Michael Faraday (1791-1867), British chemist and physicist, holding a heavy glass bar which he used to show the action of magnetism on light. Despite lacking a formal education, Faraday made several major advances in the fields of chemistry, magnetism and electricity. He devised the first electric motor and equipment such as transformers and dynamos. He worked at the Royal Institution, London, where his lectures helped popularise science among the general public. Photographed in the 1850s by Maull and Polyblank as part of their 'Living Celebrities' series. The Faraday volume was published in October 1857.
