Cellular Iconoclast
A physiologist who looked inside cells, then questioned the model used to describe them. Proteins, water and ions became the cast of his lifelong scientific argument.
Cell Physiologist & Biophysicist
Born in Nanking in 1919, Ling studied biology in China before moving to the University of Chicago. He completed his doctorate under Ralph W. Gerard in 1948.
His early experiments examined membrane potential in frog muscle fibres, connecting electrical measurements with metabolism and temperature.
Ling helped refine the glass microelectrode, building on work by Judith Graham and Ralph Gerard. The technique made reliable measurements of electrical potential inside cells possible.
The 1949 paper with Gerard provides a direct route into this experimental contribution.
In A Physical Theory of the Living State, Ling set out the association–induction hypothesis. He later added a model of water ordered by its interactions with proteins.
He proposed that cellular organisation could explain properties usually attributed to membranes and ion pumps. This became a sustained challenge to the dominant account of cell physiology.
Books and papers elaborated the hypothesis across decades. Ling’s archive preserves the arguments in detail, including free texts and summaries.
His rejection of membrane-pump explanations remains outside accepted cellular physiology. Reading his claims alongside experimental work on ion-transporting enzymes makes the disagreement concrete.
