Richard Owen, F.R.S. (1804–92) was a controversial and influential palaeontologist and anatomist. Originally from Lancaster, he studied medicine at the University of Edinburgh and at London's St Bartholomew's Hospital. He grew interested in anatomical research and, after qualifying as a surgeon, became assistant conservator in the museum of the Royal College of Surgeons, and then superintendent of natural history in the British Museum. He became an authority on comparative anatomy and palaeontology, coining the term 'dinosaur' and founding the Natural History Museum. He was also a fierce critic of Darwin's theory of evolution by natural selection, and engaged in a long and bitter argument with Thomas Huxley, known as 'Darwin's bulldog' for his belligerent support of the theory. Published in 1894, this two-volume biography of Owen was written by his grandson and draws on Owen's diaries and a wealth of correspondence.
