Picture[edit]

The picture in the article doesn't look like James Dewar. Is it him? -- Astrochemist 22:33, 1 May 2007 (UTC)[reply]

The picture is from this site, which describes James Dewar as follows:

James was the youngest son and would not inherit the family business, so he left Stirling for London to seek his fortune. There, building on his knowledge and experience of cereal farming, he co-founded a firm called Dewar & Webb in 1872. The company soon also had branches in Portland, Oregon and the American Press of the day rather charmingly dubbed him 'King Corn'.

That doesn't sound like James Dewar the scientist, so I'm removing the picture. -- Astrochemist 13:41, 2 May 2007 (UTC)[reply]

I added a picture published in the US in 1900. - Astrochemist 01:02, 11 June 2007 (UTC)[reply]

Needs[edit]

I removed the clean-up tag. The article appears to be free from extraneous content and is reasonably well-written and organized clearly, so far as it goes. It certainly does need much more content and, perhaps, some diagrams of Dewar flasks and liquefaction equipment. The material in the External links section would be a good start. Also, see "James Dewar, his flask and other achievements" in Physics Today, volume 49, March 1996, pages 32 - 38. - Astrochemist 01:02, 11 June 2007 (UTC)[reply]

Solidification and liquefaction of hydrogen[edit]

The first liquefaction ( in 1898 ) and solidification ( in 1899 ) of hydrogen is credited to Dewar. However this account from Eclectic Magazine, June, 1878 would indicate this had been accomplished by others 23 years earlier. — The preceding unsigned comment was added by Boborama (talk • contribs) 02:59, 13 April 2007 (UTC).[reply]

Dewar did the first liquefaction and solidification of hydrogen at atmospheric pressure. Nontheless this is quite a find and should be integrated into the article. The Eclectic Magazine of 1878 can be found at Archive.org.--DrJunge (talk) 21:06, 24 January 2009 (UTC)[reply]

You'll need volume 27!--DrJunge (talk) 21:23, 24 January 2009 (UTC)[reply]

This sure looks wrong[edit]

"...in the investigation of the electrical behaviour of substances cooled to very high temperatures."

Uh, one doesn't cool things ot high temperatures, does one? 66.222.28.28 (talk) 02:45, 14 September 2009 (UTC)[reply]
