About
Peter Prenzel-Guthrie (1926–2013) was a Professor of Psychology at Carleton College from 1960 to 1992. He specialized in developmental psychology, behaviorism, and the history of mental health treatment, particularly focusing on individuals with developmental delays. Known for his dedication to students and colleagues, he served as department chair and was celebrated for his mentorship and warm personality.
His research interests included the application of behavioral principles to human behavior modification, evidenced by anecdotes about his use of self-punishment techniques for smoking cessation. He actively engaged with students through independent studies (e.g., advising Scott Mattson on sexuality and gender studies) and maintained a deep connection to the Psychology Department even after retirement.
Peter was renowned for his storytelling, sharing humorous tales of Carleton's early psychology experiments (e.g., pigeon-capturing in the chapel bell tower) and student pranks. Colleagues admired his commitment to the liberal arts ethos, his support for faculty, and his ability to inspire curiosity in both psychology and Minnesota's cultural landscapes.
A memorial service was held at Carleton Chapel in January 2014, reflecting his enduring legacy as a beloved educator, mentor, and community member.
