Gilbert N. Ling (b. Dec 26 1919, Nanking, China; US citizen) is a cell physiologist, Biochemist and scientific investigator and author of five books relating to his revolutionary Association Induction Hypothesis. His most recent book published in 2014 is entitled What is Life Answered? Ling, during 50 years of research from 1946, has carried out numerous scientific experiments that attempt to disprove the view of the cell as a membrane containing a number of pumps such as the sodium potassium pump and the calcium pump and channels that engage in active transport. In 1962 he introduced the Association Induction Hypothesis (AIH), a unifying, general theory of the living cell, an alternative hypothesis to the Membrane and Membrane pump theories and three years later added the Polarized-oriented multilayer theory of cell water which contributed to the development of MRI Cancer Imaging. In 1944 he won the biology slot of the sixth Boxer Indemnity Scholarship, a nationwide competitive examination that allowed Chinese science and engineering students full scholarship to study in a United States University. In 1947 he co-developed the Gerard-Graham-Ling microelectrode, a device that allows scientists to more accurately measure the electrical potentials of living cells.
