Joshua Charles Armitage (26 September 1913 – 29 January 1998) was an English illustrator under the pen name Ionicus.
[1][2] Ionicus may be known best for illustrating the covers of Penguin paperback editions of books by P. G. Wodehouse, though he contributed cartoons and drawings to Punch for more than 40 years, and provided cover designs and text illustrations for nearly 400 books in total.
[3] Armitage was born in 1913, in the town of Hoylake on the Irish Sea, county of Cheshire.
He took the name Ionicus for his first cartoon that was published in Punch, 29 March 1944, after two ionic columns in the drawing.
[2] Although best known for his depiction of Wodehouse's idyllic England, Ionicus also provided dustjacket illustrations for well-known writers in other genres, such as the following: During his wartime service in the British Navy, Ionicus contributed to the Admiralty-sponsored monthly magazine Ditty Box.
