The vacuum tube was invented in 1906 and was the enabling technology for the rapid development of electronics for the next 50 or so years until the appearance of the transistor in the late 1950's.

This film from Philips-Mullard (1948) presents a detailed look at the components, construction, and manufacture of vacuum tubes.  This is a fascinating work on several levels - vacuum tube technology, period manufacturing automation, and the factory environment itself (25.26 minutes).
