Context paragraphs:
The Story of a Great Schoolmaster: The Story of a Great Schoolmaster is a 1924 biography of Frederick William Sanderson (1857-1922) by H. G. Wells.  It is the only biography Wells wrote.  Sanderson was a personal friend, having met Wells in 1914 when his sons George Philip ('Gip'), born in 1901, and Frank Richard, born in 1903, became pupils at Oundle School, of which Sanderson was headmaster from 1892 to 1922.  After Sanderson died while giving a lecture at University College London at which he was introduced by Wells, the famous author agreed to help produce a biography to raise money for the school.  But in December 1922, after disagreements emerged with Sanderson's widow about his approach to the subject, Wells withdrew from the official biography (published in 1923 as "Sanderson of Oundle"; Wells wrote much of the text but the volume was published without listing an author) and published his own work separately.
