[4] She married Otto Emil Plath in 1932 and subsequently gave birth to daughter Sylvia in the same year and son Warren in 1935.
To support her children, Mrs. Plath took a job in 1942 as an instructor of medical secretarial skills at Boston University, attaining the rank of associate professor.
Playwright Rose Leiman Goldemberg in 1979 successfully adapted Mrs. Plath's book for the stage,[7] and the play's Paris production formed the basis for the French-language movie Letters Home (1986),[8] directed by Chantal Akerman.
In 1977, Indiana University at Bloomington's Lilly Library acquired for its archives Mrs. Plath's collection of Sylvia's letters, childhood diaries and memorabilia, and early poems and stories.
Sylvia Plath made reference to her maternal grandmother by making "Esther Greenwood" the name of the heroine in her 1963 semi-autobiographical novel The Bell Jar.
