Geoffrey Spencer Madan (6 February 1895 – 6 July 1947) was an English belletrist, and a collector and creator of aphorisms, many of which are recorded in his Notebooks.
There he read Classics, and he made a number of lifelong friends, including Harold Macmillan, Cyril Asquith and Ronald Knox.
Between 1920 and 1924 Madan was employed in the City of London; but in 1924 a severe attack of meningitis forced him to retire.
A private income enabled him to devote the remainder of his life to his interests, which included wine, old silver and (above all) books.
The editors (J.A.Gere and John Sparrow) provided a biographical introduction, and Harold Macmillan contributed a foreword.
