1. The Inventor of the First Computer: Who
Was It?
Who made the first computer? This might seem like an easy question to answer,
but it isn’t! Different sources credit different inventors with creating the first
computer, and it’s hard to know which ones to trust when they are all so old and
have been passed around by word of mouth since then. In this article, we’ll
discuss what information we do know about the inventors of the first computer
and why their contributions were so important. First, let’s start with the basics –
what exactly was the first computer?
Charles Babbage
The first computer was built in 1822 by Charles Babbage, a mathematician. He
developed a machine called the difference engine that was designed to calculate
mathematical tables using a concept now known as binary code. Today, we use
computers and binary code to carry out many computing tasks; Babbage’s engine
is considered to be one of history’s first computers, but it was never built in his
lifetime.

2. George Stibitz
The man who invented ENIAC, one of history’s first programmable computers, is
George Stibitz. While working at Bell Labs in New Jersey in 1939, Stibitz was
tasked with calculating ballistic trajectories for U.S. Army missiles and rockets. For
such calculations to be done quickly—and accurately—Stibitz needed a fast and
reliable way to move numbers from one place to another on a digital display.
Howard Aiken
Howard Hathaway Aiken was an American physicist, engineer and inventor best
known for his work on early computers. He was a recipient of many honors
including, in 1985, National Medal of Science. Aiken’s research on large-scale
digital computing led to him being called the father of modern computing as well
as to computers being named after him (the Mark I computer). He was born into a
farming family and brought up in Worcester, Massachusetts.
Konrad Zuse
Today, computers are ubiquitous in our lives, but it wasn’t always that way. If you
trace back their roots to earlier times, you can find that they were originally
created to help with math-related calculations and data storage during World
War II. The person who invented one of these first computers was Konrad Zuse.
He designed a programmable, electromechanical machine called Z1 in 1938.
Lee de Forest
Most historians credit Lee de Forest with inventing radio as we know it today. De
Forest developed, patented, and marketed both an improved Audion (Triode)
vacuum tube and a device that used these tubes to transmit wireless signals over

3. long distances. Called a radio telephone, it was one of two wireless systems that
competed for commercialization in 1912. The other was Marconi’s Wireless
Telegraph Company, which had by then merged with major telegraph companies
to become a media conglomerate.
