John Napier
He's best known as the inventor of logarithms. He is also credited to have made the use of the decimal point in arithmetic and mathematics common. -
First Calculator
It made computations quicker and more exact. -
Charles Babbage
Charles Babbage invents the Analytical Engine, which many consider to be the precursor to modern computers. He's known as "the father of computer". -
Ada Lovelace
Ada Lovelace has been called the world's first computer programmer. She continued from where Babbage left off and wrote the world’s first machine algorithm for an early computing machine that existed only on paper. -
Alan Turing
During World War II, he developed a machine that helped break the German Enigma code and save millions of lives. He also designed an experiment now known as the “Turing Test.” A method of testing a machine’s ability to show human-like behavior. -
Atanasoff-Berry Computer
Atanasoff and his graduate student, Clifford Berry, design a computer that can solve 29 equations simultaneously. This marks the first time a computer is able to store information on its main memory. -
Tommy Flowers
He designed and built Colossus, the world's first programmable electronic computer, to help solve encrypted German messages. -
First Keyboard
People could efficiently enter in information and save more time compared to using punch cards. -
Walter Brattain
He invented the first working transistor. Amplifying small electrical signals and supporting the processing of digital information, the transistor is "the key enabler of modern electronics". -
Jack Kilby
He headed teams that created the first military system and the first computer incorporating integrated circuits. -
Dr. Grace Murray Hopper
She helped develop COBOL, one of the first high-level programming languages, and invented the first compiler, a program that translates programming code to machine language. -
First Video game
It increased the risk of aggressive behavior in certain children. Therefore children began to think that violence is a normal behavior as shown in the games. -
Computer Mouse
The mouse revolutionized computer interfaces, created an easy way to manipulate information on a screen, and simplified an otherwise scary machine. -
Email is invented
Email has made communication instant and global. Families and friends can keep in touch much more easily, saving time and money.
We are communicating more quickly, with more people, across a greater area, than ever before. -
First Portable Computer
Altair produced the first portable computer. He paved the way for many of the big computer companies who made computers personal. -
Bill Gates and Paul Allen founded Microsoft
Microsoft designed personal computers and made them easy to use at home. At that time, computers were seen as complex devices that were used for large enterprises, but Microsoft was the first to change that perception. -
Steve Jobs and Steve Wozniak founded Apple
Apple’s iPhone changed the way phones were designed and started the smartphone industry. It put the internet in everyone’s pocket and transformed photography from a hobby to a part of everyday life. -
Philip Don Estridge
He led development of the original IBM Personal Computer, and thus is known as the "father of the IBM PC” -
The World Wide Web is invented
The World Wide Web enabled instant communication that affects almost every aspect of life. Some examples are instant messaging, online shopping, blogging, and marketing. -
Sergey Brin
Along with Larry Page, he created the online search engine Google.
