'''Bell Laboratories''' (usually '''Bell Labs''') was the research arm of the Bell system. It did basic research in fields useful to Bell (Bells Labs researchers received numerous Nobel prizes in physics), as well as applied research, but its primary purpose was to develop telecommunications gear for the Bell system.

Among notable achievements of Bell Labs were important early work on [[semiconductor]]s (the key technology in all of modern [[electronic]]s - in the late 1930s); the [[transistor]] (in 1947); and [[UNIX]] (in the early 1970s).

Bell Labs as an independent company was set up as subsidiary of AT&T in 1925, and moved to Murray Hill, New Jersey.
