Leigh Mercer

Leigh Mercer (1893–1977) was a noted British wordplay and recreational mathematics expert.[1] He is best known for devising the palindrome "A man, a plan, a canal — Panama!".[2]

The following mathematical limerick is attributed to him:[3]

This is read as follows:

A dozen, a gross, and a score
Plus three times the square root of four
Divided by seven
Plus five times eleven
Is nine squared and not a bit more.
