Willard Stanton Small (1870-1943): The man who made the maze

Willard Stanton Small (1870-1943) was among the earliest scientists to perform psychological research with rats and conducted the first experiment with a rat in a maze. This article represents the first biography devoted to Small and provides highlights from his childhood, undergraduate and graduate work, personal life, and professional career. Special attention is given to the events that led to the first rat maze experiment, which Small performed as a graduate student at Clark University. A detailed analysis of Small's published report of the maze experiment is also provided. His employment history after graduate school is discussed and includes teaching and administrative roles at multiple academic institutions, in addition to his role as a field investigator for the U.S. Bureau of Education. It is shown that Small's work impacted not only comparative psychology, but also U.S. public health, school hygiene, and education. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
