Question: What pseudonym did the author for this novel to which her poem "Mad Girl's Love Song" is included as a note?

<P0-S0> Roy Croft is a poet frequently given credit for writing a poem titled "Love" and beginning "I love you not only for what you are, but for what I am when I am with you." <P0-S1> . <P0-S2>  The poem, which is commonly used in wedding speeches and readings is quoted frequently. <P0-S3>  It was included in a 1936 anthology entitled "Best Loved Poems of American People", edited by a Hazel Felleman, and published by Doubleday (ISBN  ) and appears without further attribution in "The Family Book of Best Loved Poems", edited by David L. George and published in 1952 by Doubleday & Company, Inc., then of Garden City, New York. <P0-S4>  German translations of the poem circulate with the title "Ich liebe Dich" ("I Love You") but are (wrongly) credited to the Austrian poet Erich Fried. <P0-S5>  The translation(s) led to the speculation that the poem was just a translation of Erich Fried's work and Roy Croft was a pseudonym used by a translator who wanted to keep all royalties from publication (rather than sharing them with Fried's estate) or who simply did not want to go through the trouble of obtaining a license from a foreign entity. <P0-S6>  Taking into account that the poem was already published in 1936 (where Erich Fried was only 15) it seems very unlikely that Erich Fried could be the author. <SEP> <P1-S0> "Eastern poem on the death of Pushkin" is an elegy of Azerbaijani author Mirza Fatali Akhundov, composed in 1837 in Persian. <P1-S1>  This poem was his first published work. <P1-S2>  In 1837 Akhundov prepared a Russian prose translation of his poem, and his friend Bestuzhev a versified one. <P1-S3>  First time the poem was published in the journal "Moskovskiy Telegraph" (Akhundov's translation). <P1-S4>  The poem was also published in the journal "Moskovskiĭ Nablyudatel", with an editorial note welcoming the poem as a tribute not merely to Pushkin but to Russian culture as a whole. <P1-S5>  Translation of Bestuzhev was published in 1874 in journal "Russkaya Starina". <P1-S6>  Original version of the poem was found and published only in 1936 (translator Pavel Antokolsky). <SEP> <P2-S0> The Bell Jar is the only novel written by the American writer and poet Sylvia Plath. <P2-S1>  Originally published under the pseudonym "Victoria Lucas" in 1963, the novel is semi-autobiographical, with the names of places and people changed. <P2-S2>  The book is often regarded as a "roman à clef" since the protagonist's descent into mental illness parallels Plath's own experiences with what may have been clinical depression. <P2-S3>  Plath died by suicide a month after its first UK publication. <P2-S4>  The novel was published under Plath's name for the first time in 1967 and was not published in the United States until 1971, in accordance with the wishes of both Plath's husband, Ted Hughes, and her mother. <P2-S5>  The novel has been translated into nearly a dozen languages. <P2-S6>  The novel, though dark, is often read in high school English classes. <SEP> <P3-S0> "Mad Girl's Love Song" is a poem written by Sylvia Plath in 1951, while she was a student at Smith College. <P3-S1>  It is written in the villanelle poetic form and is generally included in the biographical note appended to Plath's novel, "The Bell Jar".
