He mapped the electrical language of the nervous system, revealing how neurons fire with ionic currency.
Sir Alan Hodgkin, with his collaborator Andrew Huxley, cracked one of biology's fundamental codes: the mechanism of the nerve impulse. Working with the giant axon of the Atlantic squid in the late 1930s and 1940s, they performed elegant, precise experiments that seemed more akin to physics than physiology. Their work established that a nerve signal is a self-regenerating wave driven by the flow of sodium and potassium ions across the cell membrane. They didn't just describe it; they quantified it, creating a mathematical model that predicted nerve behavior with astonishing accuracy. This Hodgkin-Huxley model, for which they shared the 1963 Nobel Prize in Physiology or Medicine, became a cornerstone of neuroscience and biophysics. It provided the first complete account of how electrical activity in animals is generated, a discovery that illuminated everything from muscle contraction to brain function and paved the way for modern neurology and pharmacology.
1901–1927
Grew up during the Depression, fought World War II, and built the postwar economic boom. Defined by shared sacrifice, institutional trust, and a belief that hard work and loyalty would be rewarded.
Alan was born in 1914, placing them squarely in The Greatest Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.

Much of his pivotal research was delayed by World War II, during which he worked on radar and aviation medicine.
He conducted his famous squid axon experiments at the Marine Biological Association laboratory in Plymouth, UK.
Hodgkin was a keen birdwatcher and served as President of the Royal Society for the Protection of Birds.
He built some of his own electronic equipment for his groundbreaking experiments.
“The progress of science depends on new techniques, new discoveries and new ideas, probably in that order.”
