How did Irving Langmuir help popularize Gilbert N. Lewis's bonding theory?

Between 1919 and 1921, the American chemist Irving Langmuir played a pivotal role in popularizing and elaborating upon the chemical bonding model originally proposed by Gilbert N. Lewis in 1916.1

Langmuir’s efforts were instrumental in bringing widespread attention to the theory, which centered on the concept of the electron-pair bond. Through his work, Langmuir introduced several terms that remain fundamental to modern chemistry, most notably the term covalent and the octet rule.12

Langmuir’s active promotion of these ideas was so influential that it stimulated Lewis to return to the subject himself, leading Lewis to publish his own definitive monograph, Valence and the Structure of Atoms and Molecules, in 1923. This collaborative period of development is often referred to as the Lewis-Kossel-Langmuir theory of valence.13
