Electronic circuits, which are the basis of microprocessors installed in computers, are made by combining small semiconductor elements called transistors. You can see how the transistor works by reading the following article.

The invention that led to the modern transistor was made in 1947-1948 by a team at Bell Laboratories, then a research laboratory under AT & T. Tanenbaum began his research career in 1952 at Bell Labs' Scientific Physics Division, under William Shockley , who conducted research in 1948, and began investigating whether silicon crystals could be used in transistors. I was.
Tanenbaum and his colleague Ernest Buehler successfully demonstrated the first silicon transistor in 1954. At this point, silicon transistors were considered unsuitable for mass production, but in 1955 Mr. Tanenbaum succeeded in developing a
However, partly because transistors were not directly related to AT & T's business, Bell Laboratories did not support further transistor research for Tanenbaum et al. In a 1999 interview , Tanenbaum said, 'Bell Labs had a big lead in silicon transistor technology, but stopped doing proper research in this area because it wasn't immediately relevant to AT&T's business. And silicon transistor technology, including integrated circuits, will be handled by Intel and Texas Instruments instead.'
After that, Mr. Tanenbaum continued to conduct various research, and in 1962 he was appointed assistant director of the metallurgical department of Bell Laboratories, and was appointed as a high-field ultrasonographer used for medical diagnostic imaging, including modern MRI. He led the research team that developed the conductive magnet and others. He also supported the development of optical fiber and digital telephone switching systems.
Mr. Tanenbaum, who left many achievements as a scientist, served as president of AT & T's subsidiary in the late 1970s and early 1980s, and in 1984 he became president of AT & T Communications. I'm here. Tanenbaum eventually ended his business career as AT&T's vice president and chief financial officer.
On February 26, 2023, Tanenbaum died at his home in New Providence , New Jersey, at the age of 94.
