During the 1950s, she became involved with the Tufts University establishment of what became known as the Eliot-Pearson School. She continued teaching at various institutions including Pacific Oaks College in Pasadena, California. Her former Radcliffe classmate, Anna E. Holman, also a teacher as well as a poet, was her lifelong partner. The couple lived together in Concord until Anna’s death in 1969. Abigail died at age 100 after a life of service to the education of young children, a field that she helped establish.
