Years later, after Jobs left Apple, he acknowledged Lisa and attempted to reconcile with her. Chrisann Brennan wrote that "he apologized many times over for his behavior" to her and Lisa and "said that he never took responsibility when he should have, and that he was sorry". After reconciling with her, nine-year-old Lisa wanted to change her last name and Jobs was happy and relieved to agree to it. Jobs legally altered her birth certificate, changing her name from Lisa Brennan to Lisa Brennan-Jobs. Brennan credits the change in Jobs to the influence of Brennan-Jobs' newly found biological aunt, author Mona Simpson, who worked to repair the relationship between Brennan-Jobs and her father.
