The book Education towards spiritual resistance: The Jewish Landschulheim Herrlingen, 1933 to 1939 by Lucie Schachne documents this remarkable school, which was closed in 1939.

Walter was sent to a school in the hamlet of Wykey in Shropshire, which was in a large country house where they bred cocker spaniels.

Since it was difficult to find a replacement during the war period, Walter was asked to teach math, in part because she had earned a mark of distinction on her Cambridge University School Certificate exam.

The main purpose of the Institute, sponsored by the National Bureau of Standards and funded by the Office of Naval Research, was to work towards the further development of high-speed automatic digital computing machinery.

The senior staff at the Institute included D.H. Lehmer (director), Mark Kac, Irving Kaplansky, and A Adrian Albert.

[9] She stepped down as department chair after four years, remaining there teaching until 1965 when she left to concentrate on her doctorate at Harvard Graduate School of Education.

She retained close relationships with her students from Simmons over the years; several of the first math majors stayed in touch with her until her death.

In 1960, during her tenure at Simmons, Walter received a fellowship to attend the National Science Foundation Summer Program at Stanford University in Palo Alto, California.

[11] Also during her years at Simmons, Walter began working on her doctoral degree at the Harvard Graduate School of Education (HGSE) in Cambridge, Massachusetts.

In 1967, Dr. Walter formed a group called the Boston Area Math Specialist (BAMS) which gives monthly workshops for practicing teachers.

Dr. Walter was actively involved in a group that was formed in Cambridge, Massachusetts called The Philopmorphs, which met at the Carpenter Center for the Visual Arts.

Walter published over 40 journal articles and gave nearly 100 workshops and talks in the United States, Canada, England, Denmark, Hungary, and Israel.

[2] In 2003, Marion Walter was nominated by BAMS and subsequently elected to the Massachusetts Hall of Fame for Mathematics Educators.

[10] In 2015, the University of Oregon Department of Mathematics created the Marion Walter Future Teachers Award, which is given annually to a graduating math major with a secondary education focus.
