Abstract

The Sir Charles Blagden Papers contain scientific and travel notes, correspondence, and printed material documenting aspects of the life and scientific work of Sir Charles Blagden. These include observations on travel in England and on the continent in the 1780s; memoranda on scientific experiments and observations, including notes by Lavoisier; letters to his brother, John Blagden Hale; and proof sheets of Philosophical Transactions for 1789.

Sir Charles Blagden (1748-1820)

Sir Charles Blagden was born in Gloucestershire, England in 1748. He received his M.D. from the University of Edinburgh in 1768. He was elected a Fellow of the Royal Society in 1772, where he met and became friends with Joseph Banks. After serving as a surgeon in the British Army during the American revolution, Blagden returned to London, where by early 1783 he had become an assistant to the eccentric scientist Henry Cavendish. Blagden assisted Cavendish until 1789, and Cavendish provided him with a life annuity; he later bequeathed Blagden 15,000 pounds.

Blagden was elected one of the secretaries of the Royal Society in 1784, and remained loyal to its president Joseph Banks throughout the many controversies of the following decade. He visited continental Europe annually until the French Revolution and was elected a corresponding member of the Académie des Sciences in 1789; his friends included Antoine Lavoisier, Georges Cuvier, and Claude Louis Berthollet.

Blagden was involved in the "water controversy" that began in 1783. This was a dispute among Lavoisier, Cavendish, and James Watt over who was the first to discover that water is a compound; as Cavendish's assistant and secretary of the Royal Society, Blagden played a central role in the still-unsettled contest. The most important of Blagden's own discoveries was published in 1788. His demonstration that the freezing point of a solution decreases in direct proportion to the concentration of the solution is known as "Blagden's law."

Although Blagden courted Lavoisier's widow and Count Rumsford's daughter, among others, he remained unmarried. He died of apoplexy at the home of his friend Berthollet, near Paris, in March of 1820, and was buried in the cemetery of Père Lachaise.
