Point-contact transistor (BJT, 1947)
The first working one in 1947 by
John Bardeen
and
walter Brattain
in
Bell Labs Murray Hill
.
People had already
patented
a lot of stuff before without being able to make them work. Nonsense.
As the name suggests, this is not very sturdy, and was quickly replaced by
bipolar junction transistor
.
