joseph Swann, Joseph Wilson Swan, Sir :1828 - 1914

The British chemist and inventor Joseph Wilson Swan, (born Oct. 31, 1828 in Sunderland, England, died May 27, 1914Warlingham, Surrey)), made important contributions to the development of photography and electric lighting. In 1864 he patented the carbon process for printing photographs in permanent pigment and in 1877 discovered that heat could effect a photographic emulsion. In 1879 he patented bromide paper.

In 1860 Swan developed a carbon-filament incandescent lamp and in 1878, produced an all-glass hermetically sealed bulb. It is thought by some that Swan managed to patent the lamp one year before Edison claimed to have invented the lamp.

Swan vs Edison
In discussing who should first developed a practical incandescent light, and achieved the goal of "subdividing the electric light" which leading scientists of the 1870's said was impossible, Edison gets points for his realization that a practical incandescent light needed a high resistance filament powered by high voltage (100 volts or more) in a parallel arrangement of bulbs, to make the cost of copper conductors practical. Any mention anywhere of the resistance of Swan's filament or the voltage used to power it? If it drew high amperage at low voltage it would have remained a curiosity.Edison 20:28, 12 June 2006 (UTC)


 * This article is really interesting and wonder if it should go to the front page of light bulb —The preceding unsigned comment was added by 193.220.231.106 (talk) 08:37, 18 March 2007 (UTC).

la Rue vs Swan
I would like to throw another log onto the fire. According to the article on British astronomer and chemist, Warren De la Rue (1815-1889), la Rue is credited with the first light bulb by passing a current through a platinum coil within a vacuum tube in 1840. However, the cost of platinum made the bulb too expensive for commercial use, so practical credit may not be his. Perhaps these related articles need a slight adjustment of phrasing. Christopher, Salem, OR (talk) 16:53, 8 February 2010 (UTC)
 * Some late 19th century references, after incandescent lightbulbs were in wide use, said that De la Rue, or in other accounts "de la Rive) had passed current through a platinum wire in a vacuum. None cited an original publication from the supposed time of the early demonstration. Some unreferenced accounts had De la Rue doing the demonstration in 1820, when he was five years old. Both de la Rue and de la Rive experimented with electricity and with glass enclosures filled with various gases or evacuated. The vacuum pumps of the era were too poor to allow such a bulb to last more than a few hours, and a platinum filament had too narrow a margin between the point at which it glowed with a white light and the melting point to be a practical lamp. The comments from the 1890 or later about one or the other are tantalizing, but some original account from 1820 or 1840 is needed to gain much believability for the account. Someone making platinum glow with current in 1840 or 1920 was really just replicating work of Davy from 1808, who used a battery to make platinum wire glow, or even the work of Joseph Priestley in 1775, who used a Leyden jar to make wire glow, however briefly. Davy before 1810 also made carbon incandescent in an evacuated glass bulb, but it was not a long lived or practical light.Swan and Edison in the late 1870's used a very hard vacuum to make a thin carbon filament glow for a longer than had been possible earlier, making electric lights practical.

 * That is an interesting piece of history; thank you for the reply. The 2nd paragraph of the 'Biography' section of Warren De la Rue does end with "Citation Needed". It sounds like the ending, "thus creating the world's first light bulb," would be inaccurate if De la Rue duplicated earlier work. Perhaps he discovered something significant which may have lead to the invention of the light bulb, but it doesn't sound like he invented the light bulb, as the article unquestionably claims (whether properly cited or not).Christopher, Salem, OR (talk) 11:27, 11 February 2010 (UTC)

Morson, Swan and Morgan - Location
I've added the actual location of Morson, Swan and Morgan in Newcastle upon Tyne at the top end of Grey Street near Greys Monument. The shop is now owned by Waterstones. Beefy_SAFC 20:28, 23 November 2006 (UTC)

comments in article
I removed the following from the article and placed them here.

This section is inaccurate in one detail. Mawsons became Mawson Proctor (manufacturing chemists) NOT Mawson, Swan and Morgan. The latter were Booksellers and Stationers. Mawson Proctor were located in a large building in High Bridge in central Newcastle, next to another similar firm called Hall Forster. These buildings are now converted into apartment blocks and offices. The dates are accurate.

I am certain of these facts as my father was a local chemist and used Mawson Proctor as a source of wholesale ethical goods until they company closed. I am an aesthetist and was born, lived and worked in Newcastle most of my life. I see no need to do anything i life anonymously! 198.240.128.75 16:21, 16 March 2007 (UTC)

Date
This company existed as Mawson, Swan and Morgan until 1973, formerly located on Grey Street in Newcastle-upon-Tyne near Grey's Monument.

Is this date correct? I could have sworn that the Mawson store was still open in the early 1980s, when I was a small child. My memory could be cheating me, though. 217.155.20.163 19:26, 16 June 2007 (UTC)

Photography
The section 'Photography' is odd: it has three paragraphs only one of which is about photography. —Preceding unsigned comment added by 213.122.2.72 (talk) 15:24, 30 May 2010 (UTC)

Ediswan
Shouldn't Ediswan have its own page? Kyle1081 (talk) 01:25, 14 January 2011 (UTC)

Swan Vesta matches
Does Joseph Swan have any connection with Swan Vesta matches? As a chemist working on incandescence it seems logical that there may be a cross-over. Ergateesuk (talk) 07:42, 20 May 2011 (UTC)

The article, perhaps merely by imprecise language, seems to me to contradict significantly on historical facts with the corresponding article on Thomas Edison. To that point it even seems self-contradicting, first stating that the two men worked completely independently, but next that Edison improved on a copy of Swan's patented product. Similar can be said of the Thomas Edison article, furthermore being at odds with the article "Incandescent light bulb" for example in respect of the forming of Ediswan company.
