Sir Alan Lloyd Hodgkin was an English biophysicist and a physiologist who received the Nobel prize in Physiology or Medicine along with Sir John Eccles and Andrew Fielding Huxley for discovering the chemical processes which controlled the transmission of electrical impulses from one nerve cell in the brain to another though nerve fibers. He and his fellow scientists introduced microelectrodes into the giant nerve fibers of a squid and showed that the electrical potential of a nerve fiber transmitting an impulse is higher than a nerve fiber which remains at rest. This discovery was in contradiction to the earlier hypothesis that nerve membranes break down when an impulse was transmitted. This theory formulated by Hodgkin and Huxley is known as the ‘voltage clamp’. They found that a large amount of potassium ions is concentrated inside a nerve fiber while the solution which surrounds the fibers has a large concentration of sodium ions. They proved with the help of experiments that nerve fibers allow only potassium ions to pass through the membrane when they are at rest while only sodium ions are allowed passage when the fibers are excited. The continuous sequence of depolarization that occurs to the nerve cell membranes discovered by him is known as the ‘Hodgkin Cycle’.

Career
  • Alan Lloyd Hodgkin started his experiments on the nervous system of frogs in 1935 while he was at the University of Cambridge.
  • He received an invitation from Gasser to work at his laboratory located in the Rockfeller Institute in New York in 1937.
  • From 1937 to 1938 he learnt to dissect squid axons with the help of K. S. Cole at ‘Woods Hole’.
  • He returned to Cambridge in 1938 and started to work with one of his students, A.F. Huxley.
  • He worked for the ‘British Air Ministry’ from 1939 to 1940 on aviation medicine with Matthews at Farnborough.
  • From 1940 to 1945 he carried out various experiments on improving the radar which helped the war effort a great deal. He worked on 10 cm display and scanning systems for improving the night-fighting capabilities of aircrafts. He also worked in designing the ‘Village Inn AGLT Airborne Gun-laying system’.
  • In early 1941 he was involved in the in-flight testing of the centimetric radar system aboard one of the Bristol Blenhein aircrafts.
  • He joined the faculty at the ‘Cambridge University’ in 1945 as a teacher in the Physiology Laboratory.
  • When Huxley returned to Cambridge a few months later he teamed up with Huxley again to continue with their earlier experiments.

  • Hodgkin and Huxley carried out most of their experiments on the chemical and electrical characteristics of nerve fibers in the laboratory of the ‘Marine Biological Association’ till 1952.
  • In 1951 Hodgkin became a ‘Foulerton Research Professor’ at the ‘Royal Society’.
  • Though the war had interrupted their experiments for a certain period after 1939, Hodgkin and Huxley were able to continue with their experiments after the war had ended and in 1952 were able to publish a paper describing the findings they obtained from experimenting on nerve fibers.
  • Hodgkin served on the ‘Royal Society Council’ from 1958 to 1960 and then on the ‘Medical Research Council’ from 1959 to 1963.
  • He was made the foreign secretary of ‘Physiological Society’ from 1961 to 1967.
  • He became the President of the ‘Marine Biological Association’ in 1966 and the President of the ‘Royal Society’ in December 1970.
  • He served as a professor of biophysics at the ‘Cambridge University’ in 1970 after becoming a ‘John Humphrey Plummer Professor of Biophysics’.
  • He became the chancellor of the ‘Leicester University’ in 1971 and held the post till 1984.
  • He was appointed as the Master of the Trinity College in 1978 and served there till 1985.
