bell laboratory in 1947-1948
The transistor was invented by Bell Labs in 1948. Applications in consumer devices followed within a few years after that.

The Bipolar Junction Transistor (BJT) was invented by three scientists, William Shockley, John Bardeen and Walter Brattain, in 1948. They all worked at Bell Labs, and were trying to find something to replace the bulky and heat wasting vacuum tubes. They had been pursuing a Field Effect Transistor (FET) based on copper oxide when they stumbled upon a very different amplifying effect produced by closely-spaced metal contacts touching Germanium semiconductor. They won the Nobel Prize in Physics for their work in 1956. When the Bell Labs scientists continued to investigate a possible FET transistor, they discovered that one of these had already been patented by Physicist J. Edgar Lilienfeld. Lilienfeld's insulated-gate FET (or MOSFET) was based on thin film semiconductor deposited on glass, and was invented over 25 years before the BJT, in the early 1920s.

I know it was BELL laboratory in the fifty I believe
Bell Labs.

The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.

he invented the first transistor
Field Effect Transistor (FET) was invented in 1926 by Julius E. Lilienfeld.
They invented the first transistor.
The transistor
William B. Shockley is best known for co-inventing the transistor in 1947, which revolutionized the field of electronics and led to the development of modern computer technology. This breakthrough technology eventually earned him the Nobel Prize in Physics in 1956.
