The Many Names

Leonardo Pisano Fibonacci was born in 1170 in Pisa [1, p. 604]. His name at birth was simply Leonardo, but in popular works today he is most commonly referred to as Fibonacci (from filio Bonacij, literally meaning son of Bonacci, but here taken as of the family Bonacci, since his father's name was not Bonacci, according to [1, p. 604]). Interestingly enough there is no proof that Fibonacci was known as such in his own time, and it has been suggested that the name Fibonacci originated with Guillame Libri [3, xv]. Fibonacci was also known by the nickname "Bigollo", which may be taken to mean loafer, and may have expressed the general lack of interest in the purely theoretical mathematics Fibonacci showed interest in. However Bigollo may also be interpreted as "well traveled", which adequately describes Fibonacci [2]. However these explanations of the nickname Bigollo have also been termed "fanciful", and having "no merit" [3, xv]. Fibonacci used the name Leonardo Pisano, which simply made reference to his origin in the city of Pisa. Now that the many names of Leonard

Leonardo Pisano Fibonacci

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 and recognised the enormous advantages of the mathematical systems used in the countries they visited. Fibonacci writes in his famous b

The life and numbers of Fibonacci

For a brief introduction to the Fibonacci sequence, see here.

Fibonacci is one of the most famous names in mathematics. This would come as a surprise to Leonardo Pisano, the mathematician we now know by that name. And he might have been equally surprised that he has been immortalised in the famous sequence – 0, 1, 1, 2, 3, 5, 8, 13, ... – rather than for what is considered his far greater mathematical achievement – helping to popularise our modern number system in the Latin-speaking world.

The Roman Empire left Europe with the Roman numeral system which we still see, amongst other places, in the copyright notices after films and TV programmes (2013 is MMXIII). The Roman numerals were not displaced until the mid 13th Century AD, and Leonardo Pisano's book, Liber Abaci (which means "The Book of Calculations"), was one of the first Western books to describe their eventual replacement.
