The diary is that of a man who acknowledges that he is not a "Somebody" - Charles Pooter of 'The Laurels', Brickfield Terrace, Holloway, a clerk in the city of London - and it chronicles in hilarious detail the everyday life of the lower middle class during the Great Victorian age.
"The Diary of a Nobody" is so unassuming a work that even its author, George Grossmith, seemed unaware that he had produced a masterpiece. For more than a century this wonderfully comic portrayal of suburban life and values has remained in print, a source of delight to generations of readers, and a major literary influence, much imitated but never equalled.
If you don't recognise yourself at some point in "The Diary" you are probably less than human. If you can read it without laughing aloud you have no sense of humour.
