Richard Darwin Keynes Dies

Richard Darwin Keynes, a great-grandson of Charles Darwin and a nephew of John Maynard Keynes, died in June. He was 90. An obituary in the UK's Guardian notes that Keynes "rose to eminence in his own right in the field of physiology." He studied the electrical conduction of signals along nerves, showing that the impulse was associated with the movement of sodium ions and potassium ions, and determined how electrical eels are electric. Keynes also wrote a number of books about Darwin. "[He] made a significant contribution to our understanding and appreciation of Darwin's genius," writes Julian Fitter in the Guardian.
