Dedicated to Preserving the History and Future of Vacuum Tubes

The International Vacuum Tube Museum is dedicated to being the preeminent international organization devoted to the collection, study, education, exhibition, research, conservation, interpretation, preservation and documentation of vacuum tubes and vacuum tube artifacts. Vacuum tubes are the foundation for radios, televisions, computers… all electronic devices in the modern age.

The Museum and our team are proud members of the following organizations:Member of the America Alliance of Museums

  • Alliance of American Museums (AAM)
  • American Association for the Advancement of Science (AAAS), Sections: Physics, Engineering, History and Philosophy of Science
  • American Association for State and Local History (AASLH)
  • American Library Association (ALA)

    New exhibitions are being built at our new facility in Lakewood Colorado, and our website is being completely redesigned!

Vacuum Tubes: History

  • November 16, 1904. Happy Birthday to the Vacuum Tube!
    On this day, Sir John Ambrose Fleming invented the Fleming valve, the first thermionic valve, now known as the vacuum tube. Sir Fleming is widely considered to be the father of modern electronics, and his invention is the foundation for radios, televisions, computers… all electronic devices.
  • October 20, 1906. The Triode Tube
    On this day, Dr. Lee de Forest presented his paper, “The Audion. A New Receiver for Wireless Telegraphy.” to the American Institute of Electrical Engineers.
  • 1950
    Vacuum Tube Trains were predicted in 1950 (Now called the Hyperloop)

Vacuum Tubes: Future

Vacuum Tubes: Present

  • World’s First Terahertz Vacuum Amplifier Created
    “Vacuum tubes bring back visions of antique electronics, but these are not your grandparents’ TV sets. DARPA-sponsored research has taken tools developed by the semiconductor and MEMS revolution–microfabrication methods and materials–and applied them to reliable, efficient vacuum tube technologies.” Learn more
