Dr. Stanley wrote more than 200 papers. She was president of the International Academy for Suicide Research and served on boards and committees of many professional organizations. She also continued her clinical practice, treating patients who struggled with suicidal feelings.
Ms. Morris, Dr. Stanley’s daughter, said that her mother was modest about her professional success but was always thrilled to hear from clinicians in far-flung places who had used the techniques she developed to help patients.
“She was deeply touched by that, no doubt,” she said in an interview. “She found it very, very, very meaningful and very passionate. The work was so fulfilling to her, both on a personal level and on a larger level, to have been of service.”
