Leonardo Fibonacci was an Italian mathematician who lived between 1170-1240. He travelled a lot on business with his father and was exposed to many different mathematical techniques used in western Europe, Asia, and northern Africa. Fibonacci accumulated techniques in arithmetic, algebra, and geometry during his travels, and compiled them in books, for people to learn without having to travel as he had. His writings also introduced Arabic numerals into European mathematics.
Fibonacci made significant contributions to mathematics himself, in
number theory and in recursive sequences. He is most famous for the sequence
bearing his name, in which each number is the sum of the previous two.
