William Erasmus Darwin

William Erasmus Darwin (27 December 1839 – 8 September 1914) was the first-born son, and the eldest of all the children of Charles and Emma Darwin, and the subject of child development studies by his father.

Life He was educated at Rugby School and Christ's College, Cambridge, and later became a banker at Grant and Maddison's Union Banking Company in Southampton. In 1877 he married an American, Sara Price Ashburner Sedgwick (1839 – 1902), daughter of Theodore Sedgwick. William was a great believer in university education being available to all, and championed the establishment of a university college in Southampton in 1902. The Darwins had no children of their own, and after his wife died, William devoted himself much to his nieces Gwen Raverat, Frances Cornford, and Margaret Keynes. William died on 8 September 1914 at Sedbergh in Cumbria. Raverat remembered him fondly as an eccentric and entirely unselfconscious man in her childhood memoirs Period Piece (1952).

There is a story about him at my grandfather's funeral at Westminster Abbey. He was sitting in the front seat as eldest son and chief mourner, and he felt a draught on his already bald head; so he put his black gloves to balance on the top of his skull, and sat like that all through the service with the eyes of the nation upon him. William is primarily notable as a subject of Charles Darwin's studies of infant psychology. Darwin was very fond of his son; at his birth he called him "a prodigy of beauty & intellect", and named him after his own grandfather Erasmus Darwin. During William's first three years his father kept a diary of gestures and facial expressions the infant made. The studies were part of Darwin's comparison between animal and human development, after he had already thoroughly studied orangutan babies at the London Zoo. The diary contains observations on the child learning to follow a candle with his eyes after nine days, smiling with his eyes after six weeks and three days, and developing distinctive cries adjusted to specific situations after eleven weeks. He also noticed the development of more profound personality traits, such as reason and, at two-and-a-half years, conscience. Charles Darwin published his findings in the journal Mind in June 1877, in an article titled "A biographical sketch of an infant". The studies were also an influence behind his work The Expression of the Emotions in Man and Animals, published in 1872. Darwin's work on infant development and child psychology inspired other academics, such as the German psychologist William Preyer and the American James Mark Baldwin, who acknowledged Darwin's influence in his 1913 History of Psychology. William was a keen amateur photographer, and took several portraits of members of his family. William Darwin and his wife are buried in St Nicolas Church, North Stoneham, Hampshire; having lived in Bassett, near Southampton, Hampshire.
