\Quak"er\, n.
1. One who quakes.
2. One of a religious sect founded by George {Fox}, of
   Leicestershire, England, about 1650, -- the members of
   which call themselves Friends. They were called Quakers,
   originally, in derision. See {Friend}, n., 4.
         Fox's teaching was primarily a preaching of
         repentance . . . The trembling among the listening
         crowd caused or confirmed the name of Quakers given
         to the body; men and women sometimes fell down and
         lay struggling as if for life.        --Encyc. Brit.
