The electronic circuits that make up the microprocessors used in computers are made up of small semiconductor elements called transistors. You can find out how transistors work by reading the following article.

The invention that led to the modern transistor was made by a team at Bell Labs, then an AT&T research lab, between 1947 and 1948. Tanenbaum began his career as a researcher in the Scientific Physics Division at Bell Labs in 1952, working with William Shockley , who had done the 1948 research, on whether silicon crystals could be used in transistors.
Tannenbaum and his colleague Ernest Buehler successfully demonstrated the first silicon transistor in 1954. At this point, silicon transistors were not considered suitable for mass production, but in 1955 Tannenbaum succeeded in developing
However, because transistors were not directly related to AT&T's business, Bell Labs did not support Tanenbaum and his colleagues in further transistor research. 'Bell Labs had a big lead in silicon transistor technology, but because it was not immediately relevant to AT&T's business, we stopped doing proper research in this area,' Tanenbaum said in a 1999 interview. 'And silicon transistor technology, including integrated circuits, went to Intel and Texas Instruments instead.'
Tanenbaum continued to conduct various research projects, and in 1962 he was appointed assistant director of the metallurgy department at Bell Labs, where he led the research team that developed the high-field superconducting magnets used in modern medical imaging, including MRIs, as well as the development of fiber optics and digital telephone switching systems.
In addition to his many accomplishments as a scientist, Tanenbaum was also a businessman, having served as president of an AT&T subsidiary in the late 1970s and early 1980s, and then as president of AT&T Communications in 1984. Tanenbaum eventually ended his career as a businessman as vice president and chief financial officer of AT&T.
On February 26, 2023, Tannenbaum passed away at the age of 94 at his home in New Providence , New Jersey.
