The transistor was invented at Bell Labs by William Shockley, John Bardeen and Walter Brattain in 1947.
William Shockley founded Shockley semiconductors. Eight researchers working there, known as the "traitorous eight" left to form Fairchild Semiconductor. Engineers at Fairchild are responsible for many key innovations in semiconductor manufacturing processes.
Gordon Moore, head of R&D at Fairchild left to form Intel in 1968.
... So you could say that Bell Labs indirectly birthed Intel :)
