Sunday January 31, 2021
1:30 PM - 3:00 PM

Dr. Allen will begin with the earliest history of vacuum tubes, describing the Edison Effect, and how Ambrose Fleming and Lee de Forest's inventions exploited this to create the first functioning vacuum tubes. We will review the basic theory of tubes as we move on to the pioneering developments at companies like GE, Bell Telephone, and RCA, including Edwin H. Armstrong's circuits. These creations revolutionized communication and led to our modern age of electronics.
