Thomas Alva Edison
=======================
The true villain of the piece is Lee DeForest who introduced a control grid into a thermionic diode tube, and thus prevented the invention of the transistor for a half century. At that time, electronic technology was getting nosey about point contact diodes and double point contact diodes which were about to morph into transistors, but that all stopped with the invention of the "Audion tube" (aka triode) in 1908.
the vacuum tube
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
Millman's theorem
who made the vacuum tubes
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
an electron tube containing a near-vacuum that allows the free passage of electric current.

Vacuum tubes are typically evacuated of gases to create a vacuum inside. However, some specialized vacuum tubes may use inert gases like argon or neon to improve performance or provide specific characteristics.
In 1907 American inventor Lee De Forest invented the three-electrode vacuum tube
