Bell Labs has been in operation in the United States since 1925, originally as part of Western Electric, and later, AT&T.  Today, Bell Labs is part of the innovation engine for Alcatel-Lucent.

Headquarters was in New York until 1941, when the world headquarters for Bell Labs moved to Murray Hill, N.J., where it remains today.  

Our U.S. locations have been the site of seminal inventions such as the transistor, Unix, and the laser, as well as the research hub for many projects related to electronic switching, data communications, and optical transmission. Radio astronomy was born at Bell Labs in the early 1930s and the Horn Antenna, the device used in Nobel prize-winning work that recorded cosmic background radiation from the Big Bang is a national historical landmark at one of our New Jersey facilities.

Bell Labs researchers work in several locations across the United States, including: 

  • Murray Hill, New Jersey
  • Holmdel (Crawford Hill), New Jersey
