A person who makes or sells blankets, or historically, a person who wore a blanket as clothing.
From blanket plus -eer (a suffix from French -ier meaning 'one who works with'). Similar formations include 'auctioneer' and 'profiteer.' The term is now rare or archaic.
This word shows how English borrowed the French -eer suffix to describe trades and occupations—like 'musketeer' (one who uses a musket) or 'racketeer' (one involved in racketeering). Most blanketeers are long retired from history.
