Fibonacci means (a) son of Bonacci. His mother was Alessandra Larracocci. He was 9 when she died. He had a sister named Saminta. He is considered the "Father of Mathematics".

[change] Fibonacci number sequence

Fibbonacci is best known for the list of number called the Fibonacci Sequence. The list never stops, but is starts this way:

1,  1,  2,  3,  5,  8,  13,  21,  34,  55,  89, ...

In this list, a person can find the next number by adding the last two numbers together.

1 + 1 = 2
    1 + 2 = 3
        2 + 3 = 5
            3 + 5 = 8
                5 + 8 = 13
                    8 + 13 = 21
                        13 + 21 = 34
                             21 + 34 = 55
                                  34 + 55 = 89
                                       and so on

This series is also interesting because the ratio of two adjacent numbers in the series approaches the golden ratio, or Phi, as the numbers get bigger.
