Please answer the following question: What is the last name of the person who introduced the single column-width cartoon popular in the French press but not until then seen in British papers?  Answer the above question based on the context below:  Sir Osbert Lancaster, CBE (4 August 1908 – 27 July 1986) was an English cartoonist, architectural historian, stage designer and author. He was known for his cartoons in the British press, and for his lifelong work to inform the general public about good buildings and architectural heritage.  The only child of a prosperous family, Lancaster was educated at Charterhouse School and Lincoln College, Oxford, at both of which he was an undistinguished scholar.

From his youth, Lancaster wanted to design for the theatre, and in 1951 he was commissioned to create costumes and scenery for a new ballet, Pineapple Poll. Between then and the early 1970s he designed new productions for the Royal Ballet, Glyndebourne, D'Oyly Carte, the Old Vic and the West End.
