William Carpenter (1813 85) was trained as a doctor; he was apprenticed to an eye surgeon, and later attended University College London and the University of Edinburgh, obtaining his M. D. in 1839. Rather than practising medicine, he became a teacher, specialising in neurology, and it was his work as a zoologist on marine invertebrates that brought him wide scientific recognition. His Principles of Mental Physiology, published in 1874, developed the ideas he had first expounded in the 1850s, and expounds the arguments for and against the two models of psychology then current automatism, which...

William Bateson claimed at the Darwin Centenary in 1909 that Samuel Butler (1835 1902) was 'the most brilliant and by far the most interesting of Darwin's opponents, whose works are at length emerging from oblivion.' Best remembered today as the author of the novels Erewhon and The Way of All Flesh, he also wrote on a range of subjects from translations of Homer to studies of evolutionary thought. In his Life and Habit (published in 1878) Butler contended that much of inheritance was based on habit making a feature ingrained, to the extent that it could pass between generations. However, he...

The geological writings of Hugh Miller (1802 56) did much to publicise this relatively new science. After an early career in banking in Scotland, Miller became editor of a newly founded Edinburgh newspaper, The Witness, in which he published a series of his own articles based on his geological research, a collection of which was issued as a book, The Old Red Sandstone, in 1841, and led to the Devonian geological period becoming known as the 'Age of the Fishes'. Footprints of the Creator (1849) described his reconstruction of the extinct fish he had discovered in the Old Red Sandstone and...

Astronomer and philosopher Sir John Herschel (1792 1871), the son of William and the nephew of Caroline, published his 1833 Treatise on Astronomy in the 'Cabinet Cyclopaedia' series of which the first volume had been his enormously successful Preliminary Discourse on the Study of Natural Philosophy. He is regarded as the founder of the philosophy of science, and made contributions in many fields including mathematics, the newly discovered process of photography, and the botany of southern Africa, which he studied while making astronomical observations of the southern hemisphere, and where he...

William Bateson (1861 1926) began his academic career working on variation in animals in the light of evolutionary theory. He was inspired by the rediscovery in 1900 of the 1860s work on plant hybridisation by the Austrian monk Gregor Mendel (included here as an appendix) to pursue further experimental work in what he named 'genetics'. He realised that Mendel's results could help to solve difficult biological questions and controversies and to challenge the status quo in evolutionary studies. Annoyed by the 'apathetic' stance of his evolutionist colleagues, and incensed by a scathing critique...

William Bateson (1861 1926) began his academic career working on variation in animals in the light of evolutionary theory. He was inspired by the rediscovery of Gregor Mendel's work on plant hybridisation to pursue further experimental work in what he named 'genetics'. He realised that Mendel's results could help to solve difficult biological questions and controversies which others had glossed over, and to challenge assumptions underlying evolution as it was understood at the time. After two years as Professor of Biology at Cambridge he left in 1910 to become Director of the newly founded...

A 1909 retrospective of Darwin's work and its profound impact by some of the most eminent scholars of the time.

The development of Charles Darwin's views on evolution by natural selection has fascinated biologists since the 1859 publication of his landmark text On The Origin of Species. His experiences, observations and reflections during and after his pivotal journey on the Beagle during 1831 36 were of critical importance. Darwin was not, however, a man to be rushed. While his autobiography claims that the framework of his theory was laid down by 1839, its first outline sketch did not emerge until 1842. That essay was heavily edited, with many insertions and erasures. It formed the vital kernel of...

Darwin's detailed analysis of what actually happens to a body in a state of fear, or joy, or anger.

Two studies of barnacles from 1851 and 1854 which cemented Darwin's reputation as a expert taxonomist and biologist.
