Peelers

Policemen. The word goes back to the English statesman Sir Robert Peel (1788-1850), who established the metropolitan police force in England. He became Prime Minister in 1841 and served in that office for five years (105). Brewer (56) adds that the nickname “Bobby” was derived from Peel’s first name.
