The transistor was invented by Bell Labs in 1947. The people responsible for the discovery, John Bardeen, [William Shockley]?, and [Walter Brattain]?, won the Nobel Prize in Physics in 1956.

Bell Labs developed the [photovoltaic cell]?.

Bell Labs was also the original home to the UNIX operating system and the C programming language, developed by Brian Kernighan, Dennis Ritchie, and Ken Thompson in the early 1970s, as well as the C++ programming language developed by Bjarne Stroustrup in the 1980s.
*In 1933, [Karl Jansky]? in his work for Bell Labs investigating the origins of static on long distance communications, discovered that radio waves were being emitted from the centre of the Galaxy - the founding of [Radio astronomy]?, though Bell did not pursue this, being more focussed on the problems of telecommunications.
