Leonardo of Pisa Facts
 Leonardo Pisano Bigollo (c. 1170 - c. 1250) was referred to by many nicknames and titles, including Fibonacci, Leonardo of Pisa, Leonardo Pisano, Leonardo Bonacci, and Leonardo Fibonacci.
Interesting Leonardo of Pisa Facts:
Leonardo was an Italian mathematician, considered by some researchers to be perhaps the most gifted mathematician of the Middle Ages.
Fibonacci is believed to have been born in or close to 1170; as the son of a wealthy merchant, Guglielmo Bonacci, Leonardo was able to travel extensively as a child.
While traveling with his father to a trading post in northern Africa, Leonardo first learned the Hindu-Arabic numberals.
He recognized the inherent ease and capabilities of the system, and saw that they were far more workable than the Roman numeral system then in use in Italy.
He is best known for being instrumental in bringing the Hindu and Arabic numeral systems to Europe.
He introduced the numbers systems from that regions through his book, Liber Abaci (Book of Calculation) (1202).
He is also remembered for a number sequence named after him, the Fibonacci numbers.
Leonardo did not discover the Fibonacci number, but used the sequence an example in his important book.
In his book, he supported the system of numeration that follow the digits 0-9 and their place values.
He demonstrated the practical efficiency of this kind of numbering by applying it to a wide variety of mathematics-based areas of commerce, such as bookkeeping, weights and measures, interest and money-changing, and other applications.
Unlike accounts of researchers whose ideas seem too radical for their day, Liber Abaci was well received among most of the educated people of Europe, and made a significant impression on education.
The Fibonacci number is the series of numbers starting with one (in Leonardo's calculation) or zero (in modern calculation) and adding the next digit to itself until that sum is later added. The sequence is as follows: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377.
This number sequence was the solution to an understanding on rabbit populations and their exponential growth.
While Leonardo is credited with bringing this understanding to Europe, Arab mathematicians had solved this problem sequence as early as the sixth century.
