St Trinian's is a British gag cartoon comic strip series, created and drawn by Ronald Searle from 1946 until 1952.
Whilst visiting the family Johnston, he made a drawing to please their two schoolgirl daughters, Cécilé and Pat, (their school had been evacuated to New Gala House in Galashiels in the Scottish Borders owing to the war).
Searle was puzzled as to why two schoolgirls should seem so keen to return to their school, an Academy for Young Ladies in Dalkeith Road known as St Trinnean's.
[7] During his BBC interview[8] Searle agreed that the cruelty depicted at St Trinian's derived partly from his captivity during World War II but stressed that he included it only because the ignoble aspect to warfare in general had become more widely known.
In the 1950s, a series of St Trinian's comedy films were made, featuring well-known British actors, including Alastair Sim (in drag as the headmistress, and also playing her brother); George Cole as spiv "Flash Harry", Joyce Grenfell as Sgt Ruby Gates, a beleaguered policewoman; and Richard Wattis and Eric Barker as the civil servants at the Ministry of Education for whom the school is a source of constant frustration and nervous breakdowns.
Barchester and Barset were used as names for the fictional towns near which St Trinian's School was supposedly located in the original films.
It is something of a rule of thumb that the smaller a St Trinian's is, the more dangerous she is—especially when armed, most commonly with a lacrosse or hockey stick—though none of them can ever be considered harmless.
The cast included Rupert Everett, Colin Firth, Russell Brand, Lily Cole, Talulah Riley, Stephen Fry, and Gemma Arterton.
The lyrics of the original theme song by Sidney Gilliat (c. 1954) imply that the school's motto is "Get your blow in first"[11] (Semper debeatis percutis ictu primo).
The musical score for the St Trinian films was written by Malcolm Arnold and included the school song, with words accredited to Sidney Gilliat (1954).
