- Honoured by Napoleon and (unexpectedly) by the Czar of Russia, friend of Wordsworth, Coleridge and Lord Byron, Sir Humphry Davy was one of the brightest stars in the European firmament.
Discoverer of sodium, potassium and five other elements as well as the anaesthetic properties of nitrous oxide, inventor of the Davy miners' lamp and of the technique of cathodic protection, he packed more action and achievement into his short life - he was buried in Geneva not long after his fiftieth birthday - than most scientists before or after him, even those who outlived him by several decades. Much admired by Berzelius, sometimes criticized by his fellow countrymen, he used to say that his greatest discovery was Michael Faraday.
Sir John Meurig Thomas, Honorary Professor at the Department of Materials Science and Metallurgy, University of Cambridge, traced Davy's path from his lowly origins in Cornwall to the pinnacles of international fame.
Excellent - thanks much for sharing.
Very informative talk, thanks to RSC.
Very enjoyable - two very significant scientists closely involved. There is some confusion about which elements Davy discovered but his name is mentioned in at least 9 element discovery narratives. This alone would assure his fame in any other country but apparently we only remember the lamp?
Michael Faraday would never have become a scientist if Davy hadn't hired him. His legacy is huge.
Fourier was on the expedition that discovered the Rosetta Stone.
I'm having difficulty locating a record of that book "Conversations in Chemistry for Young Ladies." I realize it is probably not in print, but if there are any details or digital records of it, it would be very useful for a presentation I am preparing.

Sparing patients pain meant that care and neatness could replace speed as the goal of surgery, and a larger range of operations could be done.
OSK is about physics.

The picture doesn't match the soundtrack, at all.
Of course it would churlish to point out that Davey was a Cornishman and revered as such in Penzance it's a pity a Welshman has so little tact when it concerns the acknowledgement of a individual from another Celtic country. Perhaps he exhibited a unique Cornish perspective that was nether English, Welsh, Scotish, Irish or Manx.
Did not, this very mans work, inspire the fantastical writings of Jules Verne, his definate denial of the centrailized fire theory of the earth, that holds today? I think thats why his life was ended in Geneva.
Why does it look like the woman is speaking with an old man’s voice?
John - da iawn. Gorffwys mewn heddwch ;)
Exuse me, gendlemens, Michael Faraday was more famus, more beautiful and kind than Davy...Ok, Davy was a good teacher for him...but Faraday became more famus scientist
i hold the opposite opinion to yours
Faraday is a far more of a giant of electromagnetism than Davy but he would not exist if Dany hadn't hired him as a chemistry assistant at the Royal Institution.
