One of the literary forms that has always given me most pleasure, in between the serious stuff, has been the clerihew, named after its inventor Edmund Clerihew Bentley (1875–1956). Bentley was chief leader writer for the Daily Telegraph from 1912 to 1934. In 1905, a decade before he produced another of his inventions, the modern detective novel, with Trent’s Last Case, he published a slim volume entitled Biography for Beginners, which opens, under the heading ‘Introductory Remarks’, with this four-liner: The Art of Biography / Is different from Geography. / Geography is about Maps, / But Biography is about Chaps.
