  • Abu Ja`far Mohammed ibn Musa al-Khowarzmi
    825 BCE

    Abu Ja`far Mohammed ibn Musa al-Khowarzmi

    This Persian mathematician discovered the algorithm
    wich derives of the name of his deiscoverer. [aj]
  • Plato
    600 BCE

    Plato

    introduced the ideas or abstractions of mathematics.[aj]
  • Aristotle
    500 BCE

    Aristotle

    presesnted: deductive and systematized reasoning.[aj]
  • zero
    500 BCE

    zero

    The Hindu numbering system invented zero. [a,j]
  • Euclid
    350 BCE

    Euclid

    established the anxiomatic methood.[a.j]
  • The Romans
    1 BCE

    The Romans

    invented the abacus. [a,j]
  • Leonardo Fibonacci
    1202

    Leonardo Fibonacci

    He travelled extensively through North Africa, where he learned the arabic numbering and positional use of zero, after this,Fibonacci wrote a book that served to introduce Arabic numerals into Europe.[aj]
  • Geronimo Cardano
    1545

    Geronimo Cardano

    This Italian mathematician, demonstrated that debts and similar phenomena could be treated with negative numbers. [a,j]
  • Francois Viéte
    1580

    Francois Viéte

    began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra.[a.j]
  • John Napier

    John Napier

    invented logarithms. [a,j]
  • Edmund Gunter

    Edmund Gunter

    He invented a precursor to the calculation rule.[a.j]
  • Wilhem Schickard

    Wilhem Schickard

    Schickard designed and built what is considered the first digital calculator. Schickard's calculator allowed automatic additions and subtractions, and partially automated, multiplications and divisions. Unfortunately, Schickard and his entire family died during an epidemic, and hisinventionhad no diffusion. [a,j]
  • Galileo

    Galileo

    Galileo laid the foundations for mathematical formulation.[a.j]
  • René Descartes

    René Descartes

    He discovered analytical geometry.[ja]
  • Blaise Pascal

    Blaise Pascal

    Although he is generally regarded as the inventor of the calculator, he manufactured his wits twenty years after Schickard and was less advanced. It was based on a toothed wheel system and given the technology of the time failed to manufacture any reliable models.[a.j]
  • Gottfried Wilhelm Leibniz

    Gottfried Wilhelm Leibniz

    He was, along with Isaac Newton, the co-discoverer of calculus.Based on Pascal's work he built a device, known as the Leibniz wheel. This device could automatically perform additions, subtractions, multiplications and divisions. Leibniz was also the first Western thinker to investigate binary arithmetic and laid the foundations for symbolic logic, based on symbols and variables abstracting the semantics of propositions. [a,j]
  • Charles Babbag

    Charles Babbag

    He was one of the founding members of the Royal Astronomical Society of England. He proposed two computer machines moved by steam machines.[a.j]
  • Pehr George Scheutz

    Pehr George Scheutz

    Managed in to build a highly specialized "differential" machine. It operated using punched cards containing series of operations and data. [a,j]
  • Boole

    Boole

    His most prominent contribution was a book "An Investigation into the Laws of Truth"[a.j]
  • John V. Atanasoff

    John V. Atanasoff

    Physicist, and associate professor at Iowa State University, with the help of an undergraduate student named Clifford E. Berry. built the ABC (Atanasoff Berry Computer), it used binary arithmetic and was single-purpose. [a,j]
  • John von Neumann

    John von Neumann

    An outstanding mathematician, became interested in the design of computers. When he was twenty-three he was already a renowned mathematician throughout the world. He had carried out important studies in formal logic and collaborated to axiomatize mathematics. Von Neumann combined the systematization of logic and the possibility of performing calculations quickly and reliably. [a,j]
  • Howard T. Aiken

    Howard T. Aiken

    Collaborated with a group of IBM engineers, designed and built an electromechanical machine (Mark 1) capable of multiplying two numbers in six seconds and dividing them by twelve.[a.j]
  • John Mauchly

    John Mauchly

    The designer of ENIAC, the first large-scale digital computer.[a.j]
  • John Backus

    John Backus

    He developed the first high-level language called FORTRAN (FORmula TRANslator). [a,j]
  • Grace Hopper

    Grace Hopper

    She developed a high-level language (for computing) called COBOL (Common Business-Oriented Language).[a.j]
  • J.C.R. Licklider

    J.C.R. Licklider

    He wrote an essay on the concept of the Intergalactic Network, where the whole world is interconnected and can access programs and data from anywhere on the planet. In October of that year, Lickider was the first director of ARPA. [a,j]
  • Niklaus Wirth

    Niklaus Wirth

    He developed de high-level language PASCAL.[a.j]
  • Vinton Cerf

    Vinton Cerf

    He began the development of the protocol that would later be called TCP / IP, a protocol aimed at communicating some networks over others. [a,j]
  • William Gibson

    William Gibson

    He was thw one who novelized the new world and coined the term "cyberspace". [a,j]
