Ronald Searle, the creator of the terrors of St Trinian's, was the most biting satirical cartoonist of his generation.
His work, published worldwide, was in turn outrageously funny, dark and sardonic, and occasionally savage. Some of it was influenced by his years as a Japanese prisoner of war and his privations working on the Siam-Burma Railway of Death.
But he will be best remembered for the unholy girls of St Trinian's, with their spindly, stockinged legs, their ferocious expressions and their dastardly acts of torture.
All this was based on a real school in Edinburgh, St Trinnean's. His creation became an industry almost in its own right and once Searle hoped he had put paid to it by blowing up his fictitious academy with an atomic bomb. But it didn't work. Everybody wanted more St Trinian's.
Ronald William Fordham Searle was born in Cambridge on March 3, 1920. He was drawing creatively at the age of five and professionally at 15.
He became the cartoonist for the Cambridge Daily News, and began a series of 195 weekly cartoons, each of which paid more than a week's salary at the parcel packing business where he had earlier worked.
On the outbreak of World War II he enlisted in the Royal Engineers and trained for two years in the UK. In 1941 he published the first St Trinian's cartoon in the magazine Lilliput.
That year he was posted to Singapore, but one month after his arrival, Singapore surrendered to the Japanese and he spent the rest of the hostilities as a prisoner-of-war.
Even though he was the victim, observer and recorder of atrocities, diseases and deaths, he never stopped drawing, despite beatings, bouts of malaria and beri beri. Once a Japanese guard embedded a pickaxe in his back.
His graphic, grim drawings of camp life were often hidden under the mattresses of prisoners suffering from cholera. He was liberated in 1945 and published the surviving drawings in fellow prisoner Russell Braddon's account of his own captivity The Naked Island.
Once Braddon said of him: "If you can imagine something that weighs six stone or so, is on the point of death and has no qualities of the human condition that aren't revolting, calmly lying there with a pencil and a scrap of paper, drawing, you have some idea of the difference of temperament that this man had from the ordinary human being."
In the 1950s, after failure with two books immediately on demobilisation, Searle produced an extraordinary body of work: drawings for Punch, cartoons for Tribune, the Sunday Express and the News Chronicle, along with more St Trinian books. He created animation for Walt Disney and advertisements, too.
In a remarkably short time he had become one of the foremost illustrators in the country. In one astonishing drawing he depicted a Texan automobile as a riot of carbuncular rococo excrescences making it look "as if it had arrived at that state by some ghastly evolutionary process", according to an admirer.
In 1961, he left a note for his wife Kaye Webb (whom he had married in 1947) and their twins and left for Paris to begin a new life. This was where his Anatomies and Decapitations came to light, a series of 173 violent and disturbing paintings.
He had gone to Paris partly to marry Monica Koenig, a woman he had met earlier. But he continued his work, including cat books, animation for films and designs for medals.
In 1971, he became the first non-French living artist to exhibit at the Bibliotheque Nationale. Four years later the Searles left Paris to a new and more secluded life in Haute-Provence.
One friend said of him: "His bite and his bark were ferocious, but always delivered with a wink."
