Bonacci was the father of Fibonacci, an Italian mathematician who lived in the 13th century. Fibonacci is best known for his work on the Fibonacci sequence, a series of numbers in which each number is the sum of the two preceding ones. The sequence begins with 0 and 1, and continues as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on.
