EDITH WHARTON'S LETTERS TO ANNA CATHERINE BAHLMANN: A HIGHLY IMPORTANT LITERARY CORRESPONDENCE, ENTIRELY UNPUBLISHED.
In about 1872, Edith's parents, on the suggestion of their Newport neighbors, the Lewis Rutherfurds, hired Anna Catherine Bahlmann (1849-1916), a young women of German ancestry, as tutor and later governess to the precocious 12-year-old Edith Newbold Jones, a voracious reader with strong literary inclinations. Their friendship became a close, enduring one. Years later, Edith Wharton spoke of Anna Bahlmann as "my beloved German teacher, who saw which way my fancy turned, and fed it with all the wealth of German literature, from the Minnesingers to Heine" (A Backward Glance, Lib. of America edn., p.820). In the following decades, Anna Catherine became Edith's confidant, critical reader and literary assistant. Bahlmann's influence on Wharton has remained unknown, but is richly documented in their extensive and entirely unpublished correspondence, which spans 1874 to Bahlmann's death in 1916. Its discovery permits significant new insights into the life and and literary work of Wharton.
The introduction to the Letters, ed. R.W.B. and Nancy Lewis, refers to "the oldest surviving" Wharton letter, dated 23 September 1874. The earliest letter in the Bahlmann archive (31 May 1874), pre-dates it by four months. "Almost twenty years must pass," the Lewises write, "before another letter by Edith Wharton comes into view." Remarkably, over forty of Wharton's letters in the Bahlmann archive are dated before 1894, thus filling in a major gap in Wharton's extant correspondence.
The early letters are filled with enthusiasm for her reading, which includes Daniel Deronda, Middlemarch, Shakespeare's Julius Caesar, Longfellow's "Masque of Pandora," Edward Bulwer (whose work she disliked), the Eddas, Marlowe's Faustus, the Niebelungen, Milton, Shelley and Lowell's blank verse. "You are my supreme critic in these matters," she tells Bahlmann (10/17ca.1879). She notes when her own work is published, like an early sonnet, "St. Martin's Summer," for Scribner's; four poems for Atlantic (10/16/79), her popular "The Fulness of Life" (8/18/1891), a story "That Good May Come" (11/15/93) recalling "the hours we spent in writing it out together"; remarks that the The House of Mirth is having "unprecedented success" in the Revue de Paris (12/18/1907), and in a letter of 8/16/1913 asks Bahlmannn to suggest revisions of Custom of the Country.
