Ingold, Christopher Kelk

20th Century
Born: London (England), 1893
Died: Edgware (England), 1970
Ingold began scientific studies at the Hartley University, Southampton and entered in 1913 the Imperial College. Here he was lecturer in organic chemistry (1921). He was appointed at the Leeds University and in 1930 at the University College, London. He made contributions to the concept of resonance and mesomerism, the prediction of reactions by his schema of substitution and elimination mechanisms and several aspects of physical chemistry (measurements of dipole moments, kinetics, molecular spectroscopy). Ingold created a new discipline: physical organic chemistry. He introduced a fundamental reform of chemical theory and chemical language.
