Charles Galton Darwin - Private Life

Private Life

In 1925 he married Katharine Pember, a mathematician. They had four sons and a daughter:

• Cecily Darwin (born 1926) became an X-ray crystallographer and in 1951 married John Littleton of Philadelphia.
• George Pember Darwin (1928–2001) worked developing computers, and then (1964) married Angela Huxley, daughter of David Bruce Huxley. She was also a granddaughter of the writer Leonard Huxley and a great-granddaughter of Thomas Huxley, "Darwin's Bulldog".
• Henry Galton Darwin (1929–1992) was with the British Foreign Office, and married Jane Christie.
• Francis William Darwin (1932–2001) was a zoologist and taught at the University of London, and married in 1974.
• Edward Leonard Darwin (born 1934) became a civil engineer.

In his spare time, Darwin also served as a wartime vice-president of the Simplified Spelling Society.

On his retirement, his attention turned to issues of population, genetics and eugenics. His conclusions were pessimistic and entailed a resigned belief in an inevitable Malthusian catastrophe, as described in his 1952 book The Next Million Years. He first argued in this book that voluntary birth control (family planning) establishes a selective system that ensures its own failure. The cause is that people with the strongest instinct for wanting children will have the largest families and they will hand on the instinct to their children, while those with weaker instincts will have smaller families and will hand on that instinct to their children. In the long run society will consist mainly of people with the strongest instinct to reproduce. This would ultimately have dysgeneic effects.

In later years he travelled widely, an enthusiastic collaborator across national borders and an able communicator of scientific ideas. He died in Cambridge.
