Leonardo Fibonacci
He was an Italian mathematician and he was the first to write about Arabic numerals in the West and he learned Arabic numbering and positional notation with zero. He wrote book that served to introduce Arabic numerals into Europe. -

Geronimo Cardano
He was an Italian mathematician was the one who demonstrated, in 1545, that debts and similar phenomena could be treated with negative numbers. -

Francois Viéte
He began to use letters to symbolize unknown values (variables) and thus laid the foundations of algebra. -
John Napier
Was a Scottish mathematician and inventor that invented logarithms. He also made the use of the decimal point in arithmetic operations common. -
Galileo Galilei
He laid the foundations for mathematical formulation. -
Edmund Gunter
Edmund Gunter was an English clergyman and mathematician. He invented a precursor to the calculation rule. -
Wilhelm Schickard
He designed and built what is considered the first digital calculator. Schickard's calculator allowed automatic additions and subtractions, and partially automated,
multiplications and divisions. His entire family died during an epidemic, and his invention had no diffusion -
René Descartes
He discovered analytical geometry. -
Blaise Pascal
He was the inventor of the calculator,
manufactured his wits twenty years after Schickard and was less advanced. -
Gottfried Wilhelm Leibniz
He was an excellent theoretical thinker and a prominent pragmatic man. He wrote: "It is a waste of time for qualified people to waste hours as slaves in the work of calculating, which could be delegated to
anyone else if machines could be used.". Some machines based on the same principles as Leibniz's,
have played a leading role in World War II. He was also the first Western thinker to investigate binary arithmetic and laid the foundations for symbolic
logic. -
Charles Babbage
He was one of the founding members of the Royal Astronomical Society of England. He proposed two computer machines moved by steam machines. -
Georges Boole

Herman Hollerith
Created a punch card technology that was used to control the census. This technology proved to be faster and allowed more questions to be asked in the census questionnaire. -
John V. Atanasoff
His main interest was to find an efficient method to solve systems of linear equations. -
John von Neumann
He began working on the ENIAC project and took part in discussions about the design of a new machine, the EDVAC. -
Howard T. Aiken
He designed and built, in 1944, an electromechanical machine named Mark 1 capable of multiplying two numbers in six seconds and dividing them by twelve. -
John Mauchly
The designer of ENIAC, the first large-scale digital computer. -
John Backus
Created FORTRAN. Winner of the Turing Award in 1977 for his work on high-level programming systems. -
Grace Hopper
Created Common Business-Oriented Language. -
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. -
Nicklaus Wirth
Created PASCAL. In 1959 he obtained the title of Electronic Engineer at the Federal Polytechnic School of Zurich in Switzerland. -
Vinton Cerf
Began the development of the protocol that would later be called TCP / IP. -
William Gibson
