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.
[edit] 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 [1] —The preceding unsigned comment was added by 193.220.231.106 (talk) 08:37, 18 March 2007 (UTC).
[edit] 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)
[edit] 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)
