Fictional character
Nigel Molesworth is a fictional character, the supposed author of a series of books about life in an English prep school named St Custard's. The books were written by Geoffrey Willans, with cartoon illustrations by Ronald Searle.
The Molesworth books were the result of an approach by Willans to the cartoonist, Searle, to illustrate a series of books based on a column he had been writing for "Punch". They appeared in instalments in the children's magazine "The Young Elizabethan", described by Molesworth as "the super smashing New Young Elizabethan ahem (advert.)". Searle had grown disillusioned with his highly popular "St Trinian's School" series but had promised his publisher Max Parrish another Christmas best-seller. While Searle was initially sceptical about another school-based project, he was won over by the examples he was given to read by Willans. Between the initial publication in 1953 and Willans' death in 1958 at the age of 47 three books were completed and most of a fourth ("Back in the Jug Agane") written; the "Compleet Molesworth" anthology was also under way. The first book, Down with Skool!, was published in October 1953 and by that Christmas had sold, according to Searle, 53,848 copies, surpassing the performance of the previous year's "The Terror of St Trinian's".
St Custard's.
Nigel Molesworth is a schoolboy at St Custard's, a fictional (and dysfunctional) prep school located in a carefully unspecified part of England. It is ruled with an iron fist by Headmaster "GRIMES" (BA, Stoke-on-Trent), who is constantly in search of cash to supplement his income and has a part-time business running a whelk stall. Other masters include Sigismund Arbuthnot, the "mad maths master", who frequently appears as Molesworth's nemesis in his daydreams.
St Custard's, according to Molesworth, "was built by a madman in 1836". The school's traditional local rivals are Porridge Court, who regularly beat St Custard's convincingly in all sporting events.
Molesworth's spelling is consistently poor throughout all the books, as many words are rendered phonetically, including the names of those Molesworth knows. Grimes' name is one of the very few he spells correctly, but he always writes it in all capital letters to signify his fear of him. Regardless, many fans find this feature endearing. The phrase "as any fule kno", appended to many of Nigel's pronouncements, has achieved fame beyond its author and can sometimes be seen in the mainstream British press (usually in a satirical context; the phrase often appears in "Private Eye"). It was used by J. K. Rowling to end an essay she wrote for "Pegasus", the journal of the University of Exeter Department of Classics and Ancient History, reminiscing on her studies there. In fact, Rowling mentions in the essay that she had read the books. (Notably, there is mention of a 'Latin pla' which Molesworth has to read: 'the Hogwarts'. The name also crops up for the headmaster of Porridge Court, who is named 'Hoggwart' in the book.) 
The phrase 'as any fule kno' was also used as the title of a Deep Purple song, "Any Fule Kno That".
The books in the series are, in order of original publication:
They are part of a British tradition of children's books set at boarding schools (school stories), which includes the Billy Bunter stories, the Jennings novels and most recently the Harry Potter books. Unlike these others, however, the Molesworth books do not consist of linear storylines but rather feature Molesworth's wisdom on a variety of topics as well as his fanciful daydreams. The topics covered extend from boarding-school life to reflections on the culture of 1950s Britain. Television (then still relatively novel to British households), the start of space travel and the atomic age, the Davy Crockett craze and "How to be a young Elizabethan" all feature, as well as more timeless topics such as Christmas, the French, journalism (with "N. Molesworth, Ace Reporter") and "Gurls".
Simon Brett later wrote two sequels to the series in which a grown-up Nigel offered his observations on subjects such as jobs, family, holidays and D.I.Y.
The Lost Diaries of Nigel Molesworth.
In 2022 Korero Press published the Molesworth diaries that appeared in "Punch" between August 1939 and December 1942 in one volume titled 
"The Lost Diaries of Nigel Molesworth". They were illustrated by Uli Meyer in the style of Ronald Searle.

In 1987 the character was reprised for a four-part BBC Radio 4 series, "Molesworth". Written by Simon Brett, the series portrayed Molesworth in middle age, still surrounded by many of the characters from his youth. Molesworth was played by Willie Rushton, with Penelope Nice as his wife Louise, and Clive Swift as the now aged ex-headmaster Grimes.
