Fibonacci[b] (/ˌfɪbəˈnɑːtʃi/,[4] also US: /ˌfiːb-/;[5][6] Italian: [fiboˈnattʃi]; c. 1170 – c. 1240–50)[7] was an Italian mathematician from the Republic of Pisa, considered to be "the most talented Western mathematician of the Middle Ages".[8]
The name he is commonly called, Fibonacci, was made up in 1838 by the Franco-Italian historian Guillaume Libri[9][10] and is short for filius Bonacci ('son of Bonacci').[11][c] However, even earlier, in 1506, a notary of the Holy Roman Empire, Perizolo mentions Leonardo as "Lionardo Fibonacci".[12]
Fibonacci popularized the Indo–Arabic numeral system in the Western world primarily through his composition in 1202 of Liber Abaci (Book of Calculation)[13][14] and also introduced Europe to the sequence of Fibonacci numbers, which he used as an example in Liber Abaci.[15]
