bobby
Preserved but no longer current.
A policeman: both BOBBY and PEELER were nicknames given to the new police, in allusion to the Christian name and surname of the late Sir Robert Peel, who was the prime mover in effecting their introduction and improvement. The term BOBBY is, however, older than the introduction of the new police. The official square-keeper, who is always armed with a cane to drive away idle and disorderly urchins, has, time out of mind, been called by the said urchins, "BOBBY the beadle."
Era: ca. 1874 (Victorian)
