La Peau de chagrin
Balzac used the character Foedora in three other stories, but eventually wrote her out of them after deciding on other models for social femininity. In later editions of "La Peau de chagrin", he changed the text to name one of the bankers "Taillefer", whom he had introduced in "L'Auberge rouge" (1831). He also used the name Horace Bianchon for one of the doctors, thus connecting the book to the famous physician who appears in thirty-one stories in "La Comédie humaine". So vividly had the doctor been rendered that Balzac himself called out for Bianchon while lying on his deathbed.
