March 5: The Museum in Washington, DC will open today. Due to weather, the Udvar-Hazy Center in Chantilly, VA is closed.

Transistor, Replica of World's First

The transistor, invented at Bell Telephone Laboratories in 1947, 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.
