The creators of computers

By Ariel Grinshpoon 5D

Alan Turing

• Alan Turing was a British mathematician who was influential in providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine.

• He made the ACE (Automatic Computing Engine) from 1945 to 1947.

• He also made the LU decomposition - method for solving matrix equations.

Arthur Pollen

• In the early 1900s Pollen recognised the need for a computer-based fire-control system.

• The system took twelve years to develop and included the world's first electrically powered mechanical analogue computer

• Mark III was based on Pollen’s work, which helped the navy.

Bill English

• Computer engineer• Worked at Xerox and Sun Microsystems• Contributed to the development of the

computer pointing device – the mouse.

• Bill Hewlett and Dave Packard are the electrical engineers that founded the Hewlett-Packard company – aka HP.

• HP provides variety of hardware such as:– Computers– Printers– Scanners– PDA’s

Blaise Pascal

• Did pioneering work on calculating machines – inventor of the mechanical calculator.

• Pascal’s Triangle - convenient tabular presentation for binomial coefficients.

Charles Babbage

• He was an an English polymath • Originated the concept of a programmable

computer – considered a “father of the computer”

• Inventor of the mechanical computer

Charles Xavier Thomas de Colmar

• He invented the first commercially successful mechanical calculator - it was called the arithmometer.

• Made one of the most successful French insurance companies.

algebraic logic• Inventor of the what is now known as Boolean

Logic

George Stibitz

calculator

Harry Huskey

Turing • Designed and managed the construction of

the Standards Western Automatic Computer (SWAC)

Herman Hollerith

• An American statistician and inventor who developed a mechanical tabulator based on punched cards to rapidly tabulate statistics from millions of pieces of data.

• He was the founder of the Tabulating Machine Company that later merged to become IBM.

• Regarded as the father of modern machine data processing

Howard Aiken

• Was a pioneer in computing, being the original conceptual designer behind IBM's Harvard Mark I and other versions of the computer

• Aiken’s contribution was the introduction of a master's program for computer science at Harvard - starting ground to future computer scientists

J.C.Licklider

• An American psychologist and computer scientist who is considered one of the most important figures in computer science and general computing history.

• An Internet pioneer with an early vision of a worldwide computer network long before it was built

John Mauchly

• An American physicist who, along with J. Presper Eckert, designed ENIAC, the first general purpose electronic digital computer, as well as EDVAC, BINAC and UNIVAC I, the first commercial computer made in the United States.

John Presper Eckert

• An American electrical engineer and computer pioneer• With John Mauchly he invented the first general-

purpose electronic digital computer - ENIAC• Presented the first course in computing topics - The

Moore School Lectures• Founded the first commercial computer company The

Eckert–Mauchly Computer Corporation• Designed the first commercial computer in the U.S.,

the UNIVAC, which incorporated Eckert's invention of the mercury delay line memory.

John Vincent Atanasoff

• An American physicist and inventor, best known for inventing the first electronic digital computer.

• His special-purpose machine has come to be called the Atanasoff–Berry Computer.

Joseph-Marie Jacquard

• A French weaver and merchant.• He played an important role in the

development of the earliest programmable loom - the "Jacquard loom“

• “Jacquard loom” – prdescessor of compute punch cards

Konrad Zuse

• Was a German civil engineer, inventor and computer pioneer.

• His greatest achievement was the world's first programmable computer

• The functional program-controlled Turing-complete Z3 became operational in May 1941.

• He designed the first high-level programming language, Plankalkül.

Robert Metcalfe

• An electrical engineer from the United States who co-invented Ethernet

• Founde 3Com• Formulated Metcalfe's Law – a law for

designing telecommunications networks.

Seymour Cray

• An American electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades

• Founded Cray Research

Stephen Wozniak

• An American inventor, electronics engineer, and computer programmer

• Co-founded Apple Computer• Designed Apple – I and Apple – II • Founded CL 9 – company that made

programmable universal remote controls• Founder of Wheels of Zeus

Steven Jobs

• Was an American entrepreneur, marketer, and inventor

• Co-founder, chairman, and CEO of Apple Inc.• Co-founded and served as chief executive of

Pixar Animation Studios• Played a role in introducing the LaserWriter –

first widely available laser printers

Tom Kilburn

• An English engineer. • He and Frederic C. Williams made the

Williams-Kilburn tube.• He made the Manchester Mark I. • He also made the Atlas computer. • Another of his inventions was the MU5 – next

generation Atlas computer.

Tommy Flowers

• A British engineer• Designed Colossus, the world's first

programmable electronic computer, to help solve encrypted German messages.

William Thomson, Lord Kelvin

• A British mathematical physicist and engineer• He did important work in the mathematical

analysis of electricity and formulation of the first and second laws of thermodynamics

• He also had a career as an electric telegraph engineer and inventor - for his work on the transatlantic telegraph project he was knighted by Queen Victoria, becoming Sir William Thomson.
