Henry Baker (8 May 1698 – 25 November 1774) was a British naturalist.
He was born in Chancery Lane, London, 8 May 1698, the son of William Baker, a clerk in chancery. When he was 15, he was apprenticed to John Parker, a bookseller. At the close of his indentures in 1720, Baker went on a visit to John Forster, a relative, who had a deaf-mute daughter, then eight years old. As a successful therapist of deaf people, he went on to make money, by a system that he kept secret. His work as therapist caught the attention of Daniel Defoe, whose youngest daughter Sophia he married on 30 April 1729.
In 1740, he was elected fellow of the Society of Antiquaries and of the Royal Society. In 1744, he received the Copley gold medal for microscopical observations on the crystallization of saline particles.
He was one of the founders of the Society for the Encouragement of Arts, Manufactures and Commerce in 1754 (later the Society of Arts), and for some time acted as its secretary. He died in London, and was buried at St Mary le Strand.
Under the name of Henry Stonecastle, Baker was associated with Daniel Defoe in starting the Universal Spectator and Weekly Journal in 1728. Defoe in fact did little except at the launch of the publication, intended as an essay-sheet rather than a newspaper. It appeared until 1746, running to 907 issues.[1] Baker's involvement as editor continued until 1733.[2] Among the major early contributors was the journalist John Kelly.[3]
He contributed many memoirs to the Transactions of the Royal Society. Among his publications were A Short History of Speech (1723), The Microscope made Easy (1743), Employment for the Microscope (1753),[4] where he noted down the presence of dinoflagellates for the first time as "Animalcules which cause the Sparkling Light in Sea Water", and several volumes of verse, original and translated, including The Universe, a Poem intended to restrain the Pride of Man (1727).[5] [6]
His name is perpetuated by the Bakerian Lecture of the Royal Society, for the foundation of which he left by will the sum of £100.
