Samuel L. Clemens oldest daughter.
Susy wrote a biography of her father in 1885 when she was 13. She described her impressions of her father and her happy family life. She may have been frustrated by society's refusal to see her as anything other than the daughter of Mark Twain. She also disapproved of society referring to her father as a humorous writer rather than a serious writer.
Susy died at the age of 23 from spinal meningitis.
