Henry Festing Jones (1851-1928) was the friend and posthumous biographer of Samuel Butler. His biography of Butler, entitled Samuel Butler, Author of Erewhon (1835-1902) - A Memoir, (1919) won the inaugural James Tait Black Memorial Prize for biography in 1919. His other works include: Diversions in Sicily (1920), Samuel Butler: A Sketch (1921) and The Samuel Butler Collection at Saint John's College Cambridge (with A. T. Bartholomew) (1921). Augustus Theodore (Theo) Bartholomew (1882-1933) was a bibliographer and a librarian at Cambridge University for over twenty-five years. At the age of 17, he found a job as "Second-Class Assistant" at the University Library at Cambridge, earning 10 shilings a week. In 1901 he was able to enter Peterhouse, Cambridge, as an undergraduate, graduating in 1904. After graduation, the library remained the focus of his life. He began by cataloguing Lord Acton's donation to the library - a task which took nine years.
