Please note: your email address and contact information will be masked on the website for privacy reasons. Only IEEE History Center Staff will be able to view the email address.

Street address(es) and GPS coordinates of the intended milestone plaque site(s):

Alcatel-Lucent Bell Labs, 600 Mountain Avenue, Murray Hill, New Jersey 07974

Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.

Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need.

In the lobby of the Hall of Innovation museum adjacent to the lobby of Building 6, Alcatel-Lucent Bell Labs, 600 Mountain Vae, Murray Hill, NJ

Are the original buildings extant?


Details of the plaque mounting:

In the entrance hall lobby

How is the site protected/secured, and in what ways is it accessible to the public?

The Alcatel-Lucent Bell labs 6 lobby and the Hall of Innovation have security protection. The building lobby is accessible to the public at the milestone dedication ceremony and during business hours according to Alcatel-Lucent building security procedures.

Who is the present owner of the site(s)?

Alcatel-Lucent Bell Labs

What is the historical significance of the work (its technological, scientific, or social importance)?

Bell Labs transformed the way people communicate at work and home through the invention and development of many technical innovations that were necessary for the modern tele-communication systems and other advanced technologies. From its founding in 1925, Bell Telephone Laboratories made numerous significant contributions to telecommunications and related fields that led to the information age and the digital era. Some of these contributions include: information theory, systems engineering, digital signal processing, digital transmission and switching, data networking, cellular systems, (800) service, the transistor, solar cell, integrated circuit technology, communication satellites, high capacity undersea cable, touch-tone dialing, voice and video compression, and the Unix operating system.

Summary description of the breadth of some of the contributions of Bell Telephone Laboratories: Information Theory was developed by Claude E. Shannon at Bell Telephone Laboratories to find fundamental limits on signal processing operations such as compressing data and on reliably storing and communicating data. It is the fundamental underpinnings of modern computer and communications technology.

Systems engineering is the interdisciplinary field of engineering that focuses on how complex engineering projects should be designed and managed over the life cycle of the project. It originated in Bell Telephone Laboratories in the 1940s for the development and implementation of complex systems. It is widely used by companies and government organizations. The NASA Apollo Project and the International Space Station is an example of such systems.

The UNIX operating System and C programming language were created at Bell Labs between 1969 and 1972. UNIX made large-scale networking of diverse computing systems - and the Internet - practical. UNIX and its spin-offs are the operating system of most large computers, Internet servers, and smart phones. The C language brought an unprecedented combination of efficiency and expressiveness to programming. C and its descendants are the most widely used programming languages in the world.

The Transistor was invented in 1947 as a replacement for bulky and inefficient vacuum tubes and mechanical relays. The transistor revolutionized the entire electronics world. The transistor sparked a new era of modern technical accomplishments from manned space flight and computers to portable radios and stereos. As embodied in integrated circuits, it is the basic building block of modern electronics and is manufactured by the multi- billions every year.

The first practical Solar cell was developed in Bell Labs in 1954. It converts the sun’s energy into electricity. It was first used on a large scale for satellites and is now an important factor in the sustainable creation of electricity.

Cellular systems were first proposed in 1947 Bell Labs publications. The primary innovation was the development of a network of small overlapping cell sites supported by a call switching infrastructure that tracks users as they moved through a network and pass their call from one site to another without dropping the connection. Bell Labs installed the first commercial cellular network in Chicago in the 1970s. Today, it is the basis of a rapidly growing cellular and mobile smart phone industry.

Thefirst high capacity transatlantic telephone cable, which was based on innovations from Bell Labs, was deployed in 1956. Bell Labs was the pioneer in communications satellites. In 1962 it built and successfully launched the first orbiting active communications satellite (Telstar I), which transmitted the first live television across the Atlantic.

Digital transmission and electronic switching; In 1962, Bell Labs developed the first digitally multiplexed transmission of voice signals. This innovation not only created a more economical, robust and flexible network design for voice traffic, but also laid the groundwork for today's advanced network services such as 911, 800-numbers, call-waiting and caller-ID. In addition, digital networking was the foundation for the convergence of computing and communications.

LASER; The invention of the laser, which stands for “Light Amplification by Stimulated Emission of Radiation,” originated in 1958 with the publication of a scientific paper by Bell Labs researchers. Lasers launched a new scientific field and opened the door to a multibillion-dollar industry that includes applications in medicine, communications, and consumer electronics.

Bell Labs built the first single-chip digital signal processor in 1979. The DSP is the engine of today's multimedia revolution. DSP technology is in multimedia PCs and in the modems that connect computers to the Internet. It's in wireless phones, answering machines, and voice-mail; it's in video games talking toys, DVD players and digital cameras.

What obstacles (technical, political, geographic) needed to be overcome?

As a regulated monopoly, Bell Labs had to share its innovations with others under terms of the federal government's regulatory agreements.

What features set this work apart from similar achievements?

References to establish the dates, location, and importance of the achievement: Minimum of five (5), but as many as needed to support the milestone, such as patents, contemporary newspaper articles, journal articles, or citations to pages in scholarly books. At least one of the references must be from a scholarly book or journal article.
