Extractions: References to Fibonacci's Life and Times Who was Fibonacci? The "greatest European mathematician of the middle ages", his full name was Leonardo of Pisa, or Leonardo Pisano in Italian since he was born in Pisa (Italy), the city with the famous Leaning Tower, about 1175 AD. Pisa was an important commercial town in its day and had links with many Mediterranean ports. Leonardo's father, Guglielmo Bonacci, was a kind of customs officer in the North African town of Bugia now called Bougie where wax candles were exported to France. They are still called "bougies" in French, but the town is a ruin today says D E Smith (see below). So Leonardo grew up with a North African education under the Moors and later travelled extensively around the Mediterranean coast. He would have met with many merchants and learned of their systems of doing arithmetic. He soon realised the many advantages of the "Hindu-Arabic" system over all the others. D E Smith points out that another famous Italian - St Francis of Assisi (a nearby Italian town) - was also alive at the same time as Fibonacci: St Francis was born about 1182 (after Fibonacci's around 1175) and died in 1226 (before Fibonacci's death commonly assumed to be around 1250).

Biography Of Leonardo Fibonacci A short biography of the mathematician fibonacci as part of a longer Text called The Art of Algebra . http://www.lib.virginia.edu/science/parshall/fibonacc.html
Extractions: Leonardo Fibonacci ( PORTRAIT - 42K ) was born in Pisa, Italy around 1170, the son of Guilielmo Bonacci, a secretary of the Republic of Pisa and responsible, beginning around 1192, for directing the Pisan trading colony in Bugia, Algeria. Some time after 1192, Bonacci brought his son with him to Bugia. The father intended for Leonardo to become a merchant and so arranged for his instruction in calculational techniques, especially those involving the Hindu-Arabic numerals which had not yet been introduced into Europe. Eventually, Bonacci enlisted his son's help in carrying out business for the Pisan republic and sent him on trips to Egypt, Syria, Greece, Sicily, and Provence. Leonardo took the opportunity offered by his travel abroad to study and learn the mathematical techniques employed in these various regions. Around 1200, Fibonacci returned to Pisa where, for at least the next twenty-five years, he worked on his own mathematical compositions. The five works from this period which have come down to us are: the Liber abbaci (1202, 1228); the

Extractions: Leonardo Pisano is better known by his nickname Fibonacci. He was the son of Guilielmo and a member of the Bonacci family. Fibonacci himself sometimes used the name Bigollo, which may mean good-for-nothing or a traveller. As stated in [1]:- Did his countrymen wish to express by this epithet their disdain for a man who concerned himself with questions of no practical value, or does the word in the Tuscan dialect mean a much-travelled man, which he was? Fibonacci was born in Italy but was educated in North Africa where his father, Guilielmo, held a diplomatic post. His father's job was to represent the merchants of the Republic of Pisa who were trading in Bugia, later called Bougie and now called Bejaia. Bejaia is a Mediterranean port in northeastern Algeria. The town lies at the mouth of the Wadi Soummam near Mount Gouraya and Cape Carbon. Fibonacci was taught mathematics in Bugia and travelled widely with his father, recognising and the enormous advantages of the mathematical systems used in the countries they visited. Fibonacci writes in his famous book Liber abaci When my father, who had been appointed by his country as public notary in the customs at Bugia acting for the Pisan merchants going there, was in charge, he summoned me to him while I was still a child, and having an eye to usefulness and future convenience, desired me to stay there and receive instruction in the school of accounting. There, when I had been introduced to the art of the Indians' nine symbols through remarkable teaching, knowledge of the art very soon pleased me above all else and I came to understand it, for whatever was studied by the art in Egypt, Syria, Greece, Sicily and Provence, in all its various forms.

Fibonacci, Leonardo Da Pisa (ca. 1170-ca. 1240) -- From Eric Weisstein's World O Branch of Science " Mathematicians Nationality " Italian Biography Contributors " Barile fibonacci, leonardo da Pisa (ca. 1170ca. 1240) This entry contributed by Margherita Barile Italian mathematician who was the first great Western http://www.treasure-troves.com/bios/Fibonacci.html
Extractions: This entry contributed by Margherita Barile Italian mathematician who was the first great Western mathematician after the decline of Greek science. The son of a merchant, Fibonacci drew the motivation to mathematical inquiry from his commercial trips to the the Orient. It was somewhere between Barbary (Maghreb) and Constantinople (now Istanbul) that he got acquainted with the Hindu-Arabic number system and discovered its enormous practical advantages compared to the Roman numerals which were still current in Western Europe. Performing even the simplest arithmetical operations with a non-positional notation was a difficult endeavor: for this task the merchants were forced to resort to the abacus, a device where the numbers were represented by moving balls. Fibonacci exposed the new alternate computing methodbased on written algorithms rather than on counting objectsin his Liber Abaci , first issued in 1202. The book began with a presentation of what he called the ten "Indian figures" (0, 1, 2, ..., 9). It was intended as an algebra manual for commercial use, and explained the arithmetical rules using numerical examples derived, for example, from measure and currency conversion, which were translated into proportions and solved by multiplication (rule of three). The so-called Fibonacci sequence arose in this book from a concrete question concerning the growth of a rabbit population.

Por mèrito de su padre aprendiò desde muy joven E l àbaco a la manera de los Hindis : las cifrar àrabas con el cero, aùn desconocidas en Italia. El mismo Leonardo dice de haber perfeccionado estos conocimientos en sus viajes en Egipto, Siria, Sicilia y sur de la Francia, donde tuvo que ir por razones de comercio A trenta y dos años publicò la primera ediciòn del "Liber Abaci" : una obra que revolucionaba los sistemas de numeraciòn, y al mismo tiempo un manual de càlculo para el uso de los mercaderes, mejorado en el 1228 para ser dedicado a Miguel Scoto. Es del 1220 el "De practica geometriae" , en el cual aplicò el nuevo sistema aritmètico para la soluciòn de problemas geomètricos: un tratado de Geometria y Trigonometria, con el cual tuvo inicio el estudio de las relaciones entre las extensiones figuradas. En el 1225 realizò el "Liber quadratorum" que constituye un brillante trabajo sobre las ecuaciones indeterminadas de 2° grado: un trabajo en el cual es visible la influencia de la tradiciòn cultural àraba.

Extractions: Fibonacci, Leonardo, also known as Leonardo of Pisa ((c. 1170-c. 1250) Italian mathematician. He published Liber abaci/The Book of the Calculator in Pisa 1202, which was instrumental in the introduction of Arabic notation into Europe. From 1960, interest increased in Fibonacci numbers, in their simplest form a sequence in which each number is the sum of its two predecessors (1, 1, 2, 3, 5, 8, 13, ...). They have unusual characteristics with possible applications in botany, psychology, and astronomy (for example, a more exact correspondence than is given by Bode's law to the distances between the planets and the Sun). He travelled extensively in the Mediterranean region. Returning to Pisa in about 1200, he began his mathematical writings. In 1225 he won a mathematical tournament in the presence of Holy Roman Emperor Frederick II at the court of Pisa. A marble tablet dated 1240 appears to refer to Fibonacci as being awarded an annual pension for his accountancy services to the state. Liber abaci was a thorough treatise on algebraic methods and problems in which he strongly advocated the introduction of the Indo-Arabic numeral system, comprising the figures 1 to 9, and the innovation of the 'zephirum' - the figure (zero). Dealing with operations in whole numbers systematically, he also proposed the idea of a bar (solidus) for fractions.
