Mary-'Vesta Marston-Scott (1924-2024).

Memorializes Mary-'Vesta Marston-Scott (1924-2024). Comparative psychology was recognized as a defined field in psychology as early as the 1770s. Female comparative psychologists started to appear only in the first half of the 20th century. Mary-'Vesta Marston-Scott was one of the first. Born Mary-'Vesta Marston on April 5, 1924, in Jonesboro (Maine), she received her high school diploma from Calais Academy in 1941. In 1943, Mary-'Vesta enrolled at the Faculty of Psychology of the University of Maine in Orono, where she won the Charles Alexius Dickinson Sigma Mu Sigma Award (as best student in psychology) and the Anne E. Stodder Scholarship. In 1946, she obtained her Bachelor of Arts degree. In the same year, Mary-'Vesta began carrying out research in comparative psychology at the Jackson Laboratory in Bar Harbor (Maine), where she entered the Division of Behavior Studies and started working with the comparative psychologist John Paul Scott (1909-2000), for whom she became a research assistant. At the Jackson Laboratory, Mary-'Vesta adopted an ethological approach to study the social behavior of dogs and mice, presenting her earliest results (on canine psychology) in 1947 at the 16th Annual Meeting of the Genetics Society of America in Chicago and contributing to eight comparative psychology publications by 1953. After the devastating Bar Harbor Fire, which extensively damaged also the Jackson Laboratory, Mary-'Vesta decided to become a nurse, achieving her aim in 1951, when she completed a Master of Nursing degree at Yale University, followed by a Master of Public Health from Harvard University in 1957. Even though her main career had switched to nursing in the second part of her professional life, Mary-'Vesta always maintained a strong interest in psychology. In the 1960s, at Boston University, she obtained a master of arts in psychology and a doctoral degree in social psychology, receiving the title of PhD in 1968. In the 1970s, applying psychology to nursing, she investigated patient compliance with health treatments. In 1989, Mary-'Vesta edited John Paul Scott's influential book , which explored the formation of social structures in human and nonhuman animals, examining the biological underpinnings of social behavior through a comparative and evolutionary approach. On April 5, 2024, Mary-'Vesta celebrated her 100th birthday. On July 16, 2024, after a long and successful life, she passed away, serenely at her house in Orono in her native Maine.
