Mathematician. The son of an Italian warehouse manager in Algeria, Fibonacci studied with a Moorish teacher and learned the Hindu-Arabic numeral system, which he brought to Italy and introduced in his book "Liber Abaci ("The Book of Calculation)" in 1202. His work is largely responsible for the dominance of the Hindu-Arabic numeral system (sometimes called the decimal system) in the Western world today. Fibonacci is perhaps best known for the number sequence that bears his name. The Fibonacci Sequence (1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233) is the answer to the question of how many pairs of rabbits there would be at the end of twelve months if one started with one pair which did not reproduce in the first month, but produced one pair of offspring in each month thereafter, and all the pairs followed the same reproduction pattern. His other mathematical writings were "Practica Geometriae (The Practice of Geometry)" (1220), "Liber Quadratorum (The Book of Square Numbers)" (1225), and "Flos (The Flower)" (1225).
