Erasmus Darwin (12 December 1731 – 18 April 1802) was an English physician who turned down George III's invitation to be a physician to the King. One of the key thinkers of the Midlands Enlightenment, he was also a natural philosopher, physiologist, abolitionist, inventor and poet. His poems included much natural history, including a statement of evolution and the relatedness of all forms of life. He was a member of the Darwin–Wedgwood family, which includes his grandsons Charles Darwin and Francis Galton. Darwin was also a founding member of the Lunar Society of Birmingham, a discussion group of pioneering industrialists and natural philosophers.

Erasmus Darwin House, his home in Lichfield, is now a museum dedicated to Erasmus Darwin and his life's work.


Early life

Born at Elston Hall, Nottinghamshire near Newark-on-Trent, England, the youngest of seven children of Robert Darwin of Elston (12 August 1682–20 November 1754), a lawyer, and his wife Elizabeth Hill (1702–1797). The name Erasmus had been used by a number of his family and derives from his ancestor Erasmus Earle, Common Sergent of England under Oliver Cromwell.[1] His siblings were:
Robert Darwin (17 October 1724–4 November 1816)
Elizabeth Darwin (15 September 1725–8 April 1800)
William Alvey Darwin (3 October 1726–7 October 1783)
Anne Darwin (12 November 1727–3 August 1813)
Susannah Darwin (10 April 1729–29 September 1789)
John Darwin, rector of Elston (28 September 1730–24 May 1805)
He was educated at Chesterfield Grammar School, then later at St John's College, Cambridge.[2] He obtained his medical education at the University of Edinburgh Medical School. Whether Darwin ever obtained the formal degree of MD is not known.
Darwin settled in 1756 as a physician at Nottingham, but met with little success and so moved the following year to Lichfield to try to establish a practice there. A few weeks after his arrival, using a novel course of treatment, he restored the health of a young man whose death seemed inevitable. This ensured his success in the new locale. Darwin was a highly successful physician for more than fifty years in the Midlands. George III invited him to be Royal Physician, but Darwin declined. In Lichfield, Darwin wrote "didactic poetry, developed his system of evolution, and invented amongst other things, an organ able to recite the Lord's Prayer, the Creed, and the Ten Commandments".[3]
Darwin was a large man who gave up weighing himself when he reached 336 pounds (24.3 stones, 153 kg). When visiting patients, he would have his driver, also a very large man, walk ahead of him to make sure the floor of a house would hold him.[4]
[edit]Marriages and children

Darwin married twice and had 14 children, including two illegitimate daughters by an employee, and, possibly, at least one further illegitimate daughter.
In 1757, he married Mary (Polly) Howard (1740–1770). They had four sons and one daughter, two of whom (a son and a daughter) died in infancy:
Charles Darwin (1758-1778)
Erasmus Darwin II (1759–1799)
Elizabeth Darwin (1763, survived 4 months)
Robert Waring Darwin (1766–1848), father of the naturalist Charles Darwin
William Alvey Darwin (1767, survived 19 days)
The first Mrs. Darwin died in 1770. A governess, Mary Parker, was hired to look after Robert. By late 1771, employer and employee had become intimately involved and together they had two illegitimate daughters:
Susanna Parker (1772–1856)
Mary Parker Jr (1774–1859)
Susanna and Mary Jr later established a boarding school for girls. In 1782, Mary Sr (the governess) married Joseph Day (1745–1811), a Birmingham merchant, and moved away.
Darwin may have fathered another child, this time with a married woman. A Lucy Swift gave birth in 1771 to a baby, also named Lucy, who was christened a daughter of her mother and William Swift, but there is reason to believe the father was really Darwin.[5] Lucy Jr. married John Hardcastle in Derby in 1792 and their daughter, Mary, married Francis Boott, the physician.
In 1775, Darwin met Elizabeth Pole, daughter of Charles Colyear, 2nd Earl of Portmore, and wife of Colonel Edward Pole (1718–1780); but as she was married, Darwin could only make his feelings known for her through poetry. When Edward Pole died, Darwin married Elizabeth and moved to her home, Radbourne Hall, four miles (6 km) west of Derby. The hall and village are these days known as Radbourne. In 1782, they moved to Full Street, Derby. They had four sons, one of whom died in infancy, and three daughters:
Edward Darwin (1782–1829)
Frances Ann Violetta Darwin (1783–1874), married Samuel Tertius Galton, was the mother of Francis Galton
Emma Georgina Elizabeth Darwin (1784–1818)
Sir Francis Sacheverel Darwin (1786–1859)
John Darwin (1787–1818)
Henry Darwin (1789–1790), died in infancy.
Harriet Darwin (1790–1825), married Admiral Thomas James Malling

Death
Darwin died suddenly on the 18 April 1802, weeks after having moved to Breadsall Priory, just north of Derby. His body is buried in All Saints Church, Breadsall.
Erasmus Darwin is commemorated on one of the Moonstones, a series of monuments in Birmingham.

Writings

Botanical works
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 names of plants 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.

Zoönomia

Darwin's most important scientific work is Zoönomia (1794–1796), contains a system of pathology, and a chapter on 'Generation'. In the latter, he anticipated some of the views of Jean-Baptiste Lamarck, which foreshadowed the modern theory of evolution. Erasmus Darwin's works were read and commented on by his grandson Charles Darwin the naturalist. Erasmus Darwin based his theories on David Hartley's psychological theory of associationism.[6] 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 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 those improvements by generation to its posterity, world without end!

Erasmus Darwin was familiar with the earlier proto-evolutionary thinking of James Burnett, Lord Monboddo, and cited him in his 1803 work Temple of Nature.

Poem on evolution

Erasmus Darwin offered the first glimpse of his theory of evolution, obliquely, in a question at the end of a long footnote to his popular poem The Loves of the Plants (1789), which was republished throughout the 1790s in several editions as The Botanic Garden. His poetic concept was to anthropomorphize the stamen (male) and pistil (female) sexual organs, as bride and groom. In this stanza on the flower Curcuma (also Flax and Turmeric) the "youths" are infertile, and he devotes the footnote to other examples of neutered organs in flowers, insect castes, and finally associates this more broadly with many popular and well-known cases of vestigial organs (male nipples, the third and fourth wings of flies, etc.)

Woo'd with long care, CURCUMA cold and shy
Meets her fond husband with averted eye:
Four beardless youths the obdurate beauty move
With soft attentions of Platonic love.
Darwin's final long poem, The Temple of Nature, was published posthumously in 1803. The poem was originally titled The Origin of Society. It is considered his best poetic work. It centres on his own conception of evolution. The poem traces the progression of life from micro-organisms to civilized society.
His poetry was admired by Wordsworth, although Coleridge was intensely critical, writing, "I absolutely nauseate Darwin's poem".[8] It often made reference to his interests in science; for example botany and steam engines.

[edit]Education of women

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.[citation needed] The school advertised on the last page is the one he set up in Ashbourne, Derbyshire for their two illegitimate children, Susanna and Mary.

Darwin regretted that a good education had not been generally available to women in Britain in his time, and drew on the ideas of Locke, Rousseau, and Genlis in organising his thoughts. Addressing the education of middle class girls, Darwin argued that amorous romance novels were inappropriate and that they should seek simplicity in dress. He contends that young women should be educated in schools, rather than privately at home, and learn appropriate subjects. These subjects include physiognomy, physical exercise, botany, chemistry, mineralogy, and experimental philosophy. They should familiarize themselves with arts and manufactures through visits to sites like Coalbrookdale, and Wedgwood's potteries; they should learn how to handle money, and study modern languages. Darwin's educational philosophy took the view that men and women should have different, but complementary capabilities, skills, spheres, and interests.[9] In the context of the times, this program may be read as a modernising influence.
[edit]Lunar Society

Other activities

In addition to the Lunar Society, Erasmus Darwin belonged to the influential Derby Philosophical Society, as did his brother-in-law Samuel Fox (see family tree below). He experimented with the use of air and gases to alleviate infections and cancers in patients. A Pneumatic Institution was established at Clifton in 1799 for clinically testing these ideas. He conducted research into the formation of clouds, on which he published in 1788. He also inspired Robert Weldon's Somerset Coal Canal caisson lock.
Darwin's experiments in galvanism were an important source of inspiration for Mary Shelley to write Frankenstein.

Cosmological speculation

Contemporary literature dates the cosmological theories of the Big Bang and Big Crunch to the 19th and 20th centuries. However Erasmus Darwin had speculated on these sorts of events in The Botanic Garden, A Poem in Two Parts: Part 1, The Economy of Vegetation, 1791:
Roll on, ye Stars! exult in youthful prime,
Mark with bright curves the printless steps of Time;
Near and more near your beamy cars approach,
And lessening orbs on lessening orbs encroach; —
Flowers of the sky! ye too to age must yield,
Frail as your silken sisters of the field!
Star after star from Heaven's high arch shall rush,
Suns sink on suns, and systems systems crush,
Headlong, extinct, to one dark center fall,
And Death and Night and Chaos mingle all!
— Till o'er the wreck, emerging from the storm,
Immortal Nature lifts her changeful form,
Mounts from her funeral pyre on wings of flame,
And soars and shines, another and the same.

Inventions

Darwin was the inventor of several devices, though he did not patent any. He believed this would damage his reputation as a doctor, and encouraged his friends to patent their own modifications of his designs.
A horizontal windmill, which he designed for Josiah Wedgwood (who would be Charles Darwin's other grandfather, see family tree below).
A carriage that would not tip over (1766).
A speaking machine (at Clifton in 1799).
A canal lift for barges.
A minute artificial bird.[citation needed]
A copying machine (1778).
A variety of weather monitoring machines.
An artesian well (1783).
[edit]Rocket engine
In notes dating to 1779, Darwin made a sketch of a simple hydrogen-oxygen rocket engine, with gas tanks connected by plumbing and pumps to an elongated combustion chamber and expansion nozzle, a concept not to be seen again until one century later.
