Blagden was born at Wotton-Under-Edge, Gloucestershire. He studied medicine at Edinburgh and received his M.D. in 1768. He was elected FRS in 1772 and served as a medical officer in the British Army from about 1776 to 1780. He was Henry Cavendish's assistant from 1782 to 1789, from whom he received an annuity and a considerable legacy. Blagden succeeded Paul Henry Maty as Secretary of the Royal Society in 1784 (while the Society was divided over the efficacy of its President, Sir Joseph Banks, a close friend of Blagden's), serving until 1797. Both in this capacity and as Cavendish's assistant he became involved in the prolonged 'water controversy' - who had priority in discovering the composition of water, claimed by both Cavendish and James Watt in England and A L Lavoisier in France. Blagden admitted responsibility for conveying, quite well-meaningly, word of the experiments and conclusions of both Cavendish and Watt to Lavoisier; and he overlooked errors of date in the printing of Cavendish's and Watt's papers. His experiments on the effects of dissolved substances on the freezing point of water led to what became known as 'Blagden's Law', where he concluded that salt lowers the freezing point of water in the simple inverse ratio of the proportion the water bears to it in the solution. In fact Richard Watson had first discovered the relationship in 1771. Blagden spent much of his time in Europe, particularly in France, where he had many friends among French scientists such as C L Berthollet. He died in Arcueil in 1820. He was knighted in 1792.

Purchased by the Royal Society in 1947. A further two boxes were purchased for £2,000 from the Fairhurst estate in 2000.

The correspondence, papers and diaries of Sir Charles Blagden. Blagden's papers are interesting on several levels, generally for his close contact with European men of learning, and his relationship with Sir Joseph Banks. Blagden's professional researches are represented by medical notes in the boxed sequence. These are grouped with papers on other subject interests, including linguistics, e.g. a draft Tahitian-English dictionary, compiled from conversations with Omai, whom Blagden inoculated after Omai's voyage to England with James Cook. Blagden's interest in antiquities and travel is documented by diary entries, as is his intercourse with fellow scientists, particularly those associated with the founding of the Royal Institution.
