Stars were first classified by brightness by Hipparchus in 129 BC.  He produced the first well known catalog of stars in which the brightest stars were listed as "first magnitude" and the second grouping was "second magnitude".  This division went up to sixth magnitude.<ref>http://skytonight.com/howto/basics/3304516.html</ref>
