Susy Clemens

Olivia Susan Clemens (March 19, 1872 – August 18, 1896) was the second child and eldest daughter of Samuel Clemens, who wrote under the pen name Mark Twain, and his wife Olivia Langdon Clemens. She inspired some of her father's works, at 13 wrote her own biography of him, which he later published in his autobiography, and acted as a literary critic. Her father was heartbroken when she died of spinal meningitis at age 24.

Her biography of her father was published in 1988 in its entirety as ''Papa: An Intimate Biography of Mark Twain'', a volume which also included a biography of Susy Clemens and her correspondence with her father. Provided by Wikipedia
