It's Aurelia Plath's 115th birthday (born April 26, 1906). Happy birthday, Sylvia's mom, and here is a present for you.
Hoping to write Sylvia Plath's biography, researcher Harriet Rosenstein on June 16, 1970, interviewed Sylvia's psychiatrist Dr. Ruth Barnhouse Beuscher, who treated Sylvia at McLean Hospital in 1953 and later. Among the first topics Rosenstein and Beuscher discussed was The Bell Jar as autobiography. Rosenstein took extensive notes, now in the Rosenstein Papers at Emory University. (How do I know what's in those papers? I went there in March 2020.)
Beuscher told Rosenstein The Bell Jar is factual, that what happened to its narrator Esther Greenwood happened to Sylvia, but some events were moved or altered. Fourth on the list:
"Esther's easy admission that she hated her mother [is] inaccurate. She [Sylvia] had spent at least the first month in the hospital asserting that she loved her mother. Beuscher says that she had to work hate admission out of Sylvia."
Aurelia, when Rosenstein interviewed you a few weeks later, in July, you blamed psychiatry for making Sylvia hate you. For the rest of your life you kept saying and writing that. Now we have Beuscher's word for what happened.
Beuscher by 1970 had become a Christian theologian like her father but was also deeply interested in the occult. She pursued a personal friendship with Rosenstein and entrusted to her the desperate letters Sylvia wrote to Beuscher in 1962 and 1963.
