10. Charles Babbage (26 December 1791 - 18 October 1871)- Came up with the idea of an electrical computer
was an English polymath A mathematician, philosopher, inventor and mechanical engineer, Babbage is best remembered for originating the concept of a programmable computer.Considered a "father of the computer",Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century.
9. Alan Turing (23 June 1912 - 7 June 1954)
-Created the Bombe computer, to break the Enigma code, saving millions of lives in the war.
-was a British pioneering computer scientist,mathematician, logician, cryptanalyst, theoretical biologist, and marathon and ultra distance runner. He was highly influential in the development of computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.
8. Tommy Flowers
-was a British engineer who designed Colossus, the first digital, programmable, electronic computer.
With a degree in electrical engineering from London University, he joined the telecommunications branch of the General Post Office (GPO), and worked in its research station exploring the use of electronics for telephone exchanges.
His knowledge of switching electronics would prove crucial for his computer design in the war. Like Turing, he was worked on breaking a teletype-based cipher that was even more complex than the Enigma system.
The decoding procedure involved trying so many possibilities that it was impractical to do by hand.
In February 1943, Flowers proposed an electronic system (Colossus) using 1500 valves which operated five times faster and was more flexible than the previous system, code-named Heath Robinson, that used electro-mechanical switches.
Ten Colossus machines were completed and used in British decoding efforts. For his efforts, Flowers received only limited recognition, an MBE and £1,000.
After the war, Flowers returned to the Post Office Research Station where he was head of the Switching Division.
He died in 1999 aged 94.-
- Great mathematician, came up with computer architecture.
-as a Hungarian-American pure and appliedmathematician, physicist, inventor, polymath, and polyglot. He made major contributions to a number of fields, includingmathematics (foundations of mathematics, functional analysis, ergodic theory, geometry, topology, and numerical analysis), physics(quantum mechanics, hydrodynamics, and fluid dynamics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics.He was a pioneer of the application of operator theory to quantum mechanics, in the development of functional analysis, a principal member of the Manhattan Project and theInstitute for Advanced Study in Princeton (as one of the few originally appointed), and a key figure in the development of game theory and the concepts of cellular automata, the universal constructor, and the digital computer.
6. Douglas Engelbart (30 January 1925)- Developed modern computer interaction standards. Change the mouse from a 2 wheeled wooden object, to what we still use today.
-was an American engineer and inventor, and an early computer andInternet pioneer. He is best known for his work on founding the field of human–computer interaction, particularly while at hisAugmentation Research Center Lab in SRI International, resulting in the invention of the computer mouse, and the development ofhypertext, networked computers, and precursors to graphical user interfaces. These were demonstrated at The Mother of All Demos in 1968. Engelbart's Law, the observation that the intrinsic rate of human performance is exponential, is named after him.
-was an American businessman. He was best known as the co-founder, chairman, and chief executive officer (CEO) of Apple Inc.; CEO and largest shareholder of Pixar Animation Studios, a member of The Walt Disney Company's board of directors following its acquisition of Pixar; and founder, chairman, and CEO ofNeXT Inc. Jobs is widely recognized as a pioneer of the microcomputer revolution of the 1970s, along with Apple co-founder Steve Wozniak. Shortly after his death, Jobs's official biographer, Walter Isaacson, described him as the "creative entrepreneur whose passion for perfection and ferocious drive revolutionized six industries: personal computers, animated movies, music, phones, tablet computing, and digital publishing."
4. Philip Don Estridge (23 June 1937 - 2 August 1985)
- Developed the IBM PC
-known as Don Estridge, led development of the original IBM Personal Computer (PC), and thus is known as "father of the IBM PC". His decisions dramatically changed the computer industry, resulting in a vast increase in the number of personal computers sold and bought, thus creating an entire industry of hardware manufacturers of IBM PCs.
Estridge was born in Jacksonville, Florida. His father was a professional photographer. He graduated from Bishop Kenny High School in 1955, and from the University of Florida in 1959. He married Mary Ann Hellier in September, 1958, and they had three children: Patricia Ann, Mary Evelyn and Sandra Marie.
He completed a bachelor's degree in electrical engineering at the University of Florida, and worked at the Army, designing a radar system using computers, IBM and finally NASA's Goddard Space Flight Center until he moved to Boca Raton, Florida in 1969.
Before being the leader of the team to develop the IBM PC he had been the lead manager for the development of the IBM Series/1mini-computer. After this project was unsuccessful, he was said to have fallen out of grace with IBM and was reassigned to headquarters staff - a position that IBM employees often considered a form of penalty.
- Co founder of Intel, eponymous law.
-In 1968, Robert Noyce and Gordon Moore were two unhappy engineers working for the Fairchild Semiconductor Company who decided to quit and create their own company at a time when many Fairchild employees were leaving to create start-ups.People like Noyce and Moore were nicknamed the "Fairchildren".
Robert Noyce typed himself a one page idea of what he wanted to do with his new company, and that was enough to convince San Francisco venture capitalist Art Rock to back Noyce's and Moore's new venture. Rock raised $2.5 million dollars in less than 2 days.

2. Bill Gates (28 October 1955)
- Microsoft
-is an American business magnate, philanthropist, investor, computer programmer, and inventor. In 1975, Gates co-founded Microsoft, that became the world's largest PC software company, withPaul Allen. During his career at Microsoft, Gates held the positions of chairman, CEO and chief software architect, and was the largest individual shareholder until May 2014. Gates has authored and co-authored several books.
Starting in 1987, Gates was included in the Forbes list of the world's wealthiest people and was the wealthiest overall from 1995 to 2014—excluding a few years after the Financial crisis of 2007–08. Between 2009 and 2014 his wealth doubled from $40 billion to more than $82 billion. Between 2013 and 2014 his wealth increased by $15 billion. Gates is currently the richest man in the world.

1. Tim Berners-Lee (8 June 1955)
- inventor of the World Wide Web.
-also known as TimBL, is an English computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989, and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP)client and server via the Internet sometime around mid-November of that same year.
Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the Web's continued development. He is also the founder of the World Wide Web Foundation, and is a senior researcher and holder of the Founders Chair at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL). He is a director of the Web Science Research Initiative(WSRI), and a member of the advisory board of the MIT Center for Collective Intelligence.[11][12] In 2011 he was named as a member the Board of Trustees of the Ford Foundation.
