Harry F. Harlow is best known for his studies of mother love and the importance of social interaction in primate learning. He was born in Fairview, Iowa, in 1905. He received his BA and PhD in psychology from Stanford University and immediately joined the faculty at the University of Wisconsin, where he established the Psychology Primate Laboratory. It expanded and merged with the Wisconsin Regional Primate Laboratory in 1964, with Harlow as its director. The Wisconsin Primate Centre drew in several leading scientists, including humanistic psychologist Abraham Maslow (Harlow, 2009, 98).
