This is a replica of the world's first transistor, invented at AT&T Bell Laboratories in 1947. The transistor revolutionized the field of electronics, because it required far less space and consumed less power than a comparable vacuum tube. The implications for aerospace were obvious, although it took many years before reliable transistor circuits were available for air or space operatons.

This is a replica of the world's first transistor, which was made for the Museum by AT&T Bell Laboratories.
