The first located Brown Dwarf was discovered in 1988 as a companion to the star GD 165, which was too cool to be classified as an M class star.  For almost a decade, GD 165B, today known as a L class brown dwarf was the only known object that could be classified as such.  1995 using a combination of mass determination, spectroscopic studies, and direct imaging another confirmed brown dwarf was discovered as a companion to [[Gliese 229]].  The discovery would later help establish a new class of brown dwarfs known as "T dwarfs".  Today hundreds of brown dwarfs are known<ref name="bdref">http://www.daviddarling.info/encyclopedia/B/browndwarf.html</ref>.
