The reference to stress is ubiquitous in modern society, yet it is a relatively new field of research. The following article provides an overview of the history of stress research and its iterations over the last century. In this article, I provide an overview of the earliest stress research and theories introduced through physiology and medicine and eventually as a concept in psychology. I begin with an exploration of the research of biological stressors 1st explored by experimental physiologist Claude Bernard and eventually adopted as a foundational concept in stress research when Walter Cannon expanded on Bernard's work and identified homeostasis. The contributions of Hans Selye, considered the father of stress research; Sir William Osler; Yerkes and Dodson; and Richard Lazarus are also discussed.
