This specific copy of the journal was presented to Morris Tanenbaum, whose name is embossed on the front cover. Tanenbaum was a prominent Bell Labs scientist and future Chairman of AT&T Communications (see below.)

This issue of the BSTJ commemorates the half-century of groundbreaking telecommunications research initiated by founders in July 1922.
The lead article, "Fifty Years of BSTJ", reviews the journal's mission set forth in Volume 1, Number 1. It highlights how telecommunication demanded the constant application of the scientific method, which in turn expanded the boundaries of global human knowledge.

The article reviews some of the important papers published in the journal during its first 50 years.

The issue features several foundational articles for computing, networking, and signal processing:
"Network for Block Switching of Data" (J.R. Pierce): Introduced the "Pierce Loop," an early packet/block switching concept for data transmission over local and national rings.
"An Experimental Data Block Switching System" (W.J. Kropfl): Detailed the practical implementation of the Pierce Loop network.
"The Design of Finite Impulse Response Digital Filters Using Linear Programming Techniques" (L.R. Rabiner): A seminal paper in digital signal processing (DSP).
"Synthesis of Voiced Sounds From a Two-Mass Model of the Vocal Chords" (K. Ishizaka & J.L. Flanagan): Advanced the state of the art in speech synthesis and acoustics. Morris Tanenbaum (November 10, 1928 – February 26, 2023) was an American physical chemist and executive who worked at Bell Laboratories and AT&T Corporation.

Tanenbaum made significant contributions in the fields of transistor development and semiconductor manufacturing. Although it was not made public at the time, he developed the first silicon transistor, demonstrating it on January 26, 1954, at Bell Labs.[1][2] He also helped develop the first gas-diffused silicon transistor, which convinced Bell administrators to prefer the use of silicon rather than germanium in their transistor design. He later led a team that developed the first high-field superconducting magnets.

Later in his career he became an executive. He dealt with the separation of Bell Laboratories and AT&T, and became the first chief executive officer and chairman of the board at AT&T Corporation on January 1, 1984.

Early life and education
Morris Tanenbaum was born to Ruben Simon Tanenbaum and Mollie Tanenbaum, on November 10, 1928, in Huntington, West Virginia, US. Tanenbaum's parents were Jewish, and had emigrated from Russia and Poland, first to Buenos Aires, Argentina and then to the United States. Ruben Tanenbaum owned a delicatessen. Career Morris Tanenbaum joined the chemistry department at Bell Telephone Laboratories in 1952. He held a number of positions at Bell, beginning in the technical staff from 1952 to 1956, becoming assistant director of the metallurgical department until 1962, then director of the solid-state development laboratory until 1964. He was executive vice-president for systems engineering and development from 1975 to 1976.

Tanenbaum then moved to the Western Electric Company, where he worked as director of research and development (1964–1968), vice president of the engineering division (1968–1972) and vice president of manufacturing: transmission equipment (1972–1975).

He returned to Bell Laboratories in 1975 as vice President of engineering and network services from 1976 to 1978. He served as president of the New Jersey Bell Telephone Company from 1978 to 1980, then returned to Bell Laboratories as Executive Vice President for Administration from 1980 to 1984.[4] On January 16, 1985, he was appointed "corporate executive vice president responsible for financial management and strategic planning".Concerns that AT&T and Bell Laboratories effectively held a monopoly on communication technology throughout the United States and Canada led to an antitrust case, United States v. AT&T, and the eventual breakup of the Bell System. Tanenbaum was closely involved in discussion of related senate legislation, and helped to draft the proposed "Baxter I" amendment.

Following the restructuring, Tanenbaum became the first chief executive officer and chairman of the board at AT&T Communications from 1984 to 1986. From 1986 to 1988 he served as AT&T's Vice Chairman for Finance, and from 1988 to 1991, AT&T's vice chairman for finance and chief financial officer.

Research
[First silicon transistor,br> On January 26, 1954, Tanenbaum recorded a successful demonstration of the first silicon transistor in his logbook. However, Bell Laboratories did not publicise Tanenbaum's discovery—the successful transistor had been constructed using a rate-growing process, which was felt to be poorly suited to large-scale manufacturing. Diffusion processes, pioneered by Bell's Calvin Fuller, were seen as more promising. Tanenbaum became the team leader for a group studying the possible application of diffusion to the fabrication of silicon transistors.

The first gas-diffused silicon transistor
By 1954, several researchers at Bell Labs were experimenting with diffusion techniques to create layered semiconductors. Charles A. Lee developed a germanium semiconductor using diffused arsenic in late 1954.[18] Meanwhile Tanenbaum worked with Calvin Fuller, D. E. Thomas, and others to develop a gas diffusion method for silicon semiconductors. Fuller developed a way to expose thin slices of crystalline silicon to gaseous aluminum and antimony, which diffused into the silicon to form thin multiple layers.[16]Tanenbaum needed to establish a reliable electrical contact with the middle layer.

After weeks of experimenting, Tanenbaum wrote in his laboratory notebook on March 17, 1955, "This looks like the transistor we’ve been waiting for. It should be a cinch to make." The diffused-base silicon transistor was able to amplify signals at frequencies above 100 megahertz, with a switching speed 10 times faster than previous silicon transistors. The news convinced executive Jack Andrew Morton to return early from a trip to Europe and adopt silicon as the material for the company's future transistor and diode development.

In 1956, with financial backing from Arnold Beckman, William Shockley left Bell Labs to form Shockley Semiconductor. Shockley made Tanenbaum an offer but Tanenbaum chose to stay with Bell Labs. The n-p-n silicon transistors created with the double-diffusion method were referred to as "mesa transistors" as they had a raised area or "mesa" above the surrounding layers of etching. The initial goal at Shockley Semiconductor was to fabricate prototype n-p-n silicon transistors, based on the "mesa" structure pioneered by Tanenbaum and his co-workers at Bell Labs.By May 1958 Shockley's employees had successfully met that goal.

Bell Laboratories did not take advantage of Tanenbaum's early achievements by capitalizing on the possibilities of chip technology. They became increasingly dependent on other companies for microchips and large-scale integrated circuits. Tanenbaum expressed disappointment at this missed opportunit.

High-field superconducting magnets
Tanenbaum and Kunzler's group created the first high-field superconducting magnets, showing that Nb3Sn exhibits superconductivity at large currents and strong magnetic fields. Nb3Sn became the first known material suitable for use in high-powered magnets and electric machinery.[29][30] Their discovery made possible the eventual development of medical imaging devices.

Tanenbaum eventually moved from research into management, a change in focus that some speculate may have cost him a Nobel Prize.

Death Tanenbaum died in his home in New Providence, New Jersey, on February 26, 2023.

Awards and honors
In 1962, Tanenbaum became a Fellow of the American Physical Society.

In 1970, he became a fellow of the Institute of Electrical and Electronics Engineers (IEEE).[4] In 1972, Tanenbaum was elected a member of the National Academy of Engineering, for "Achievements in solid state research and technology and in technology transfer from research to manufacturing."[33] In 1984 he received the IEEE Centennial Medal.

In 1990 Tanenbaum became a member of the American Academy of Arts and Sciences (AAAS).[34] In 1996 he became a life member of the MIT Corporation, the board of trustees of Massachusetts Institute of Technology.  He received multiple honorary doctorates.

In 2013, Tanenbaum received a lifetime achievement award, the Science and Technology Medal, at the 34th Edison Patent Awards which are given by the Research & Development Council of New Jersey.
