Sir Humphrey Davy was fired at the pharmacy where he worked because
he caused too many explosions. In 1799 one of his experiments
showed that two cold substances can melt when they are rubbed
to each other without any additional heat. Also in 1799 he was
able to isolate nitrous oxide (or laughing gas) and tried it
on himself. He inhaled it for seven minutes and was completely
intoxicated. He realised it left no damage to people who used
it and realized that it might be used as an anesthetic during
operations. But he left it at that and it would be 45 years
later before dentists would start using it as an anesthetic.|
In 1801 the Royal Institution in London appointed him as a lecturer and the yong Michael Faraday attended his lectures. An intoxication lamed him and another explosion temporary took away his eyesight in 1811. He hired Faraday to assist him and a long collaboration and friendship followed. Davy was knighted in 1812 and three days later he married a rich and very beautiful Scottish widow, Jane Apreece (1780-1855).
Together with his wife and Michael Faraday he travelled through Europe from 1813 until 1815. When he returned to England he invented a miner's safety helmet with a lamp that continued to give light under difficult air circumstances. He didn't patent this invention and later it was falsely accused of plagiarism by engineer George Stephenson, who had designed a different lamp independently. His marriage wasn't too happy, but in 1818 he travelled once more to the continent with Jane. They visited Lord Byron in Ravenna as well as Venice. Davy and Byron knew each other from England and Davy was among the few people from England that Byron wanted to see.
The relation between Davy and Faraday cooled after Davy criticized Faraday and the latter ceased his research in electromagnetism until Davy's death.
In 1827 Davy had a series of strokes and it became clear that he suffered from a heart disease that could kill him at any moment. He travelled restlessly on the continent without his wife, frequently visiting an inn in Laibach where he was nursed by a the daughter of the owner, Josephine Dettela. During this time he wrote the mysterious and influential "Consolation in travel, or, The Last Days of a Philosopher".
In 1829 he moved to Rome and when it became clear he would die soon his wife and his brother John hurried to Rome. His condition worsened, but he indicated that he wanted to travel once more and they moved to Geneva, where he died.
