Rose is best known for having inspired the iconic play The Glass Menagerie, but her impact  pervades Williams’s works, which insistently probe society’s intolerance of difference. Whether Rose’s particular difference stemmed from neurodivergence, mental illness, a traumatic childhood in a violent home, or some combination of the above cannot be known. Disturbed by Rose’s increasing rebellion, her parents shipped the young woman off to college and later tried to find suitors for her. She eventually became emotionally unstable and was committed to a sanitarium, where she was diagnosed with schizophrenia and, in 1943, lobotomized. She spent the remainder of her life—more than five decades—institutionalized. Rose outlived her famous brother, whose will directed the bulk of his estate's earnings into a trust he had established for her.

Scholars identify Rose as one of the playwright’s most important influences: “Knowing her story expands what scholars see in his plays and what they can do with them,” Cave observes. “The more we know about Rose, the better we understand Williams’s work, and the more that work tells us about the era in which it written.” Just over a year after Rose’s lobotomy, Williams would vault into playwrighting stardom with the success of The Glass Menagerie, a “memory play” in which a poet-narrator laments leaving behind his vulnerable, physically and mentally unconventional sister, who is unable to find her place in the world. Haunted by his inability to protect Rose, Williams immortalized her tragedy in his art repeatedly throughout his career, including in the famous ending of A Streetcar Named Desire, in which the fragile, poetic Blanche DuBois is committed to an insane asylum.

The newly acquired letters do for Rose what Williams’s plays do for their characters: They center and bring to life a vibrant person who was more than her mental and emotional struggles. Rose comes across as chatty, bright, and observant, with an eye for evocative details: She recounts having dreamt about chicken salad, despairs of ever being able to dance the Charleston, and reports reading her teenaged brother’s letters out loud to friends, who thought them “quite the stuff.” Like her brother, Rose adorns her letters with doodles and sketches in the margins. Her documentation of dances she attends, of the treatment of “colored” domestic workers she encounters, and of her school reading add to what historians know about the world Williams grew up in—and about corners of it he did not see.

This acquisition, which underscores the Collection’s status as a hub for research on the playwright, will hold special appeal for participants in the annual Tennessee Williams Scholars Conference—organized and hosted by HNOC—and contributors to the Tennessee Williams Annual Review. The letters illuminate the larger context of mid-20th-century treatment of disability, and mental disability in particular. Williams’s perennially popular stage and film representations of people with mental illness and other forms of difference continue to demand that viewers pay attention to and value the lives and struggles of society’s most vulnerable outsiders. Together, Rose’s correspondence and Williams’s work can help researchers track the complicated, connected histories of disability, sexuality, race, and marginalized populations of all kinds.
