. Still intrigued with the world of psychology, Loevinger went on to enroll in graduate school at the University of California, Berkeley, where she was a research assistant for Erik Erikson. In 1943, Loevinger married Samuel Isaac Weissman (June 25, 1912 – June 12, 2007), a scientist who contributed to the

. They had a son and a daughter. Samuel Weissman worked on the weapon design of the atomic bomb in New Mexico, while Loevinger stayed at Berkeley to finish her dissertation. The family then moved to St. Louis where Jane taught part-time at the Washington University in St. Louis. After growing frustrated with her time teaching and facing the societal pressures of being a working mother, Loevinger decided to begin her own research, specifically about women and mothers. During this time, Loevinger and her research team developed a number of studies and findings, including the renowned Washington University Sentence Completion Test.
