Who Invented Vacuum Tube Computers?
In the early days of computing, vacuum tube technology was the foundation upon which computers were built. These tubes, also known as valves, were electronic components that controlled the flow of electrons in a circuit. They were bulky, inefficient, and prone to failure, but they were the only technology available at the time that could perform the necessary computations.
The First Vacuum Tube Computer
The first vacuum tube computer was invented in 1937 by John Atanasoff and Clifford Berry. It was known as the Atanasoff-Berry Computer and was capable of solving systems of simultaneous linear equations. Although it was not a general-purpose computer, it laid the foundation for the development of electronic computers.
The Atanasoff-Berry Computer was different from earlier mechanical computers, which used gears, levers, and other physical components to perform calculations. Instead, it used electronic circuits, including vacuum tubes, to perform its calculations. This made it much faster and more efficient than mechanical computers, which could only perform a limited set of operations.
The Atanasoff-Berry Computer was also noteworthy for its use of binary digits, or bits, to represent numbers. Binary digits are a system of counting that uses only two digits, typically 0 and 1. This system is the foundation of modern computing and is used by all electronic computers today.
ENIAC Computer
The Electronic Numerical Integrator and Computer (ENIAC) was the first general-purpose electronic computer. It was also the first computer to use vacuum tubes extensively. ENIAC was invented by J. Presper Eckert and John Mauchly and was operational in 1945. ENIAC was used primarily for military purposes, such as calculating ballistic trajectories and designing atomic weapons.
ENIAC was a massive computer that weighed over 27 tonnes and used around 18,000 vacuum tubes. It was also incredibly expensive to operate, consuming over 160 kilowatts of electricity per hour. Despite these limitations, ENIAC was a significant breakthrough in computing technology and laid the foundation for the development of modern electronic computers.
EDVAC
The Electronic Discrete Variable Automatic Computer (EDVAC) was invented by John von Neumann. It is widely considered to be the prototype of all modern computers and was the first computer to store a program in its memory. EDVAC was operational in 1952 and was used for scientific and military purposes, such as calculating the trajectories of guided missiles.
EDVAC was a significant improvement over ENIAC, as it used a technique called "stored-program computing." This allowed the computer to store information in its memory and process it later, which made it much faster and more flexible than previous computers.
EDVAC also used vacuum tubes extensively, with over 6,000 tubes used in its construction. Despite its technological advancements, EDVAC was still limited by its use of vacuum tube technology, which was bulky and unreliable. However, it paved the way for further advancements in computing technology and set the stage for the development of the first transistor-based computers in the late 1950s.
In conclusion, the invention of vacuum tube computers was a significant breakthrough in computing technology. It allowed computers to perform calculations faster and more efficiently than ever before, paving the way for the development of modern electronic computers. While vacuum tube technology has since been replaced by more advanced technologies, its impact on computing technology cannot be overstated.

Although the ABC was not considered a general-purpose computer, it laid the foundation for the subsequent development of vacuum tube computers.
Mauchly and Eckert
In 1945, J. Presper Eckert and John Mauchly of the University of Pennsylvania unveiled the Electronic Numerical Integrator and Computer (ENIAC), which was the first general-purpose electronic computer. The ENIAC was enormous, occupying a whole room and using over 17,000 vacuum tubes. However, it was capable of performing complex calculations much faster than previous mechanical or electromechanical computers.
