Tor House, Carmel, California: August 5, 1940. First edition. One-page original handwritten letter on 8.5 x 11" watermarked onion skin paper, to "Miss Beittel" signed "Very sincerely/ Una Jeffers." Grace Rettew Beittel (1920-2013) wrote to over 90 artists and intellectuals while researching her college senior thesis, "Imaginary Companions in Childhood: Their Relation to Creative Ability in Adult Life," including Robinson Jeffers on June 28, 1940. Robinson drafted his response (which is in the Jeffers Archive at HRC) from which Una crafted this letter to Miss Beittel. In answer to Beittel's question, "Did you have an imaginary companion(s) when you were a child?" Una writes in part, "He was usually alone against the imaginary world, astonishing a curious or hostile people by his exploits...." And in response to "At approximately what age did you begin creative work." she responds, "He says he began to feel poetry strongly & write bad verses at fourteen." Provenance: Una's letter is included, along with Robinson's draft in COLLECTED LETTERS OF ROBINSON JEFFERS WITH SELECTED LETTERS OF UNA JEFFERS.
