After beginning his career at Bell Labs in 1955 working on TRADIC, one of the first transistorized digital computers, John Mayo went on to pioneer the use of transistors in what would become the T-1 Carrier System.
His other research was associated with the development of high-speed pulse-code modulation systems, the Telstar satellite program, the development of electronic systems for ocean sonar and the development of the world’s first long-distance digital switching system. In 1991 he became the seventh president of Bell Labs, where he oversaw significant programs in fiber optics, wireless and video.
Dr. Mayo was a recipient of the US National Medal of Technology, the C&C Award from the NEC Corporation and the American Association of Engineering Societies Chair Award An IEEE Fellow, he was elected to the National Academy of Engineering in 1979. He earned a PhD in electrical engineering from North Carolina State University.
Ian Ross began his career at Bell Labs in 1952, when William Shockley hired him to conduct semiconductor research.
He was actively involved with early research on the field-effect transistor and then with epitaxy, the process for growing specialized silicon crystals. Ross oversaw the research associated with the electronics for Telstar, the first communications satellite.
In 1964, he was named managing director of Bellcomm, a Bell System unit formed solely to plan Apollo moon missions. Soon after returning to Bell Labs, he became its sixth president. Ross oversaw the reorganization of Bell Labs in the aftermath of the break-up of the Bell System in 1984.
Dr. Ross was a member of the National Academy of Engineering, National Academy of Sciences, and Royal Academy of Engineering and a fellow of the American Association for the Advancement of Science and the Institute of Electrical and Electronics Engineers. He attended Cambridge University, attaining a PhD in electrical engineering in 1952.
An advisor to five U.S. presidents and member of several presidential committees and boards, William O Baker was a prominent voice on scientific policies and issues.
After attaining a PhD in chemistry from Princeton University, he joined Bell Labs in 1939. His research focused on polymers and the crystalline molecular structure of various materials, including plastics and natural rubber.
His work in the late 1930s and early 1940s helped perfect the process for manufacturing synthetic rubber. He served as the first vice president of research from 1955 until 1973, when he was appointed as president of Bell Labs.
Dr. Baker was a recipient of the US Medal of Science and the Marconi Society’s Lifetime Achievement Award; he was appointed a Fellow of the American Academy of Arts and Sciences, and was the first recipient of what would subsequently be named the William Oliver Baker Award from the US Intelligence and National Security Alliance. He received eleven patents for his research.
Dr. Baker served as a member of the US President’s Science Advisory Committee, the President’s Foreign Intelligence Advisory Board and the Federal Emergency Management Advisory Board.
James Fisk became Bell Labs’ fourth president in 1959. His foresight of the coming information revolution led to the acceleration of projects that ushered in the digitalization of communications.
Fisk earned a PhD in Theoretical Physics from the Massachusetts Institute of Technology in 1935. Prior to joining Bell Labs in 1939, he had taught physics at the University of North Carolina and the Massachusetts Institute of Technology.
At Bell Labs he soon found himself leading several projects related to radar, including one directed towards the practical production and improvement of the magnetron that had been invented in Great Britain.
At the end of World War II, Fisk was appointed assistant director of physical research in charge of electronics and solid-state research. He directed the researchers who two years later would invent the transistor. In 1947, he was recruited from Bell Labs to serve as the first director of research for the US Atomic Energy Commission, and then as a professor in Applied Physics at Harvard University. Dr. Fisk returned to Bell Labs in 1949 as head of physical research.
Among his many achievements, Dr. Fisk was a member of the U.S. National Academy of Sciences, served on the U.S. President’s Science Advisory Committee, and in 1958 was appointed by Dwight D. Eisenhower to head the U.S. delegation to the Geneva conference of experts on a nuclear test ban.
Upon earning his PhD in physics at the University of Chicago, Mervin Kelly began his Bell System career in 1917 working with vacuum tube technology.
In the years that followed, perhaps more than anyone else, he crafted and refined the research model that would define Bell Labs. Kelly personally hired talent such as William Shockley and James Fisk. He pioneered the methods of industrial research, of “inventing ways to invent things.” His toolkit included cross-disciplinary teams of experts, close proximity between researchers and developers and even ways to design buildings to encourage collaborations. By 1926, he became director of research, in 1944 executive vice president, and in 1951 president of Bell Labs.
As president of Bell Labs between 1940 and 1951, Oliver Buckley piloted Bell Labs through the frantic pace of research during the war years, and the rapid period of growth that followed.
Buckley joined the Bell System after completing his PhD in physics at Cornell University in 1914. His early research there in undersea sound detection and signal analysis launched a three-decade quest for advances in submarine cables and a record of outstanding technical leadership. In 1933, he was appointed the director of research at Bell Labs, and in 1936 became its executive vice president. Buckley was a member of the US National Academy of Sciences and a fellow of the American Academy of Arts and Sciences, the American Physical Society and the American Institute of Electrical Engineers.
Frank Jewett was the ideal candidate for the role of first president of the newly created Bell Labs in 1925. Frank Jewett believed that the best science and technology result from bringing together and nurturing the best minds. He worked diligently to acquire an extraordinary collection of scientists and then provided them with the support to create the breakthroughs that defined the industry.
Jewett graduated from Throop Polytechnic Institute (later renamed California Institute of Technology,) then attended the University of Chicago, where he was awarded a doctoral degree in physics. After teaching at the Massachusetts Institute of Technology, he joined the Mechanical Department of AT&T in 1904. Jewett’s involvement with electronic tubes and transatlantic radio communications, along with his experience in the Signal Corps during the First World War convinced him that industrial research was coming of age and moving beyond the “cut-and-try methods” that had prevailed in most other industrial labs. He saw a far closer linkage with university-based pure science — but also understood the differences.
