## Leigh Mercer

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

The following mathematical limerick is attributed to him: :$\frac\left\{12 + 144 + 20 + 3 \sqrt\left\{4\right\}\right\}\left\{7\right\} + \left(5 \times 11\right) = 9^2+0$ 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.
