GENERAL KNOWLEDGE

Detailed explanation-1: -The transistor, however, is an invention that was conceived long before the time was right. It was invented in 1947, and even several years later, it was considered by a scientific conference to be such an odd accomplishment that it was not included in the documentation.

Detailed explanation-2: -John Bardeen, Walter Brattain and William Shockley invented the first working transistors at Bell Labs, the point-contact transistor in 1947. Shockley introduced the improved bipolar junction transistor in 1948, which entered production in the early 1950s and led to the first widespread use of transistors.

Detailed explanation-3: -In 1947, the transistor, arguably the most important invention developed by Bell Laboratories, was invented by John Bardeen, Walter Houser Brattain, and William Bradford Shockley (and who subsequently shared the Nobel Prize in Physics in 1956).
