Erasmus Darwin House, his home in Lichfield, is now a museum dedicated to Erasmus Darwin and his life's work. A school in nearby Chasetown recently converted to Academy status and is now known as Erasmus Darwin Academy.
He went to the University of Cambridge, and then studied to be a doctor in Edinburgh. He became a doctor in 1756, and worked in Lichfield in Staffordshire. He worked hard and learned a lot about medicine. Soon, lots of people respected him, and the King, George III asked him to become the Royal Doctor, but Erasmus preferred to stay where he was.
Personal life
Darwin married twice and had 14 children, including two illegitimate daughters by an employee, and, possibly, at least one further illegitimate daughter. In addition to the five children of his first marriage to Mary Howard (1740–1770), and seven to his second wife, Elizabeth Pole, there are two daughters by the governess Mary Parker, and another probable with a married woman, Lucy Smith.
His writings
Botany
Darwin formed the Lichfield Botanical Society in order to translate the works of the Swedish botanist Carolus Linnaeus from Latin into English. This took seven years. The result was two publications: A System of Vegetables between 1783 and 1785, and The Families of Plants in 1787. In these volumes, Darwin coined many of the English plant names that we use today.
Darwin then wrote The Loves of the Plants, a long poem, which was a popular rendering of Linnaeus works. Darwin also wrote Economy of Vegetation, and together the two were published as The Botanic Garden.
His last long poem, the Temple of Nature, was published after his death, in 1803. This is considered his best poetic work. It centers on his own newly conceived theory of evolution, tracing traces the progression of life from microorganisms to civilized society.
Zoology
Darwin's most important scientific work is Zoönomia (1794–1796), which contains a system of pathology, and a treatise on generation, in which he anticipated some of Lamarck's ideas on evolution.
The essence of his views is contained in the following passage, which he follows up with the conclusion that one and the same kind of living filament is and has been the cause of all organic life:
Would it be too bold to imagine that, in the great length of time since the earth began to exist, perhaps millions of ages before the commencement of the history of mankind, would it be too bold to imagine that all warm-blooded animals have arisen from one living filament, which the great First Cause endued (invested) with animality, with the power of acquiring new parts, attended with new propensities, directed by irritations, sensations, volitions and associations, and thus possessing the faculty of continuing to improve by its own inherent activity, and of delivering down these improvements by generation to its posterity, world without end!
This is a clear statement of the kind of evolutionary thinking which Lamarck is known for.
Later works
Darwin's idea of evolution surfaced in several of his other works. In the Loves of the Plants (1789), reprinted in several editions as The Botanic Garden, there occurs the comment: "Perhaps all the productions of nature are in their progress to greater perfection!". All these natural history works are in the form of poems, and so they are not satisfactory from the point of view of modern science. But the 18th century was a time when intelligent men made connections; the specialist types of scientist occurred first in the lifetime of his grandson Charles.
The last two leaves of Darwin's A plan for the conduct of female education in boarding schools (1797) contain a book list, an apology for the work, and an advert for "Miss Parkers School". The work probably resulted from his liaison with Mary Parker. The school advertised on the last page is the one he set up in Ashbourne, Derbyshire for their two illegitimate children, Susanna and Mary.
