A man named Leonardo Pisano, who was known by his nickname, Fibonacci, and named the series after himself, first discovered the Fibonacci sequence around 1200 A.D. The Fibonacci sequence is a sequence in which each term is the sum of the 2 numbers preceding it. The first 10 Fibonacci numbers are: (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89). These numbers are obviously recursive.
Fibonacci, proper name Leonardo of Pisa (c. 1170 - c. 1250) was probably the most talented mathematician of the middle ages. His father was Guglielmo who was nicknamed Bonaccio ('good natured' or 'simple'). Leonardo's mother was Alessandra who died when he was nine years old. Leonardo's nickname was derived from the latin '''filius Bonacci''' which means 'son of Bonaccio'.
