1.- Blaise Pascal
He was born on June 19, 1623
in Clermont, and died on August 19, 1662 in Paris. he was a mathematician,
physicist, philosopher and writer
Pascal was the first to
design and build an adding machine called the Pascaline. He wanted to help his
father, who was a tax collector, with the arithmetic. The machine was
mechanical and had a system of gears each with 10 teeth, each tooth had
recorded a digit between 0 and 9. the machine was capable of doing adition and
subtraction
2.- Gottfried
Wilhelm Leibniz
He was born in Leipzig on July 1, 1646 and died in Hanover on November
14, 1716. he was a philosopher, mathematician, lawyer, librarian and a German
politician.
He began to work on perfecting the adding machine of Blaise Pascal,
invented in 1642. Leibniz tried to improve it so that it was able to multiply
and divide. Was achieved by a mechanical device called "Leibniz
cylinder"
He invented the binary system, the base of all current computer
architectures. He developed theories to create the computers.
3. Charles Babbage
He was born in Britain on December 26 de1791 and died on October 18,
1871
He designed and partially implemented a machine to calculate the
mechanical differences to calculate tables of numbers. He also designed but
never built, the analytical engine to run programs or computer tabulation, for
these inventions is regarded as one of the first people to conceive of what we
now call a computer, which is regarded as "the Computer the Father of the
computer "
he suggested the use of punched cards to control his machine, and
anticipated the use of them to represent an algorithm and even invented the
concept of loops or cycles in programming.
4.- George Boole
He was born November 2, 1815 and died on December, 1864. He was a
British mathematician and philosopher.
He invented the "Boolean algebra", which marks the
fundamentals of modern computer arithmetic, and what is used by all modern
computers, to express if one input is true or false. Boole is regarded as one
of the founders of the field of Computer Science
5. Augusta Ada Byron
She was born on December 10,
1815, and died in 1852
During this period, which
lasted ten years she followed in detail the genesis of the Analytical Engine.
Writing "diagrams" for this machine that worked using gears, these
diagrams were intended to explain what the machine should do to get the desired
result - which corresponds to what we now call programming. ADA is considered
as the first "programmer". She deduced and predicted the ability of
computers to go beyond the simple calculation of numbers
Ada was the first person to
write a program for a programmable computer, wrote a "plan" which
describes the steps that would calculate the values of the Bernoulli numbers,
the first program, which used two loops, with this, she demostrated the ability
of branching of the Babbage's machine
6. John Von Neumann
He was born on December 28,
1903 and died on February 8, 1957
the contributions of von
Neumann, ranging from memory usage to the concept of randomness, and even the
problem of reproducible construction of robots, laying the bases of current
developments as Artificial Life. He also participated actively in the design of
the first computers: Mark and ENIAC.
7. Konrad Zuse
He was born on June 22, 1910
and died on December 18, 1995. His crowning achievement was the completion of
the first computer-controlled programs, the Z3 in 1941. This may have been the
"first computer"
He designed a high level
programming language “the Plankalkül” in 1945, it was jut a theoretical
contribution, the language was not implemented in his life and had no direct
influence on the first languages developed.
The Z1 thah Zuse created in
1936, in his living room using very thin sheets of metal, it was completely
mechanical except for a motor who was working with
frequency of 1 Hz
8.-
Alan Turing
He was born on June 23,
1912 in London and died on June 7, 1954 in Cheshire
He provided an influential formalization of the concepts of algorithm
and computation. During World War II, he worked to decipher Nazi codes, particularly
the Enigma machine ones. He designed the first digital electronic computer made
with bulbs. Turing was a great mathematician, logic and theoretical computer
science. As a graduate student at Princeton University in 1936, published the
article "On computable numbers", which established the theoretical
basis for modern computing. He set the boundaries of computer science by
showing that there are problems that no computer can solve.
9. J. Presper Eckert
He was born in Philadelphia,
U.S. on April 9, 1919 and died on June 3 de1995. In 1943, Eckert was appointed
chief engineer of the project, whose specific task was to design electronic
circuits. One of the problems he solved was getting the 18000 valve which ENIAC
was made of, had a long life so that the ENIAC was made of, was viable.
He also handled
the design of the base 10 calculators for the ENIAC.
He created the company
"Electronic Control" building different computers, as the BINAC, in
which, the data were stored on magnetic tapes, or UNIVAC, which was the first
to be marketed in the U.S..
10. John W. Mauchly
He was born
August 30, 1907 and died on January 8, 1980.
Along with John Presper
Eckert, designed ENIAC, the first program and the first electronic digital
computer of general purpose as well as EDVAC, UNIVAC and Binac
Pioneers in some fundamental
concepts of computers, including the "stored program", subroutines
and programming languages, he influenced an explosion in development of
computers in the late 40 anywhere in the world.
He created the "SHORT CODE", the
first programming language currently used in a computer. It was a pseudo-code
interpreter for mathematical problems proposed in 1949 and worked on the UNIVAC
I and II. Mauchly's belief in the importance of languages brought him to hire
Grace Murray Hopper to develop a compiler for the UNIVAC
