Leonardo Fibonacci By Crystal Gaudio Leonardo Fibonacci was a twelfth century mathematician born near the year 1180 into the privileged class of Pisa. His father Bonacci was a Pisan business and government official. Because of his elevated status, Fibonacci attended public school and studied the "seven liberal arts": grammar (Latin), rhetoric, logic, geometry, astronomy, music and arithmetic. During Fibonacci's life, Pisa participated in the Commercial Revolution of the twelfth and thirteenth centuries, out of a Roman port that continued operation through the Dark Ages. Pisa was a site of extensive commercial activity requiring calculation on an abacus and recording with Roman numerals. After his formal public education, Fibonacci followed his father to North Africa, Bugia to continue his business education. There he discovered the long established HinduArabic numerals similar to what we use today. The numerals consisted of symbols 1-9 and the extraordinary concept of zero. Fibonacci was responsible for introducing the HinduArabic numerals to Western Europe in his publication Liber abaci (Book of the Abacus) . Fibonacci was also responsible for introducing the Arab method of balancing income and expenditure in the double-entry system of bookkeeping. Another section of Liber abaci calculated the progeny of a single pair of rabbits. Through systematic calculations involving logic and consistency, the "Fibonacci Sequence" was created. In subsequent months, the number of paired rabbits would theoretically continue as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89...or u

A brief biographical sketch of Fibonacci, his life, times and mathematical achievements. Contents of this Page Who was Fibonacci? His names Fibonacci's Mathematical Contributions Introducing the Decimal Number system into Europe ... 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 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

Barile Fibonacci, Leonardo da Pisa (ca. 1170-ca. 1240) 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.

Bibliography Introduction Fibonacci was known for many things. He was best known for the Fibonacci Numbers, which is a number sequence that he had discovered while solving a problem about rabbits. There is a lot more that we will talk about him and his discoveries which are now coming up. Biography From 529 until 1500 A.D. there were no big improvements in european mathematics. Except for Fibonacci, who was a great 13th century mathematician. He was born in Pisa, Italy, and was the son of a pisan merchant. Fibonacci was best known as Leonardo of Pisa. His father was also a customs officer for the North African city of Bugia. Since Fibonacci was the son of a merchant, he was able go travel freely all over the Byzantine Empire. Merchants at the time were immuned, so they were allowed to move about freely. This allowed him to visit many of the area's centers of trade. While he was there, he was able to learn both the mathematics of the scholars and the calculating schemes in popular use, at the time.

LEONARDO FIBONACCI Mathematician Also known as Leonardo of Pisa, Fibonacci introduced to Europe and popularized the Hindu-Arabic number system (also called the decimal system). He contributed greatly to number theory, and during his life published many important texts, including Liber abbaci Practica geometriae (1220) and Liber quadratorum (1225). He is also known for the Fibonacci Series, a numerical series found frequently in the natural world. In the sequence, each number is equal to the sum of the preceding two (1, 1, 2, 3, 5, 8, 13, 21 ...). For other explanations of terms and phrases from famous names, see our loop of Who's What?

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 and recognised 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.
