Clerihew: A form of whimsically biographical comic verse.

G K Chesterton called it a “severe and stately form of free verse”, but then he had been a close friend from schooldays of the man who invented it, Edmund Bentley. Indeed, Chesterton illustrated the first book of whimsical verses, Biography for Beginners, which Bentley published in 1905 under the name of E. Clerihew.

The form is slight but not slighting, conventionally consisting of a quatrain with the name of the biographee as the first line. The lines are of unequal lengths, rhymed AABB, often written in a flat-footed or mangled way more reminiscent of prose than verse. The first, which Edmund Bentley is said to have composed during a boring science class at St Paul’s School, was:

Sir Humphry Davy
Abominated gravy.
He lived in the odium
Of having discovered sodium.

Clerihew was Bentley’s middle name, which was given him (and which he in turn passed to his son Nicholas) to mark his mother’s maiden name, Margaret Richardson Clerihew, Clerihew being an old Scottish surname. It was applied to the verse form by others and seems to have first surfaced in its own right as the name in 1928.
